Patent ID: 7520052

Claim:
A method of manufacturing a semiconductor device; comprising: providing a substrate with a first surface and a second surface; disposing a plurality of semiconductor elements on the first surface of the substrate; placing the second surface opposite to the first surface of the substrate on a supporting member; dispensing a liquid resin at a temperature to each of the semiconductor elements to cover at least a portion of each semiconductor element; the liquid resin having a glass transition temperature in the range of 100-160° C., a coefficient of thermal expansion in the temperature region below the glass transition temperature in the range of 20-30 ppm, a coefficient of thermal expansion in the temperature region above the glass transition temperature in the range of 80-120 ppm, a longitudinal modulus in the temperature region below the glass transition temperature in the range of 1-20 GPa, and a longitudinal modulus in the temperature region above the glass transition temperature in the range of 0.1-1.0 GPa; providing a mold part having a plurality of recesses formed in one surface; pressing the mold part onto the supporting part; providing thermal energy to mold the liquid resin and each semiconductor element within each said recess at a temperature higher than the dispensing temperature; and releasing the recesses of the mold part from the substrate.
