Description
図1は、半導体ウェハの外観模式図であり、図2は、半導体ウェハの構造例を示す上面模式図であり、半導体ウェハのX軸とX軸に直交するY軸とを含むX-Y平面の一部を示す。図3は、半導体ウェハの構造例を示す断面模式図であり、X軸とX軸およびY軸に直交するZ軸とを含むX-Z断面の一部を示す。
半導体ウェハ1は、例えば触媒アシストエッチング(Metal-assisted Chemical Etching:MACE)を用いて製造することができる。MACEは、基板の表面に触媒層を形成した基板を薬液に浸漬することで、触媒層に接する領域のみを略垂直にエッチングする技術である。
図9は、半導体ウェハ1の他の製造方法例を説明するための図である。本例では、半導体ウェハ1の(110)面に沿って表面10aを形成するとともに、表面10aの上にマスク層3を形成し、半導体ウェハ1の(111)面に沿って半導体ウェハ1をエッチングすることにより溝11を形成する。
図10ないし図14は、半導体ウェハ1の他の構造例を示す断面模式図である。なお、上記半導体ウェハ1の説明と同じ部分については上記説明を適宜援用することができる。
図15は、半導体ウェハ1を用いた半導体装置の構造例を示す断面模式図である。図15に示す半導体装置は、半導体ウェハ1に設けられた膜5を具備する。膜5は、例えばCVD装置等の成膜装置を用いて表面10aの上に形成される。膜5は、例えば成膜評価するための下地膜、例えばエッチングするためのエッチング対象膜として機能する。膜5の厚さは、用途に応じて設定される。なお、膜5は積層膜であってもよく、図13に示す保護膜4b上に形成してもよい。
実施形態の半導体ウェハの使用方法例として、半導体装置の製造工程において上記半導体ウェハ1をダミーウェハとして使用する例について図16ないし図19を用いて説明する。
