IPC: H05H1/46
Filed: 1993-09-10
Abstract: PURPOSE:To provide a plasma vapor growth device which improves the sealability of reactive gases between electrodes and the uniformity of an electric field intensity distribution. CONSTITUTION:This plasma vapor growth device has a reaction vessel 1, a heater-contg. grounding electrode 3, a high-frequency electrode 9 for blowing off the reactive gases and a high-frequency power source 8. The current leakage by plasma ion conduction is prevented by shutting off the space between the reaction vessel 1 grounded to the high-frequency electrode 9 and a metallic part of an internal device by an insulating separator 4. The insulating spacing by the insulating separator 4 and the space described above is widened to decrease a floating electrostatic capacity, by which the distortion of the electric field intensity distribution on the heater-contg. grounding electrode 3 is maintained small even if the spacing between both electrodes described above is narrowed. The confining of the reactive gases between both electrodes is improved by confining the spacing between the heater-contg. grounding electrode 3 and the high-frequency electrode 9.
