Title: Method for forming trench element isolation film by using annealing
Inventor: KO SHUCHIN
IPC: H01L21/8234
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent a gate oxide film from degradating in performance at a following gate oxide film forming step by annealing the resultant products after CMP for a trench element isolation film. SOLUTION: To reduce an excessive stress which is generated by a primary stress caused by a trench burying substance layer and in a first annealing process, a trench 46 is buried by a compound film which is comprised of a first oxide film 48 having a stretching stress property and of a second oxide film 50 having a compressing stress property. The second oxide film 50 is flattened until an insulating film 44 is exposed and an element isolation film 52 which is buried in the trench is formed. Second annealing for resultant products on which the element isolation film 52 is formed is made at a predetermined temperature and under the atmosphere, and the contaminating substance which exists at the boundary between a semiconductor substrate 40 and a pad oxide film 42 is eliminated by deffusing outside.  Thus, a gate oxide film is prevented from degradating in property at a following gate oxide film forming step.
