Patent ID: 7629193

Claim:
A method of producing an acceleration sensor chip package, comprising the steps of: preparing a semiconductor substrate having a plurality of acceleration sensors arranged in a matrix pattern, each of said acceleration sensors having an electrode pad and a movable structure disposed in an opening portion; attaching a substrate to a lower surface of the semiconductor substrate; forming a re-wiring layer extending on the semiconductor substrate outside the opening portions and having a plurality of wiring portions, each of said wiring portions having one end electrically connected to each of the electrode pads; forming a plurality of outer terminals on the semiconductor substrate outside the opening portions, each of said outer terminals being connected to the other end of each of the wiring portions; forming a plurality of conductive bumps connected to the electrode pads; attaching a sensor control chip having a first surface and a second surface opposite to the first surface, said sensor control chip having, sensor control electrode pads connected to the electrode pads; forming a sealing portion over the acceleration sensors for sealing the sensor control chip, the electrode pads, and the re-wiring layer such that the outer terminals are exposed from the sealing portion; and cutting the sealing portion, the semiconductor substrate, and the substrate situated between the acceleration sensors to obtain the acceleration sensor chip package as a piece.
