Title: Dry etching method
Inventor: TOKASHIKI TAKESHI
IPC: H01L21/3065
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a method that does not depend on the crystal structure of titanium silicide and controls shapes in a highly anisotropic manner that prevents undercuts and side etch in worm holes. SOLUTION: A titanium silicide layer 5 formed on a silicon substrate 1 is dry etched in this method. A hard mask 8 is formed on the titanium silicide layer. Then, the titanium silicide layer 5 is etched using plasma of a mixed gas that is obtained by adding a methane gas and boron trichloride to chlorine or hydrogen bromide so that the sidewall of the etched layer is protected by methane. As a result, high anisotropic etching is secured regardless of the crystal structure of titanium silicide. Addition of the boron trichloride minimizes the difference of etch rates of titanium silicide and silicon nodule and prevents occurrence of etching residue.
