Patent ID: 8390087

Claim:
An image sensor package structure with a large air cavity, the image sensor package structure comprising: a substrate having: a first surface formed with a plurality of first conductive contacts; and a second surface; a chip having: a third surface bound with the first surface; a fourth surface including a sensitization area; and a plurality of second conductive contacts surrounding the sensitization area and electrically connected with the first conductive contacts; a cover having: a plastic sheet adhered to the fourth surface; and a transparent lid combined with the plastic sheet to provide a covering over the sensitization area and to define the air cavity over the sensitization area; and a package material deposited on the substrate to encapsulate peripheries of the chip and the cover; wherein the plastic sheet has a first board adhered to the fourth surface, a second board extending vertically from peripheral edges of the first board, and a third board extending transversely toward a center of the plastic sheet from a top of the second board so that a recess is defined by the first board, the second board, and the third board, and a periphery of the transparent lid is received in the recess.
