Cover 270. FIG. 5 is a cross-sectional view showing a wafer sealing structure according to still another embodiment of the present invention. Referring to FIG. 5, when the chip package structure 4 is fabricated, after the step of refining the metal thin plate 210, the residual mask 270 may be removed first, then the lower colloid 460 is formed, and the lower colloid 460 is covered. Table 12 1334182 CN-9509009 22l66twf.d〇c/n Face 210b. The method of removing the etching mask 27 is, for example, to dissolve the surname mask 270 using an organic solvent to remove the money mask 270. Embodiment 2 FIG. 6 is a cross-sectional view showing a wafer package structure according to a second embodiment of the present invention. It is to be noted that the same or similar element numbers as in the second embodiment and the first embodiment represent the same or similar elements, and the second embodiment is substantially the same as the first embodiment. The differences between the two embodiments will be explained in detail below, and the same points will not be described again. Referring to FIG. 6, the second embodiment is different from the first embodiment in that, in the chip package structure 500, the second raised portion 514 of the thin metal plate 510 is in a sinking design. That is, the upper surface 51 of the second boss portion 514 is lower than the upper surface 51A of the first boss portion 212 and the third boss portion 216. The lead frame 510 is formed on the metal thin plate 510, and the first convex portion 212, the second convex portion 514 and the third convex portion 216 form the wafer holder 212, the bus bar 514' and the pin 216', which may cause The busbar 514' is designed for placement so that a better mold flow balance can be achieved. In addition, those skilled in the art can also design the wafer holder 212' or the pin 216 as a sink, or the wafer holder 212', the bus bar 514', and the pin 216, either of which The group ^ is designed for sinking, and the invention is not limited thereto. THIRD EMBODIMENT Fig. 7 is a cross-sectional view showing a wafer package structure in accordance with a third embodiment of the present invention. It is to be noted that the same or similar elements as in the second embodiment and the embodiment denote the same or similar elements, and the second embodiment is substantially the same as the first embodiment. In the following, the differences between the two implementations 13 13.34182 CN-9509009 22166twf.doc/n will be explained in detail, and the same points will not be repeated. Referring to FIG. 7, the third embodiment is different from the first embodiment in that, in the lead frame 610 of the chip package structure 600, the thickness of the wafer holder 612 is greater than the thickness of the bus bar 214' and the pin 216. The thickness, while the upper surface 210a of the wafer holder 612', the busbar 214', and the pins 216, remains in the same plane. After the basic fabrication process of the chip package structure 6 is completed, the etching mask 270 on the lower surface 610b of the wafer holder 612 is removed, so that the lower surface 61〇b of the wafer holder 612' is directly in contact with the outside to effectively The heat dissipation efficiency of the wafer sealing structure 600 can be increased. In addition, the etching mask and the lower colloid can be exposed to the exposed surface of the lead. FIG. 8 is a cross-sectional view showing a wafer package structure according to still another embodiment of the present invention. Referring to FIG. 8, in the lead frame 710' of the chip package structure 7, the etching mask 27 and the lower body 26 are exposed to expose the lower surface 710b of the pin 716. Thus, the chip package structure 7 can be applied to a leadless package structure, for example, the wafer package structure 700 can be applied to a quad flat [no-lead package I structure. In addition, the skilled person in the art can also make the surname also cover the lower surface of other parts of the strip line of the rubber strip, for example, the side mask and the lower colloid can simultaneously expose the lower surface of the lead and The lower surface of the wafer holder is not limited by the present invention. In summary, the present invention proposes a novel chip package structure. The ::: convex: ί ' provides a first raised portion, a second raised portion and a plurality. A thin metal sheet. Thereafter, the wafer is disposed on the metal thin plate (10) to form a plurality of bonding wires for electrically connecting the wafer with the second raised portion and the second raised second raised portion. Next, an upper colloid is formed on the lower surface of the metal sheet 14 1334182 CN-9509009 22166twf.doc/n. Then, a residual mask is formed on the lower surface, and the remaining mask exposes a portion where the first convex portion, the second convex portion and the three convex portions are connected. Finally, the metal sheet is engraved such that the first raised portion, the second raised portion, and the third raised portion are formed as lead frame holders, bus bars, and pins, respectively. The method for fabricating the chip package structure disclosed in the present invention is that the lead frame is used as the crystal 4 package process for carrying H. The process of the chip package is to directly perform the wafer with the ready-made wire. The invention of the crystal # package structure is to first W = the wire and the encapsulation, and finally: two! 2 to form the wafer holder of the lead frame, the bus frame and the gold plate provided by the crystal # package structure manufacturing method It is the use of the 薄 process technology in the thin-film process, so that the gold will save the wafer holder, the busbar and the lead of the wire frame. Thus, the lead frame is caused by the direct use of the pattern sinking design. Among them - or a combination of any two of them is a sheet package structure towel, ^ (4) _ flow balance. Correction, in the crystal surface of the present invention, to improve the heat dissipation effect of the mask and the structure under the wafer holder under the wafer cover, and the money can be applied to the (10) package structure, although the package structure is The invention has been disclosed in the preferred embodiments as above, but it is not intended to limit the invention in any of the technical fields of the invention, which is not limited to 15 CN-9509009 22166 twf.d〇c/1.
