Description
先ず、図4において、図4(a)はシート010に対してストリップ切断部011でストリップ単位で第1次エッチングを行うことを示している。
第1実施形態による本発明は、段階的なエッチングを適用してアンダーカット現象を最小化させることができるものである。
図8(d)で感光性物質42に対する第2次露光及び現像を行う(ST14)。
第2実施形態による本発明は、基本的な回路及び半導体チップ能動素子の埋め込みのためのエッチング工程後に選択的に表面処理層を形成し、酸化防止処理をすることにより、アンダーカット現象のために発生するパッド部の消失又はサイズ縮小現象を効果的に防止することができる。
また、図15(d)は図15(b)と(c)についての一構成例を示す図である。
第3実施形態による本発明は、パターン形成のためにストリップが切断された形態の第1次エッチング品を用いることなく、一枚板のエッチング品を使用するため位置合せが容易であり、入出力端子の微細パターンの形成が可能であり、且つアンダーカット現象が発生せず、工程上への適用が容易であり、工程速度も速い製造方法を提供するためのものである。
次いでストリップ別に切断を実施する(ST45)。この際、パンチング、ルーティング、レーザカッティング、リソグラフィーなどを用いてストリップ別に切断工程を進める。
また、モールディング後に下部を完全にエッチングして独立的な入出力端子の形成のための下部エッチングを進める(ST47)。
また、本実施形態の発明は、パターン幅当りの位置合せバイアスが0.11以下((位置合せバイアス38.67μm)/(パターンの幅350μm)=0.11048)となるようにする。
