Abstract
An object of the invention is to provide a smaller semiconductor device of which the manufacturing process is simplified and the manufacturing cost is reduced. Furthermore, an object of the invention is to provide a semiconductor device having a cavity. A device elementis formed on a front surface of a semiconductor substrateand a sealing bodyis attached to the semiconductor substratewith an adhesive layerbeing interposed therebetween. A main surface (a back surface) of the sealing bodywhich faces the semiconductor substrateis curved inward, and there is a given space (a cavity) between the sealing bodyand the semiconductor substrateSince the back surface of the sealing bodyis curved, the sealing bodyis used as a planoconcave lens (a reverse direction) as well as a sealing member for the device element
