Filed: 2001-12-19
Abstract: PURPOSE: A method for manufacturing semiconductor devices is provided to improve reliability for mounting a semiconductor device and to reduce manufacturing costs, since a first substrate is formed mainly by an insulating material equal in thermal expansion coefficient to a second substrate as a mounting substrate. CONSTITUTION: With the temperature of lower and upper mold halves(16a,16b) set at 175°C, back side of a strip substrate(12) is chucked by vacuum suction holes(17), causing the strip substrate(12) and molding surface of the lower mold half(16a) to come into close contact with each other. At this time, the strip substrate(12) can be vacuum-sucked to a satisfactory extent because the strip substrate is extremely thin as noted previously. Thus, the back side of the strip substrate(12) is subjected to vacuum suction in the sealing treatment, whereby the warp, etc. caused by the foregoing heat treatment can be further diminished. Therefore, even if the plane area of the strip substrate(12) further increases to meet a demand for increase in the number of products to be obtained, or even if the thickness of the strip substrate(12) becomes still smaller to meet a demand for the reduction in wall thickness of the semiconductor device, it is possible to effect resin-sealing while ensuring flatness of the whole of the strip substrate(12).
