SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

The invention is directed to providing a smaller semiconductor device formed as an optical sensor including a light receiving portion and a light emitting portion. A light receiving portion and a light emitting portion are disposed on a front surface of a semiconductor substrate for forming a semiconductor die, and a supporting body is attached to these so as to face these with an adhesive being interposed therebetween. A first opening exposing the light receiving portion from the front side of the supporting body is provided, and in a separated position therefrom, a second opening exposing the light emitting portion from the front side of the supporting body is provided. A first electrode and a second electrode are further disposed on the front surface of the semiconductor substrate, and bump electrodes electrically connected to these are disposed on the back surface of the semiconductor substrate.
