Description
エピタキシャル層26表面を熱酸化する。その後,N2ガスで約1180℃の熱処理を2時間程度加えて分離領域を再度拡散させる。この熱処理により、第2分離領域32がシリコン表面側に拡散されるので、その分後述の第3分離領域33を浅く拡散させることができる。従って、第3分離領域33の横方向拡散を抑制でき、第3分離領域33の表面占有面積を縮小可能である。この結果集積度を向上できる。そして、シリコン酸化膜をフォトエッチして選択マスクとする。その後、第3分離領域33を形成するボロン(B)を拡散させる。第1と第2のエピタキシャル層25、26は、両者を完全に貫通するP+型分離領域27によってフォトダイオード21を形成する第1の島領域28と、容量素子22を形成する第2の島領域29と、NPNトランジスタ23を形成する第3の島領域30とに電気的に分離される。そしてベースにイオン注入し、N2ガスで約1100℃の熱処理を1時間程度加えてベース拡散を行ってNPNトランジスタのベース領域42を形成する。
