Abstract:
1. A method for producing a semiconductor device, comprising: etching one surface of a semiconductor plate to form a recess in the one surface, the recess having a depth that is less than a thickness of the semiconductor plate so that the recess does not extend through the semiconductor plate; extending wirings along a surface of the recess and along the one surface of said semiconductor plate; placing, in the recess, at least one semiconductor pellet having at least one semiconductor device element disposed therein and having bonding pads arranged thereon; connecting said bonding pads with said wirings using bonding wires; burying the recess with a resin; disposing a plurality of electrodes along the one surface of said semiconductor plate so as to be connected with said wirings; and etching an upper surface of the semiconductor plate to have an uneven configuration, wherein the one surface of the semiconductor plate is lower surface of the semiconductor plate.
