Abstract
A direct-contact type image sensor device according to the present invention includes: a light-transmitting substrate having an upper surface and a lower surface; a patterned conductor layer formed over the upper surface of the light-transmitting substrate; a transparent electrically conductive layer formed on the lower surface of the light-transmitting substrate; an image sensor chip mounted face-down on the upper surface of the light-transmitting substrate, with an insulating resin layer being interposed between the image sensor chip and the upper surface of the light-transmitting substrate, the image sensor chip being mounted by a flip-chip-bonding method, a light-interrupting layer provided between the patterned conductor layer and the upper surface of the light-transmitting substrate; and a light-interrupting portion for interrupting a portion of a light beam, the light beam being radiated on an original through the light-transmitting substrate by a light source disposed above the light-transmitting substrate. The image sensor chip and the light-interrupting portion serve as an optical throttle for the light beam.
