Abstract
In a semiconductor device in which a glass substrate is attached to a surface of a semiconductor die with an adhesive layer being interposed therebetween, it is an object to fill a recess portion of an insulation film formed on a photodiode with the adhesive layer without bubbles therein. In a semiconductor die in which an optical semiconductor integrated circuit including a photodiode having a recess portion of an interlayer insulation film in the upper portion, an NPN bipolar transistor, and so on are formed, generally, a light shield film covers a portion except the recess portion region on the photodiode and except a dicing region. In the invention, an opening slit is further formed in the light shield film, extending from the recess portion to the outside of the recess portion, so as to attain the object.
