Title: Manufacture of semiconductor device
Inventor: HAYASHI KAZUO
IPC: H01L21/302
Filed: 1987-08-19
Abstract: PURPOSE:To carry out reactive ion etching which gives less damages to a semiconductor substrate and has excellent unisotropy and facilitate precision work by a method wherein first etching is carried out with CF4/H2 gas and then etching with CF4/O2 system gas is carried out. CONSTITUTION:An SiN film 2 formed on a semiconductor substrate 1 is etched by using a resist pattern composed of a patterned resist film 3 as a mask. At that time, first etching is carried out with CF4/H2 gas and remaining parts are etched with CF4/O2 gas. As the CF4/H2 gas has excellent selectivity and unisotropy with the photoresist 3, almost no film shortage of the resist 3 occurs and unisotropic etching with a vertical cross section can be performed. With this constitution, precision work can be achieved.
