Title: Patterning method for silicon material layer
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/302
Filed: 1994-10-18
Abstract: PURPOSE: To provide a patterning process for silicon material layers, including trench etching to a single-crystal silicon substrate, wherein the selectivity to a resist mask is improved, wherein excellent anisotropy is obtained, and wherein less particle contamination is caused. CONSTITUTION: Plasma etching is performed using a gas mixture of a gas of organic compound containing C-O bonds, such as alcohol, and a halogen gas. A sidewall protective film 5 formed during this plasma etching is composed mainly of decomposition products from a resist mask 4. The protective film has a less halogen content and has taken in C-O bonds; therefore, it is excellent in resistance to ion bombardment and radical attack. A sulfuric compound may be used together to form the sidewall protective film by adding sulfur halide gas. Thus the enhanced quality of the sidewall protective film reduces the amount of its deposition, and makes possible anisotropic etching with reduced energy of incident ion. This prevents particle contamination and the reduction of resist masks.
