Title: Method for forming shallow trench isolation of semiconductor element
Inventor: KIM CHANG GYU
IPC: H01L21/76
Filed: 2001-01-12
Abstract: PURPOSE: A method for forming a shallow trench isolation of a semiconductor device is provided to minimize the CMP process time and to remove the damage due to the CMP process through two wet etching processes. CONSTITUTION: A pad oxide film(103) is grown by thermal oxidizing the silicon substrate(101) and a nitride film(105) is deposited by a CVD method. A trench mask pattern is formed on a device isolation region by etching the nitride film and the pad oxide film. An oxide film is formed by the thermal oxidation. The trench is completely buried by depositing an insulation film(107) through an HDP(High Density Plasma) CVD method. A sacrificial film(109) for the wet etching is formed by using a nitride material. The CMP process is carried out until the insulation film is exposed. The first wet etching process is carried out in order to remove the insulation film on the active region. The nitride film is completely removed by carrying out the nitride wet etching process.
