Title: Manufacture of semiconductor device
Inventor: MORI HAJIME
IPC: H01L21/302
Filed: 1992-09-28
Abstract: PURPOSE:To prevent a deterioration in withstand voltage or damage of an oxide film in a dry etching process. CONSTITUTION:Reactant gas is led into an etching chamber 1, and high frequency power is gradually applied to a MOS-type transistor. Then high chuck voltage is gradually applied to an electrostatic generating sheet 4 to have a silicon substrate 7 tightly adhered to a lower electrode 2 by electrostatic attraction. As a result, since chuck voltage for electrostatic attraction will be applied to the silicon substrate 7 while plasma is discharging in an electrically stable state, static electricity generated by the application of chuck voltage is neutralized by the plasma. Therefore it is possible to prevent an electric stress applied to an oxide film 8.
