Abstract
Description
まず、図3(a)に示すような基板1を用意した。基板1としては、厚さ200μmで、第一の面2と、その反対側の面である第二の面3とを有し、第一の面及び第二の面の結晶方位は(100)のシリコン基板を用いた。
実施例1で、第一の層を横方向に30.0μm四方、縦方向に0.5μmの大きさで形成したのに対し、実施例2では、第一の層を横方向に30.0μm四方、縦方向に0.1μmの大きさで形成した。これに伴い、第一の層を覆う第二の層の大きさも変更した。これ以外の条件は実施例1と同様とし、基板の加工を行った。この工程は、図4(a)、(b)、(c)に示す通りである。
実施例1で、第一の層を横方向に30.0μm四方、縦方向に0.5μmの大きさで形成したのに対し、実施例3では、第一の層を横方向に27.6μm四方、縦方向に0.5μmの大きさで形成した。これに伴い、第一の層を覆う第二の層の大きさも変更した。これ以外の条件は実施例1と同様とし、基板の加工を行った。この工程は、図5(a)、(b)、(c)に示す通りである。
実施例1で、第一の層を設けたのに対し、比較例1では第一の層を設けなかった。これ以外の条件は実施例1と同様とし、基板の加工を行った。
比較例1で形成した第二の層を、基板の第一の面に沿うように、第一の面上に形成した。即ち、第二の層と基板の第一の面とを平行に形成した。
