摘要:
A semiconductor device, which comprises a workpiece with an outline and a plurality of contact pads and further an external part with a plurality of terminal pads. This part is spaced from the workpiece and the terminal pads are aligned with the workpiece contact pads, respectively. A reflow element interconnects each of the contact pads with its respective terminal pad. Thermoplastic material fills the space between the workpiece and the part; this material adheres to the workpiece, the part and the reflow elements. Further, the material has an outline substantially in line with the outline of the workpiece, and fills the space substantially without voids. Due to the thermoplastic character of the filling material, the finished device can be reworked, when the temperature range for reflowing the reflow elements is reached.

A process for manufacturing a wafer dicing/bonding sheet of the present invention comprises a soft film, a pressure sensitive adhesive layer formed on the soft film, a processing film for polyimide type resin composed of a heat resistant resin which has been formed on the pressure sensitive adhesive layer and a polyimide adhesive layer formed on the processing film. It is preferred that the processing film be a polyethylene naphthalate film whose surface has been subjected to an alkyd release treatment. The present invention facilitates expansion to be conducted after the wafer dicing.
