Description
SiGe層を成長させるためのシリコン基板のリセスは、一般的に使用されるKOHや沸硝酸をエッチング液とするウエットエッチングでも形成することができる。しかし、これらのエッチング液を使用したのでは、特許文献1の図1に示されるように、上記のリセスの側面が緩やかな曲面となるため、リセスの形状を制御するのが困難でとなる。そのため、リセスの側面の形状が素子毎にばらついて、MOSトランジスタの特性が素子毎に変動する恐れがある。
図1は、シリコンと二酸化シリコンに対するTMAH溶液のエッチング選択性を調査するために使用されたサンプルの断面図である。これらのサンプルのうち、サンプルS1は次のようにして作製された。
上記した図2、図3の実験では、ポリシリコン層3に対して不純物を導入しなかったが、ポリシリコン層3のエッチングレートが不純物濃度に依存すると推測される。この点を確かめるため、本願発明者は次のような実験を行った。
次に、第1実施形態で明らかとなったTMAH溶液と有機アルカリ溶液のエッチング特性を利用してシリコン基板にリセスを形成し、そのリセス内のSiGe層をソース/ドレインとするMOSトランジスタを作製する方法について説明する。
実施例ではゲート加工後に薄いスペーサを形成せずにエクステンションおよびポケット形成を行うプロセスで述べるが、エクステンションとゲートの最適なオーバーラップを形成するため5〜20nmの薄いスペーサを形成した後エクステンションおよびポケット注入を行う方法も可能である。また、nMOSあるいはpMOSのどちらか一方にのみスペーサを形成させる方法も可能である。スペーサの膜構成、形状には頓着せず、スペーサとしての機能を持つものであれば可能である。
次に、本発明の第3実施形態に係る半導体装置の製造方法について説明する。
次に、本発明の第4実施形態に係る半導体装置の製造方法について説明する。
次に、本発明の第5実施形態に係る半導体装置の製造方法について説明する。
次に、本発明の第6実施形態に係る半導体装置の製造方法について説明する。
次に、本発明の第7実施形態に係る半導体装置の製造方法について説明する。
図17(a)、(b)は、本発明の第8実施形態に係る半導体装置の製造途中の断面図であり、図18はその平面図である。これらの図において、第2〜第6実施形態で既に説明した要素にはこれらの実施形態と同じ符号を付し、以下ではその説明を省略する。
図19は、本発明の第9実施形態に係る半導体装置の製造途中の断面図であり、図20はその平面図である。これらの図において、第8実施形態で既に説明した要素にはこれらの実施形態と同じ符号を付し、以下ではその説明を省略する。
次に、本発明の第10実施形態に係る半導体装置の評価方法について説明する。
次に、本発明の第11実施形態に係る半導体装置の評価方法について説明する。
