Summary: | PURPOSE:To embody uniform and high speed etching and high throughput required for dry etching for the formation of via hole electrodes for GaAs group devices in terms of a dry etching device which adopts an RIE system. CONSTITUTION:Around a cathode electrode and an anode electrode 1, there is installed a disk-shaped and mesh-like plasma sealing electrode 2 having a grand potential in order to contain the plasma locally. Furthermore, there is installed a wafer bringing-in and bringing-out passage so as to load and unload a workpiece or wafer 112 to the cathode electrode in continuous mode. What is more, there is installed a magnetic field/electrode supply system 8 on the way of the passage 3. |
