Patent ID: 8110933

Claim:
A semiconductor device mounted structure comprising: a semiconductor device having a plurality of device electrodes; a board having a plurality of board electrodes; a plurality of bump electrodes for connecting the device electrodes and the board electrodes to each other, respectively; a sealing-bonding resin which seals the device electrodes, the board electrodes and the bump electrodes, respectively, and which is placed between the semiconductor device and the board so as to make the semiconductor device and the board bonded to each and other; a recess portion which is formed in an electrode formation surface of the board at a position facing a peripheral end portion of the semiconductor device, and in which the sealing-bonding resin is placed partially inside thereof; and a stop layer for machining which is exposed in an inner bottom portion of the recess portion; wherein the recess portion has the inner bottom portion which is inclined so as to increasingly deepen toward a periphery of the semiconductor-device opposing region of the board.
