大きくなりコスト的にも高価と成る問題があった。(FFG to be solved by the invention) However, as the integration of systems has progressed, many types of functions have come to be mixedly mounted on the same chip of a semiconductor wafer. For example, a microprocessor IC has a central processing unit (CPU) and a portion of memory (RAM, RO, etc.) in one chip.
M), an interface section, etc. are mounted, and within the chip, the pattern is physically divided into blocks such as a CPU section, a memory section, an interface section, etc. Furthermore, the pattern density in some parts of the memory is much higher than in other parts, and there is a large variation in pattern density within the same chip. This means that in the etching process of pattern formation, the etched area and density vary greatly depending on the location within the same chip. Here, the etching rate depends on the gas flow rate flowing into the processing chamber (1), that is, the activated reaction gas etchant, and when the gas flow rate is small, the rate is determined by the etchant supply rate. As the amount of etching increases, the amount of etchant becomes relatively insufficient. That is, a loading phenomenon occurs in which etching progresses quickly in areas where the etching area is small, and etching slows down in areas where the etching area is large. This causes the etching condition, especially the depth, to vary depending on the location due to the sparseness and density of the etching area within the same chip, resulting in a decrease in the reliability of the manufactured IC and the occurrence of defects. In order to reduce this loading effect, it is necessary to increase the flow rate of gas and increase the amount of etchant. For this reason, conventionally, the exhaust capacity of the exhaust system pump has been increased, but as the exhaust capacity of the pump increases, the physical size and ancillary equipment also increase, resulting in an increase in cost.

It is well known to those skilled in the art that an LCD is a liquid crystal display device, and refers to the etching process of the pattern forming the TPT circuit to drive this device. A plasma processing chamber (1) in which a plasma reaction is performed is a box-shaped airtight container made of aluminum, for example, whose inner surface is treated with alumite, which does not react with processing gas or the like. A lower electrode body (2) connected to a lifting mechanism (not shown) provided outside the chamber is provided on the lower side of the processing chamber (1) so as to be movable up and down. This lower electrode body (2) is a conductive plate made of, for example, aluminum, the surface of which is alumite-treated so as not to react with the processing gas, and is used for processing objects such as LCDs.
For example, it is formed into a rectangular flat plate shape that matches the shape of the glass substrate (3). Further, in the upper part of the processing chamber (1), a rectangular plate-shaped upper electrode base (4) that matches the shape of the object to be processed is provided, for example, in parallel and opposite to the lower electrode body (2). This upper electrode base (4) is made of aluminum and has its surface treated with alumite. On the lower surface of this upper electrode base (4), an upper electrode (5) made of, for example, amorphous carbon is attached to the upper electrode base (4). ) and are electrically connected to each other. A small space is formed between the upper electrode (5) and the upper electrode base (4), and a gas supply pipe (6) for introducing an etching reaction gas is provided in this space. The reactor gas, such as CCl4 and CI2, can be supplied to the space from the gas supply pipe (6) via a gas flow rate regulator (not shown), such as a mass flow controller. A plurality of baffles (not shown) having a plurality of openings are provided on the lower surface of the electrode body (4) in order to uniformly diffuse the reaction gas over the entire surface of the substrate (3). Furthermore, in order to excite the reaction gas, for example, high frequency electric power can be applied between the upper electrode base (4) and the lower electrode body (2). (7) is connected.

The CD glass substrates (3) are taken out one by one from a carrier (not shown) and, after positioning, are carried into a load lock chamber (not shown). The material is loaded from the load lock chamber onto the lower electrode body (2) in the processing chamber, and the distance between the upper electrode base 4) and the lower electrode body (2) is adjusted and set to a desired value. At this time, the gate valve (20) is placed in an oven state, the rotary pump (23) is used to perform rough evacuation, and the turbo molecular pump (22) is used to evacuate the inside of the processing chamber (1) to a high vacuum. The amount of vacuum evacuation is controlled by the opening/closing amount of the gate valve (20), and the pressure inside the processing chamber (1) is controlled and maintained at a desired pressure. For example, the inside of the processing chamber (1) is maintained at 1-3 Torr. While controlling the exhaust gas as shown in FIG.
00SCCM is introduced into a baffle (not shown) provided in the space of the upper electrode substrate (4) via the gas supply pipe (6), rectified uniformly with respect to the substrate (3), and flows to the LCD glass substrate. At the same time, high frequency electricity! From (7) to the frequency between the upper electrode base (5) and the lower electrode body (2), for example,
A high frequency power of 13.56 Mz is applied. By applying this high frequency power, the reaction gas is turned into plasma, and the LCD glass substrate is etched by the reaction gas turned into plasma.In order to reduce the loading effect, it is recommended to increase the amount of etchant. This increases the amount of reactant gas supplied from the gas supply pipe (6). However, since the pressure within the processing chamber (1) remains unchanged at the desired pressure for the process, increasing the amount of reactant gas supplied increases the amount of exhaust gas. That is, in order to increase the pumping capacity while keeping the vacuum pump's pumping characteristics unchanged, the pumping conductance of the pumping system must be reduced. Conventional conductance control valves are butterfly valves or double valves. For example, in a butterfly valve, as shown in Figure 2, a disc-shaped disc (30) installed inside the valve body is rotated by a drive device (31) such as a motor. Disk (
The exhaust conductance is adjusted and controlled by changing the rotation angle of the valve (30), but since the disk (30) is inside the valve body, the disk itself acts as an exhaust resistance and the maximum exhaust conductance becomes small in proportion to the outer diameter. On the other hand, as shown in Fig. 3, the gate valve has a drive device that moves the circular opening (41) at the joint with the piping from the fully open state to the fully open state, or vice versa. (
42) to increase or decrease the area of the opening (41) and control the exhaust conductance. Therefore, by using a gate valve, it is possible to control the entire diameter of the pipe from a so-called fully open state to a completely closed state.

を変化させて行なう。By matching the diameter of the exhaust port of an exhaust pump, such as a turbo-molecular pump, with the diameter of the opening (41) of the gate valve, the exhaust route can be connected with piping of the same diameter, and the maximum exhaust conductance can be obtained. By using the gate valve of the present invention, the maximum exhaust conductance increases by about 50%, which is improved compared to when a conventional butterfly valve is used in the exhaust system. The gate valve is controlled by detecting the pressure inside the processing chamber (1), and based on this detection signal, the driving device (42) is controlled by PID control by a controller configured with a microprocessor (not shown), etc.
This is done by driving the gate plate (43) and changing the area of the opening (41).
