Abstract:
1. A method for manufacturing a semiconductor device, the method comprising the steps of: forming a plurality of concave portions on a front surface of a first substrate; forming a wiring extending from the inside of the plural concave portions to a rear surface of the first substrate; mounting a semiconductor element on each of the plural concave portions; encapsulating the semiconductor element by bonding the front surface of the first substrate to a second substrate made of a material different from a material of the first substrate; forming a first groove in the first substrate and a second groove in the second substrate; and individualizing the semiconductor device by cleaving a portion between the first groove and the second groove so as to individualize the semiconductor device; wherein the individualized semiconductor device includes at least one of the concave portions on which the semiconductor element is mounted.
