Description
前記リードフレームのダイシング部には、前記ダイシングの幅よりも狭い幅で、前記ダイシング部の長手方向全体に連続してハーフエッチング部が形成され、該ハーフエッチング部内の前記コネクティングバーの交差部から、該交差部と隣り合う前記リード群のうち、該交差部の最も近くに位置する最端のリードまでの間にのみ連続して強度保持部が形成されていることを特徴とする。
図1は、本発明の一実施の形態に係るリードフレーム10の模式的な平面図を示し、単位リードフレームは4つのリード群14aに分かれて複数のリード14を有する。点線部は図3に示すようにリードフレーム10の一方の面を樹脂18で封止した後に、回転刃物で切断されるダイシングラインを示す。このダイシングラインに挟まれた部位がダイシングによって除去されるダイシング部である。
図2(a)は、図1中符号Bで示すリードフレーム10裏面のダイシング部A内のコネクティングバー11の交差部11a周辺の拡大平面図を示し、図2(b)はコネクティングバー11周辺の拡大断面図(図2(a)中のC−C断面)を示す。
図3は、本発明の一実施の形態に係るリードフレーム10を用いた半導体装置の断面図を示す。
なお、この図2(a)において、識別を容易にするためハーフエッチング部12にハッチングを施してある。
