Abstract
The method of manufacturing a semiconductor device comprising: forming a wiring pattern on a substrate; forming a thermosetting resin layer on the substrate; aligning and adhering a semiconductor chip to the wiring pattern for electric connection via the thermosetting resin layer; and press-bonding an electrode of the chip onto the wiring pattern while the chip is being heated. During the press-bonding step, the substrate is cooled. By the cooling, the amount of thermal expansion of the substrate is suppressed and therefore comes closer to the thermal expansion of the chip. By mounting the chip on the substrate through the steps described above, the reliability of moisture resistance of the semiconductor device is greatly improved.
