Patent ID: 7741708

Claim:
A semiconductor device in which a plurality of semiconductor chips are mounted on a lead frame and seal portions are provided so as to cover said plurality of semiconductor chips and required portions of said lead frame to be covered, said plurality of semiconductor chips being divided into a first group of semiconductor chips and a second group of semiconductor chips wherein both groups of semiconductor chips are respectively mounted on one and the other sides of said lead frame in its width direction at a distance from each other, said seal portions being comprised of first and second resin-seal portions wherein said first and second groups of semiconductor chips are respectively covered along with the required portions of said lead frame to be covered, said first and second resin-seal portions being mechanically coupled with each other by coupling portions, wherein a gap is formed between said first and second resin-seal portions and the outer lead portions of leads connected to circuits within said first resin-seal portion and the outer lead portions of leads connected to circuits within said second resin-seal portion are drawn out through said gap between said first and second resin-seal portions as lead terminals, a plurality of leads that form part of said lead frame comprises said coupling portions, wherein both ends of each of said plurality of leads comprising said coupling portions are buried in said first resin-seal portion and in said second resin-seal portion, and coupling resin-molded portions which cover said plurality of leads comprising said coupling portions are formed so as to bridge said first resin-seal portion and said second resin-seal portion so that said first and second resin-sealed portions are mechanically coupled with each other also by said coupling resin-seal portions.
