Method for forming a nitridized interface on a semiconductor substrate

摘要

A surface treatment method for forming a fluorine-doped nitridized interface on a semiconductor substrate. The fluorine-doped nitridized interface may be formed using an ammonia plasma CVD process having a treatment gas doped with a fluorine component, such as carbon hexafluorine. The method may be employed as part of a LOCOS-based processing scheme in the manufacture of MOS semiconductor devices, such as DRAM devices.
