Abstract:
1. An acceleration sensor chip package, comprising: an acceleration sensor chip including a frame portion having an upper surface, a lower surface opposite to the upper surface, an inner region, an outer region surrounding the inner region, an opening portion formed in the inner region and extending from the upper surface to the lower surface, a movable structure having a beam portion extending from the frame portion toward inside the opening portion and a movable portion disposed in the opening portion and supported on the beam portion to be movable, a detection element for detecting a movement of the movable structure, and an electrode pad electrically connected to the detection element and disposed in the outer region; a re-wiring layer disposed on the outer region and including a wiring portion with two ends, one of said two ends being electrically connected to the electrode pad; an outer terminal electrically connected to the other of the two ends of the wiring portion; a conductive bump electrically connected to the electrode pad; a sensor control chip having a first surface, a second surface opposite to the first surface, and a sensor control electrode pad exposed from the first surface and electrically connected to the conductive bump; a sealing portion disposed over the acceleration sensor chip for sealing the sensor control chip, the electrode pad, and the re-wiring layer so that the outer terminal is exposed from the sealing portion and the movable structure is capable of operating; and a substrate attached to the lower surface for sealing the opening portion from below.
