Image sensitive electronic device packages
First Claim
1. An electronic device package comprising:
- a carrier substrate having at least one conductive trace thereon, the at least one conductive trace having a first end and a second end;
an electronic device sensitive to light or other radiation attached to a surface of the carrier substrate;
at least one electrical interconnection between a bond pad on the electronic device and the first end of the at least one conductive trace; and
a shell formed entirely of a transparent material attached to the surface of the carrier substrate, the shell enclosing the first end of the at least one conductive trace, the at least one electrical interconnection and the electronic device.

Abstract
The invention provides methods for packaging for electronic devices that are light or other radiation-sensitive, such as image sensors including CCD or CMOS chips. In one embodiment of the invention, an image sensor package is assembled by surrounding a chip with a barrier of transfer mold compound and covering the chip with a transparent lid. In another embodiment of the invention, the perimeter area of a chip, including interconnections such as wire bonds and bond pads, is encapsulated with a liquid dispensed epoxy, and a transparent lid is attached. In yet another embodiment of the invention, chip encapsulation is accomplished with a unitary shell of entirely transparent material. In yet another embodiment of the invention, a substrate-mounted chip and a transparent lid are loaded into a transfer mold that holds them in optimal alignment.
