Claims
- 1. A semiconductor device comprising:
- (a) a rectangular semiconductor pellet having first and second major surfaces opposed to each other, and said first major surface has first, second, third and fourth sides;
- (b) a plurality of bonding pads arranged on said first major surface and along said third and fourth sides opposed to each other;
- (c) a first, second, third and fourth leads each having an inner portion, an end portion and an outer portion, the inner portion extending over said first major surface;
- (d) an insulating sheet inserted between and bonded to said end portions of said leads and said first major surface of said semiconductor pellet;
- (e) a plurality of bonding wires each electrically connected between each of said end portions of said leads and each of said bonding pads; and
- (f) a resin sealing means encapsulating said semiconductor pellet, said insulating sheet, and said inner portions of said leads, wherein said first lead intersects said first side and extends to said third side, said second lead intersects said first side and extends to said fourth side, said third lead intersects said second side and extends to said third side and said fourth lead intersects said second side and extends to said fourth side.
- 2. A semiconductor device according to claim 1, wherein said first major surface is a circuit-forming face of said semiconductor pellet.
- 3. A semiconductor device according to claim 2, wherein said insulating sheet is made of silicon rubber.
- 4. A semiconductor device according to claim 2, wherein said insulating sheet is made of a polyimide film.
- 5. A semiconductor device according to claim 2, wherein said insulating sheet is made of an organic material.
- 6. A semiconductor device comprising:
- (a) a semiconductor pellet having first and second oblong major surfaces opposed to each other;
- (b) a plurality of bonding pads arranged along shorter sides of said first oblong major surface and disposed on said first oblong major surface;
- (c) a plurality of leads each having an inner portion, an outer portion and an end portion, said inner portion entering from a longer side of said pellet and said end portion of said inner portion extending to one of said bonding pads;
- (d) an insulating sheet inserted between and bonded to said inner portions of said leads and said first major surface of said semiconductor pellet;
- (e) a plurality of bonding wires each electrically connected between each of said end portions of said inner portions and said bonding pads; and
- (f) a resin sealing means sealing said semiconductor pellet, said insulating sheet, said bonding wires and said inner portions of the leads.
- 7. A semiconductor device according to claim 6, wherein said first major surface is a circuit-forming face of said semiconductor pellet.
- 8. A semiconductor device according to claim 7, wherein said insulating sheet is made of silicon rubber.
- 9. A semiconductor device according to claim 7, wherein said insulating sheet is made of polyimide film.
- 10. A semiconductor device according to claim 7, wherein said insulating sheet is made of an organic material.
- 11. A semiconductor device according to claim 6, wherein said resin sealing means has an oblong shape in plan view, and longer sides of said resin sealing means correspond to said longer sides of said semiconductor pellet.
- 12. A semiconductor device according to claim 11, wherein said outer portions of the leads only protrude from said longer sides of said resin sealing means.
