Direct-contact type image sensor device, an image sensor unit, and methods for producing the same

A direct-contact type image sensor device comprising:

• a light-transmitting substrate having an upper surface and a lower surface;
• a patterned conductor layer formed on the upper surface of the light-transmitting substrate;
• a transparent electrically conductive layer formed on the lower surface of the light-transmitting substrate;
• and
• an image sensor chap 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,
• wherein the patterned conductor layer includes a circuit portion electrically connected to the image sensor chip 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 serving as an optical throttle for the light beam.
