Inventor: PARK SEONG YONG
IPC: H01L21/76
Filed: 1999-12-24
Abstract: PURPOSE: A method for manufacturing an isolation layer of a semiconductor device is provided to increase yield of conventional cerica-based slurry by uniformly guaranteeing the thickness of a pad nitride layer, and to prevent a fail of the device by performing a shallow trench isolation(STI) process to guarantee more margin in a subsequent process. CONSTITUTION: A pad oxide layer(22) and a pad nitride layer(23) are sequentially formed on a semiconductor substrate(21) and patterned. The semiconductor substrate is etched to form a trench by using the patterned pad nitride layer and pad oxide layer as a mask. After a silicon-rich high density plasma-undoped silicate glass(HDP-USG) layer(24) is deposited by a minimum thickness to bury the trench, a spin-on-glass(SOG) layer(25) is formed. The SOG layer and the silicon-rich HDP-USG layer are polished by a chemical mechanical polishing(CMP) process using cerica-based slurry. The pad nitride layer and the pad oxide layer are eliminated.
