Abstract
A semiconductor substrate of a solid state imaging device is connected to a cover glass, and then a backgrind is performed so as to make the thickness smaller. On a first face of the semiconductor substrate is formed plural units which is constructed of image sensors and plural contact terminals. At positions of the contact terminals, plural through-holes are formed on the bottom side of the semiconductor substrate, and the contact terminals appear on a second surface of the semiconductor substrate. On an interconnection circuit pattern of the assembly substrate are formed stud bumps. When the semiconductor substrate is assembled onto the assembly substrate, the stud bumps enter into the through-holes to contact to the contact terminals. Thus the interconnection circuit pattern is electrically connected to the image sensors.
