Claims
- 1. A semiconductor device comprising a semiconductor chip, a tape for mounting said semiconductor chip thereto, an adhesive resin layer interposed between said semiconductor chip and said tape, and solder balls passing through ball mounting holes arranged on said tape, characterized in that said tape and said adhesive resin layer have at least one vapor escaping hole, in addition to said ball mounting holes, extending through said tape and reaching said adhesive resin layer.
- 2. A semiconductor device according to claim 1, further comprising a sealing resin for sealing said semiconductor chip, said adhesive resin layer comprising a die bonding material for fixing said semiconductor chip to said tape.
- 3. A semiconductor device according to claim 1, further comprising a sealing resin for sealing said semiconductor chip, said adhesive resin layer comprising a buffer material for reducing a stress occurring due to the difference in coefficient of thermal expansion between said semiconductor chip and said tape, and a die bonding material for fixing said semiconductor chip to said tape through said buffer.
- 4. A semiconductor device according to claim 1, characterized in that said semiconductor chip is connected to said tape by protruded electrodes, and said adhesive resin layer is made of an under-filling material filled between said semiconductor chip and said tape.
- 5. A semiconductor device according to claim 1, characterized in that said tape is a FPC tape.
