摘要
Abstract
MMT (modified magnetron typed) plasma nitridation and NO anneal are used to treat ultra-thin gate oxides in MOSFETs (metal-oxide-semiconductor field effect transistors). Dual-peak and single-peak N distributions are formed after nitridation. The dual-peak N distribution shows excellent electrical properties and superior reliability in terms of drain current,channel carrier mobility, and TDDB characteristics. The results indicate a means to extend silicon oxynitride as a promising gate dielectric for developing ultralarge scale integrated (ULSI) technology.关键词
