Abstract
Description
図1,2,3は順に、本発明の半導体装置の製造方法を説明した縦断面図であり、図3は製造された半導体装置も示している。
本発明者等は、図1,2で示す製造方法でコレクタリードフレームと半導体素子を接合してなる積層体を試作した。具体的には、実施例として、図2で示す積層体を製作し、比較例として、コレクタリードフレームとSn系はんだ層の間にNi3Sn4もしくは(Ni,Cu)3Sn4の金属間化合物層のみが介在する積層体を製作した。
Claims (1)
- 半導体装置を構成する複数の部品のうち、Sn系はんだ層にて第一部品と第二部品を接続して半導体装置を製造する半導体装置の製造方法であって、
少なくとも前記第一部品において、前記Sn系はんだ層が形成される表面にはNi被膜が形成されており、
重力方向の下方から順に、前記第一部品、第一Cu層、Sn系はんだ材料、前記第二部品を積層し、ここで、該第一Cu層は該Sn系はんだ材料の平面寸法よりも小さな平面寸法を有しており、
加熱処理することにより、前記Sn系はんだ材料が溶融し、凝固してなるSn系はんだ層を形成し、
前記Sn系はんだ層と前記第一部品の間において、中央側には、Cu6Sn5もしくは(Cu,Ni)6Sn5の金属間化合物層を形成し、外周側には、Ni3Sn4もしくは(Ni,Cu)3Sn4の金属間化合物層を形成して前記第一部品と前記第二部品を接続し、全体を樹脂モールドして半導体装置を製造する半導体装置の製造方法。
