Title: Plasma etching system and method
Inventor: TOMITA KAZUISHI
IPC: H01L21/302
Filed: 1993-10-12
Abstract: PURPOSE:To suppress plasma polymerization reaction in a thin hole and prevent polymer from being adhered to the peripheral wall of the thin hole by controlling a gas supply means in a plasma etching system and speeding up the flow rate of gas through the thin hole of a shower electrode. CONSTITUTION:A wafer W is carried into a treatment chamber 1 and is sucked and retained on a chuck electrode 61. Ar gas, CF4 gas, and CHF3 gas are introduced into the treatment chamber 1 via the shower electrode 3 and at the same time the inside of the treatment chamber 1 is evacuated. Then, a high-frequency power is applied between a cathode plate 54 and the chuck electrode 61, thus generating discharge plasma, allowing gas plasma to react with the wafer W, and hence etching a wafer surface. In this case, since the flow rate of gas passing through a thin hole 55 is set to 100Km/hour or faster, gas is supplied to the thin hole 55 so that a mass flow rate is equal to or higher than 620Kg/m<2>/hour, thus preventing polymer from being adhered to the gas emission hole of the shower electrode 3 for a long-term continuous use.
