IPC: H01L21/768
Filed: 1985-11-20
Abstract: PURPOSE:To form a contacting hole of a diffused layer without fail by sequen tially forming an Si3N4 layer and an interlayer insulating film on an Si substrate formed with an element, and then thermally oxidizing to flatten the insulating film to prevent an oxide film from growing on the diffused layer. CONSTITUTION:An Si3N4 film 4 and a PSG film 11 are deposited on an element. The film 11 of an interinsulating layer film is deposited in the shape of copying the irregular surface of an element. To alleviate the irregular surface, it is pyrooxidized at 900 deg.C for 30min. Since an Si3N4 film 10 is interposed under the film 11, oxygen is not supplied to the substrate or SiO2 layer. Accordingly, new oxide film is not formed. Thus, the thicknesses of the SiO2 layers on N-type diffused layers 2, 3, 6, 7 are equal, and contacting holes 12, 13, 14, 15 of P-type, N-type diffused layers 2, 3, 6, 7 are formed in the same depth simultaneously by plasma etching.
