In this state, the semiconductor wafer is transferred from the opening to the Lu ϊ to 2 〇 10 ' to place the semiconductor wafer on the electrostatic chuck 203. The //electrostatic suction is followed by a state in which the ring member 220 and the head _ are lowered, and the gate 215 is formed to form a processing space 212 above the semiconductor wafer. The processing space 212 in the processing chamber 2〇1 is evacuated to a vacuum degree of the vacuum chamber 13 through the vent hole 13. Subsequent to the gas supply from the unillustrated, the predetermined flow rate is determined (the gas is engraved). This processing gas is supplied to the semiconductor wafer on the mounting table 202 in a shower form from the discharge hole 11 through the gas flow path 12 of the head 1〇〇. The pressure in the processing chamber 201 is maintained at a predetermined pressure, and then a high frequency power of a predetermined frequency, for example, 13 56 MHz, is applied to the mounting table 2〇2. As a result, a high-frequency electric field is generated between the head 100 as the one-pole and the mounting table 2〇2 as the lower head, and the etching gas system is decomposed and plasmaized. Further, for example, in the case where the processing space 212 = the plasma density in the peripheral portion is increased, the Icp plasma may be generated in the peripheral portion of the processing space by applying the high-frequency power to the lcp coil 24 根据 as necessary. With the plasma, a uniform etching process can be performed on the semiconductor wafer. 201216395 In the above etching process, since the processing gas from the head 1 is formed by the majority of the nozzles, the nozzles are not discharged and discharged from the lower portion of the processing chamber 201. The central part of the gas flows toward the peripheral part. Therefore, the processing gas of the body can be more uniform. Thereby, each part of the plasma conductor wafer conductor wafer can be uniformly homogenized U = can be half-in-average. Career. That is, the application of the surface power frequency power of the processing can be improved and the order of the half-_= reverse order is sent from the processing chamber 201 to the π / i, according to the plasma etching apparatus 200 of the present embodiment, because Aim = ==== plus average - chemical. In this way, the venting spurs of the semi-guided wafers can be smeared, because the venting is set from the nozzle 100, so there is no need to be placed as in the past, and the gantry is placed on the mounting table 202. An exhaust path is provided around the head 1〇0. Therefore, the I 2 of the processing chamber, that is, the outer diameter of the half wafer, can be set to be small above the processing t 201 , which can be performed from the portion closer to the R 1 ^ processing chamber. Exhaust, so it can be effectively vented. The electrode) 2〇m changes the head (upper electrode) 100 and the mounting table according to the position (the lower part is separated from the mounting table, and the head 100 can be easily moved up and down with a small amount of driving force, so that the device can be easily realized or installed. The cost is reduced. This is limited to the implementation of the above, Ke has a different meaning, in the electric form, although the description of the mounting table (the lower part of the 'if shouting power, but can also lie to the lower part σ A device of a type of a plurality of high-frequency powers of different frequencies, etc. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a longitudinal sectional view showing a 12 8 201216395 plasma-structured lion-bearing structure according to an embodiment of the present invention.
