IPC: H01L21/76
Filed: 1990-03-23
Abstract: PURPOSE:To form a field oxide film having a short bird's beak when an oxide film is formed on a semiconductor substrate with a nitride film as a mask by directly forming a nitride film, or forming the nitride film after forming a pattern with a material which can be selectively etched with respect to the oxide film, and performing etching until the pattern is exposed. CONSTITUTION:The ions of molecules containing nitrogen atoms and at least one kind of atoms whose atomic weight is lager than that of nitrogen, e.g. the ions of SiNx, are implanted into an Si substrate 1. Thus an SiNx film 2 is directly formed on the substrate 1. Or the surface of the substrate 1 is inversely sputtered and cleaned, and molecules containing nitrogen, e.g. SiNx, are deposited and patterned. The substrate undergoes thermal oxidation. Or an SiO2 film 5 is formed on the substrate 1 and pattered. Then, a pad SiO2 film 6 is formed between the SiO2 films 5, the SiNx film 2 is formed on the entire surface and an SOG film 7 is formed on the film 2. The SOG film 7 is etched back, and the SiNx film 2 is exposed. Then, the SiNx film 2 is etched back until the SiO2 film 5 is exposed. Thereafter, the SOG film 7, the SiO2 film 5 and the SiO2 film 6 are removed, and the substrate 1 undergoes thermal oxidation.
