发明名称 Method for fabricating flip-attached and underfilled semiconductor devices
摘要 A semiconductor device (1700), which comprises a workpiece (1201) with an outline (1711) and a plurality of contact pads (1205) and further an external part (1701) with a plurality of terminal pads (1702). This part is spaced from the workpiece, and the terminal pads are aligned with the workpiece contact pads, respectively. A reflow element (1203) interconnects each of the contact pads with its respective terminal pad. Thermoplastic material (1204) 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 (1711) substantially in line with the outline of the workpiece, and fills the space (1707) 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.
