IPC: H01L21/28
Filed: 1985-10-11
Abstract: PURPOSE:To form a precious metal electrode of excellent pattern accuracy by a method wherein the thickness of a resist is limited taking into considera tion the thickness of a metal film. CONSTITUTION:An Au film 4 is coated on the whole surface of the AuGe/Ni region 2 and the silicon oxide film region 3 formed on a GaAs substrate 1 by performing a sputtering.

The thinner the resist becomes, the more the degree of preciseness of working increases, and it is necessary that the resist has the thickness of 40% or more of the Au film. Also, as the etching speed of Pt is about 1.5 times that of the positive resist, the thickness of the resist of 40-100% of the thickness of a metal film is considered suitable when an ion milling is performed on a precious metal film. Then, after a pattern is formed on the positive resist, an ion milling is performed using said resist as a mask, and the Au electrode 8 having the desired pattern can be formed in an excellent precise manner when the resist is removed.
