Description
最近、高性能MOSトランジスタを実現するため、チャネル領域にチャネルストレスを提供してキャリアの移動度(mobility)を向上させる方法が研究されている(特許文献1,2、非特許文献1,2)。
NMOSトランジスタ上に所定引張ストレスを有するライナ膜を形成し、ライナ膜上に第1層間絶縁膜としてO3-TEOS膜を形成した後、第1層間絶縁膜をFT-IR(Fourier Transform-Infrared Spectrometers)を用いて成分を分析した。引き続き、NMOSトランジスタ上に形成された第1層間絶縁膜をO3プラズマ処理した後、第1層間絶縁膜のFT-IRを用いて成分を分析した。その結果が図10に図示されている。
第1ないし第4NMOSトランジスタ上に所定引張ストレスを有するライナ膜を形成し、ライナ膜上に第1層間絶縁膜としてO3-TEOS膜を形成した後、第1層間絶縁膜のストレス大きさを各々測定した(As-Depo)。引き続き、第1ないし第4NMOSトランジスタ上に形成された第1層間絶縁膜を各々NH3プラズマ処理、O3プラズマ処理、N2プラズマ処理、O3プラズマ処理後、N2プラズマ処理して、第1層間絶縁膜のストレス大きさを各々測定した(Treatment)。その結果が、図11にともに図示されている。
シミュレーションプログラムにNMOSトランジスタ上に所定の引張ストレスを有するライナ膜を位置し、ライナ膜上に所定の引張ストレスを有した第1層間絶縁膜が位置するように設定した。その後、第1層間絶縁膜の厚さを変更させながら、それによる電子の移動度変化(mobility change)をシミュレーションした。その結果が、図12に図示されている。
