ABSTRACT:
A lead frame according to this invention comprises: a semiconductor chip mounting part having an engagement hole formed on its one side; and a lead part including a supporting lead fit in said engagement hole of the semiconductor chip mounting part so as to support said semiconductor chip mounting part, said supporting lead being made of a thinner-walled material than that of the semiconductor chip mounting part and an outer lead arranged in parallel to said supporting lead. The supporting lead involves a fitting portion having a wider width than a lead width of the supporting lead and fit in said engagement hole of said semiconductor chip mounting part.
