发明名称 Method for fabricating LOCOS isolation having a planar surface which includes having the polish stop layer at a lower level than the LOCOS formation
摘要 A method for fabricating LOCOS isolation having a planar surface. The method utilizes a polysilicon spacer to prevent bird beak. The method adds the steps of forming a polishing stop layer and removing said edge-protrusion portion of the local oxide by chemical mechanical polishing.
