Description
本発明は、概略的には、半導体装置に関するものであり、より詳細には、性能向上のためトランジスタにおける応力を調整する装置および方法に関するものである。
半導体装置は、コンピュータおよび携帯電話など、多くの電子機器において使用されている。装置を小型化および高速化し続けることが、半導体産業におけるひとつの目標である。各構成間の物理的距離が小さくなるため、装置は小さければ小さいほどその処理速度は速くなる。また、銅のような高導電率の物質は、アルミニウムのような低伝導率の物質に取り代わられつつある。さらに、課題の一つとして、電子や正孔などの半導体キャリアの移動度の向上が挙げられる。
本発明の好ましい形態である、半導体装置に歪領域を形成する方法および構造を用いることによって、上記の問題点などは普遍的に解決または回避され、技術的な利点を普遍的に達成することができる。
各図面において対応する番号や記号は、特に指定する場合を除いて、通常、同じ部材を表している。図面は好適な実施形態の該当部分を明確に表すためのものであって、実際の縮尺とは必ずしも一致しない。いくつかの実施形態をさらに明瞭に説明するために、同じ構造、材料、工程の変形については、部材番号の後にアルファベットを付している。
