| 摘要 |
The invention is directed to enhancement of reliability and a yield of a semiconductor device by a method of manufacturing the semiconductor device with a supporting body without making the process complex. A second insulation film, a semiconductor substrate, a first insulation film, and a passivation film are etched and removed in this order using a resist layer or a protection layer as a mask. By this etching, an adhesive layer is partially exposed in an opening. At this time, a number of semiconductor devices are separated in individual semiconductor dies. Then, as shown in FIG. 10, a solvent (e.g. alcohol or acetone) is supplied to the exposed adhesive layer through the opening to gradually reduce its adhesion and thereby a supporting body is removed from the semiconductor substrate. |
