Abstract
A method of manufacturing a semiconductor device is disclosed. The method includes depositing an O3-TEOS oxide film having a good flow-like property under a high adhesive force in order to prevent degradation in the characteristic of the surface of a lower insulating film made of a PE-TEOS oxide film and generation of defect due to the topology difference. Therefore, the disclosed method can improve the electrical characteristic of a semiconductor device and the manufacturing yield.
