Thin integrated circuit package having an optically transparent window
First Claim
1. An optical integrated circuit, comprising:
- a flexible plastic tape having a conductive pattern disposed on a top surface thereof;
a die mounted to the top surface of the tape and electrically coupled to the conductive pattern for providing an electronic function of the integrated circuit;
a support structure surrounding the die and bonded to the top surface of the tape;
a transparent cover mounted over the die such that an optically active surface of the die is accessible through the transparent cover; and
a plurality of external contacts disposed on a bottom surface of the tape opposite the top surface and electrically coupled to the conductive pattern through holes formed in the tape from the bottom surface to the top surface, for providing an electrical interface to the die.

Abstract
A thin integrated circuit package having an optically transparent window provides a small profile optical integrated circuit assembly for use in digital cameras, video cellular telephones and other devices requiring a small physical size and optical integrated circuit technology. A tape having a conductive metal layer on a surface is used to interface the optical integrated circuit die with electrical interconnects disposed on a surface of the tape opposite the die. A supporting structure surrounds the die and a glass cover is either bonded to the top of the supporting structure over the die, or the glass cover is bonded to the top of the die and the gap between the glass cover and supporting structure filled with encapsulant. The resulting assembly yields a very thin optical integrated circuit package.
