Title: Method of forming isolation in semiconductor device
Inventor: HAN SANG GYU
IPC: H01L21/76
Filed: 2000-07-31
Abstract: PURPOSE: A method for forming an isolation film of a semiconductor device is provided, which prevents an erosion of a trench edge causing incomplete operation of the device and improves the quality of a gate oxide. CONSTITUTION: According to the method, a gate oxide and a polysilicon is formed on a semiconductor substrate(21) and then a nitride film is formed on the polysilicon. Because the semiconductor substrate is a bare silicon and the gate oxide is formed directly on the intrinsic bare silicon, the quality of the gate oxide is improved. And an isolation mask is formed on the nitride film. Using the isolation mask, a surface of the semiconductor substrate where an isolation film is formed is revealed by etching the nitride film and the polysilicon and the gate oxide using the isolation mask. Then, a trench is formed by etching the semiconductor substrate using the etched nitride film and the polysilicon and the gate oxide after removing the isolation mask. Then a high density plasma oxide(HDP oxide) is formed. After forming an isolation film(26b) by a CMP(Chemical Mechanical Polishing) of the HDP oxide until the bottom nitride film is revealed, the nitride film is revealed. After performing a gate patterning on the revealed polysilicon by revealing the nitride film, a gate electrode(23b) is formed by selectively etching the polysilicon and the gate oxide.
