Definitions
- the present invention relates to a method for sputtering a dielectric target in a vacuum chamber with a high-frequency gas discharge according to the preamble of claim 1, as well as a sputtering target according to the preamble of claim 8 and a magnetron sputtering source with the corresponding sputtering target.
- the dielectric layer is deposited on the workpiece, in particular the plastic workpiece, in a vacuum chamber using the known high-frequency cathode sputtering method, in particular with magnetron sputtering. Such layers are used in particular in the production of storage disks.
- optical recording methods where the information is embossed in the disc itself and provided with a highly reflective layer, a laser beam being able to scan the information accordingly.
- both metallic and non-conductive dielectric layers are deposited on a substrate, the data carrier, and the conductive metallic layers are relatively easy to coat.
- two processes are in the foreground.
- One method is the so-called reactive sputtering from a conductive target.
- the atomized material in the process space or when it hits the substrate is oxidized to the non-conductive layer with the aid of the reactive gas fed into the process space.
- the other method for sputtering non-conductive substrate material is high frequency sputtering. Since the target does not conduct in this case, it can not be atomized with a DC voltage, because of the formation of a Surface charge the entire applied voltage drops across the target, and not as desired in the plasma room. This means that no current can flow through the target into the plasma space.
- the frequencies required for this are in the high-frequency range, that is in the range> 1 MHz, with the industrial frequency in the 13 MHz range being practical for practical reasons.
- the target is eroded over a larger radial area.
- the desired erosion profile can be generated, for example, by means of a rotating magnet system, by suitably arranged magnets and pole shoes, or by correction influences, for example additional magnetic fields that change over the target lifetime or briefly.
- the disks are fed in at intervals and coated in front of the target at a defined distance, the coating time generally being a few seconds to a few minutes.
- the coating time generally being a few seconds to a few minutes.
- the present invention has set itself the task of eliminating the disadvantages of the prior art, in particular to realize a coating method for dielectric materials with which a predefinable distribution profile can be achieved with high economy, and which also creates the possibility of distribution changes over the To compensate for the target lifetime of an atomization source.
- This object is achieved according to the invention by the method according to the wording of claim 1.
- the independent claims relate to advantageous further refinements.
- the dielectric and thus non-conductive sputtering target material is fastened or bonded to a so-called carrier plate or backplate for the high-frequency sputtering, this having to be done in such a way that good thermal contact arises.
- the carrier plate is necessary on the one hand to hold the brittle material and on the other hand to achieve good heat distribution.
- the carrier plate is cooled and thus indirectly the target bonded to it.
- an important application here is the deposition of dielectric layers for optical storage disks, in particular for phase change disks.
- the coating with a target material, which consists of ZnS and SiO 2 .
- targets are usually sintered during manufacture. Maintaining the highest possible layer uniformity over the process times is particularly important in this application.
- the capacitance that forms between the metallic conductive bond plate and the plasma that forms in the front area of the targets is different if the dielectric target is of different thickness compared to the bond plate in partial areas of the target. This makes it possible to influence the discharge or the discharge density locally.
- the atomization distribution can be influenced by this procedure if the target thickness is varied over the target area in the desired areas.
- the capacity between the plasma and the target carrier plate is increased in the thinner area, which means that the atomization rate also increases in these areas.
- the distribution can be influenced to the desired extent by appropriate profiling of the target.
- This type of correction option is particularly favorable when using magnetron sputtering sources, which inherently form different erosion profiles due to the magnetic field-assisted plasma generation, and which cause erosion profiles generated by the magnetic field over the target service life to shift the distribution profile. For example, in areas of strong erosion caused by the magnetic field, this pronounced erosion can be compensated for by thickening the target via the capacitive effect. In areas of weaker erosion caused by the magnetic field, thinning the target increases the dusting rate. This also makes it possible to compensate for the effect.
- the target can be profiled, for example, on the front side facing the plasma, in which case the target carrier plate on the back is designed as a flat plate.
- Another possibility is to make the target flat on the front and to profile it on the back, the target carrier plate then following the profile.
- a further possibility is also to profile the carrier plate and to arrange a further dielectric with good thermal conductivity between a flat target plate and the profiled carrier plate, which dielectric is easier to process than the target material itself and thus represents a compensating dielectric with the advantage that that the brittle target material itself can be formed as simply as possible, for example as a flat plate.
- the aforementioned profiling options can also be combined. For reasons of simple manufacturability, however, those solutions are preferred which allow the simplest possible contours or even allow a purely plate-shaped target, which makes the manufacturing process economically feasible.
- profiling In addition to simple recesses or elevations, other forms of profiling also have an effect, such as trapezoidal, spherical, toroidal ribs or grooves.
- Profiling can thus stabilize the erosion rate, but in particular the radial distribution of the erosion rate in the case of round targets, over the entire lifetime of the target. This effect does not occur when sputtering conductive target materials with RF or DC sputtering.

- FIG. 12 cross section through a profiled target according to the invention with different erosion profiles with different target service lives
- High frequency sputtering sources for vacuum coating processes are used in a variety of ways.
- the magnetron sputtering technology with magnetic field-assisted plasma generation is preferred because of the high rates that can be achieved and because of the possibility of influencing the sputtering characteristics via the magnetic field.
- Atomization sources of this type can be designed in various geometries, for example tubular with rotating target tubes, planar with planar targets, such as rectangular cathodes, or round cathode arrangements, or also as curved ones or hollow cathodes.
- the workpieces to be coated, the substrates can be moved relative to the sputtering target in order to achieve a good distribution of the deposited layer.
- FIG. 1 A typical stationary arrangement is shown schematically in FIG. 1.
- a vacuum chamber (2) is evacuated via valves (6) with a vacuum pump (5).
- the gases necessary for generating the plasma can be introduced via the gas inlet devices (7, 8) and a corresponding working pressure is set.
- the working gases used for the atomization are mainly heavy noble gases such as argon and, in the case of reactive processes, additionally reactive gases, such as oxygen, nitrogen, etc.
- the vacuum chamber (2) accommodates a substrate holder (3), which is shown here schematically as a kind of lock is formed in that it can be lowered in order to be able to equip the substrate holder (3) with a workpiece (4).
- a substrate holder (3) which is shown here schematically as a kind of lock is formed in that it can be lowered in order to be able to equip the substrate holder (3) with a workpiece (4).
- separate lock arrangements are used, so that the process space is separated from the insertion chamber and the vacuum conditions in the process area, where the atomization source (1) is also arranged, are separated.
- the atomization source (1) which receives the target (9) to be atomized, is generally arranged at a distance (d) of a few centimeters, for example 4 to 5 cm, from the workpiece (4).
- High frequency power is fed in between the target (9) and the substrate (4) or substrate holder (3) with a high frequency generator (20) to generate a plasma discharge between the target (9) and the substrate (4).
- the vacuum chamber (2) is grounded during this type of sputtering process, and the high-frequency connection on the substrate side as well, as shown in dashed lines in the figure.
- the atomization source (1) receives the target (9), which is shown in cross section in FIG.
- the figure shows a typical structure of a target arrangement (9, 10), as used in the preferred magnetron sputtering sources, according to the prior art.
- a planar, dielectric target plate (9) with a flat new target surface (13) is bonded to a carrier plate (10), which is not shown here.
- a magnet system (11), which forms the electron trap configuration for the plasma discharge, is arranged on the back of the target arrangement (9, 10).
- the magnet system (11) is preferably moved around the central axis (12) during operation in order to produce a suitable form of erosion on the target surface by eccentrically arranging the magnetic field configuration. Similar techniques are also used by linear movements, for example in the case of rectangular target arrangements.
- an erosion profile (14) is shown, which has a typical design for a magnetron sputtering source, the erosion profile essentially already representing a spent or atomized target.
- FIG. 3 again shows a cross section through a round target, as in FIG. 2 with an atomization target (9) which has a target profiling (15) on the front in the center.
- the profiling (15) is step-shaped, so that the target thickness is reduced in the center and, according to the invention, the rate is increased there by the capacitive effects of the high-frequency discharge, in order to compensate for the effect of severe erosion on the outer edge in this area.
- FIG. 4 shows how a target (9) can be profiled on the back, and how the metallic carrier plate (10) is fitted into this recess in the profiling (16) in order to achieve the inventive effect.
- FIG. 5 Another possibility of realizing different dielectric thicknesses on the target is shown in FIG. 5.
- a planar target (9) which is particularly simple and therefore economical to manufacture
- the profiling (18) in the carrier plate ' (10) and between the target (9) and the carrier plate (10) a further dielectric layer (17), which acts as a compensation layer, is provided.
- the advantage of this embodiment is that a material can be selected for the compensating dielectric (17) that can be shaped more easily than the atomizing target material (9) and thus the target production can be made considerably cheaper.
- Materials with an ⁇ between 2 to 50, for example plastics or also ceramic materials, with good thermal conductivity, such as aluminum oxide, Al 2 O 3, are suitable as compensating dielectric (17).
- the compensating dielectric (17) can be left on the carrier plate (10) and the flat neutar target (9) can be glued directly to the flat intermediate surface without the profiling itself having to be created anew each time must become.
- FIG. 6 shows how the erosion rate ER behaves as a function of the atomization energy SE (target lifetime) in kWh, measured in the three erosion zones with radius rO, r36 and r72 measured in mm from the center of the round target. It is clearly evident that the erosion rates diverge, which leads to a shift in the distribution profile on the substrate over the target lifetime (see FIG. 9).
- FIG. 7 shows the behavior of a target formation according to the invention shown in FIG. 2 in the same representation. It can be seen here that the erosion rates run uniformly over the target lifetime, which leads to a stabilization of the distribution profile on the substrate.
- the conditions were measured in both cases with a 6 mm thick target made of ZnS and SiO 2 with a diameter of 200 mm and a target substrate spacing of 40 mm, the substrate diameter being 120 mm and the frequency of the RF generator being 13 MHz.
- a flat aluminum target with the same dimensions was also atomized with the same atomization arrangement. The experiments show that the effect occurs especially with high-frequency sputtering of non-conductive materials, but not with high-frequency sputtering of conductive materials.
- FIG. 8 For a qualitative description of the effect, a very simplified electrical circuit diagram of an RF sputtering arrangement with insulating target material is shown in FIG. 8.
- the radial sputter erosion rate is represented by specific variable, depending on the radius, plasma and target impedances Zp (r) and Zt (r).
- the losses in the target determined by the loss angle delta of the dielectric target, are also important.
- the positive effect of the invention is shown again on the basis of distribution measurements on the substrate.
- a planar dielectric target according to the state of the Technology was atomized under the conditions, as already mentioned, and the distribution characteristic over the disk diameter was measured at different target service lives.
- the results can be seen in FIG. 9, where the relative layer thickness S is shown in% depending on the substrate position or distance from the center of the substrate in mm at the various operating times tll to tl5 over the target service life.
- For typical optical storage disks only the range of ⁇ 25 to 60 mm has been measured because there is a hole in the center of the plastic disc.
- the curve tll was measured at the beginning of the target life, the curve tl2 after 80 kWh, the curve tl3 after 200 kWh, the curve tl4 after 270 kWh and the curve tl5 after 385 kWh, that is to say at the end of the target life. It can be seen from the illustration that there are strong shifts and tilts in the distribution curves over the target life, with the result that the layer thickness distribution over the target life on the storage disk varies in an impermissible manner.
- the associated target is shown in cross section in FIG. 11. The different erosion profiles are shown over the target life, i.e. the target thickness in percent depending on the target radius R in mm.
- the target surface that has not yet been dusted is shown with the profile eO, el shows the erosion profile, which arises after 80 kWh operating time, e2 after 200 kWh operating time and e3 after 385 kWh operating time, that is to say at the end of the target service life.
- FIG. 12 again shows a cross section of the target, that is to say the target thickness in percent depending on the radius in mm of the target disk.
- the new condition of the profiled target surface is designated E0, El after an operating time of 60 kWh and E2 after an operating time of 121 kWh. It can be seen from the two FIGS.
- the distribution profiles Tll to T15 differ very little from one another over the entire target life. From this the stabilizing effect of the target profiling is over the target life is immediately apparent.
- a further advantage of target profiling results from the fact that the material utilization of the target increases, particularly when high requirements are placed on the layer thickness accuracy on the substrate, because the entire target thickness can be better utilized. On the one hand, this leads to better material utilization and, on the other hand, to a longer service life of the target and thus to higher throughputs per target used, which significantly increases the economy.
- a slightly higher rate can also be determined by reducing the target impedance in the zones of the reduced target thickness. The process can also be carried out more simply because hardly any more effort is required in terms of external control or readjustment of the atomization process in order to achieve a good distribution. Overall, this also simplifies the construction of the cathode and the entire arrangement.
