Title: Dry etching method
Inventor: MATSUTANI TETSUYA
IPC: H01L21/336
Filed: 2000-07-06
Abstract: PROBLEM TO BE SOLVED: To solve the problems that are raised when SF6 is used as a tungsten etching gas at the time of forming by dry etching a poly-metal structure which is formed by laminating a metal on polysilicon and in which the metal is used as a gate electrode, namely, the etching rate is not able to be controlled, because the tungsten used in the poly-metal structure in the form of a metallic film is thin in thickness and, accordingly, the etching rate of the tungsten film is too fast, and the gate electrode is broken through by the dry etching, because no etching selectivity is obtained between the tungsten film and polysilicon underlying the tungsten film. SOLUTION: At the time of etching the tungsten film, a CF-based gas is used instead of the SF6. III addition, in order to raise the etching selectivity between the tungsten film and polysilicon underlying the tungsten film, oxygen gas is added to the CF-based gas at a flow ratio of 10-50%.
