Description
まず、真空チャンバ1の内部に設けられた支持具3の上に、処理対象となる半導体基板2を設置する。半導体基板2は、微細空間21を有している。微細空間21は、半導体基板2の外面に開口している必要はあるが、その口形、経路及び数等は任意である。図示の貫通孔である必要はないし、非貫通孔であってもよい。円筒、角筒状又は特許文献1に開示されているリング状の分離溝であってもよいし、図示の縦方向のみならず、これと直交する横方向に連なるような複雑な形状であってもよい。
次に、流し込み工程では、流動性絶縁物4を、微細空間21の開口している開口面から、微細空間21内に流し込む。この流し込み工程は、真空チャンバ1の内部の減圧雰囲気内で実行されることを基本とする。これにより、流動性絶縁物4が微細空間21内に真空吸入され、微細空間21の内部に絶縁物充填層41が生じることになる。
次に、加圧・硬化工程に移行する。加圧・硬化工程では、上述した流し込み工程により、微細空間21内に流動性絶縁物4を流し込んだ後、微細空間21内の絶縁物充填層41を、大気圧を超える強制外力F1を印加した状態で、冷却し硬化させる。強制外力F1は、硬化が完了するまで、継続して印加される。冷却は、基本的には室温中での徐冷であるが、室温よりも低い温度条件を設定してもよい。更に、時間経過とともに、連続的又は段階的に温度を低下させる冷却方法をとってもよい。

Claims (1)
- 半導体基板に設けられた微細空間内に絶縁物を充填する工程を含む方法であって、
前記微細空間の開口する前記半導体基板の一面側から、前記微細空間内に流動性絶縁物を充填し加圧したままで硬化させる工程を含み、
前記加圧は、機械的なプレス手段を用いたプレス圧、前記流動性絶縁物を前記微細空間内に充填する射出機の射出圧、転圧または遠心力の少なくとも一種によって与えられるものであり、
前記流動性絶縁物を硬化させて得られた絶縁物充填層に孔を設け、前記孔内に電極を形成する工程を含む、
方法。
