Abstract: A package for a flip chip integrated circuit including an interposer with electrical interconnecting for signal, power, and ground contacts. Routing is accomplished on only two conductor layers through the use of selective planes and buses. Multiple power planes are provided on a single conductor level to support circuits having different operating voltages. A unique cavity down BGA package for a flip chip interconnected integrated circuit is provided by adhering the interposer to a thermally conductive stiffener or base, and using solder balls to attach the frame to the base and interposer. The assemblage forms a chip cavity with interconnecting vias to external BGA solder balls terminals located in the perimeter frame.

Abstract: A package 300 for a flip chip integrated 331 circuit including an interposer 303 with electrical interconnecting for signal, power, and ground contacts. Routing is accomplished on only two conductor layers through the use of selective planes and buses. Multiple power planes are provided on a single conductor level to support circuits having different operating voltages. A unique cavity down BGA package for a flip chip interconnected integrated circuit is provided by adhering the interposer to a thermally conductive stiffener or base 304, and using solder balls 308 to attach the frame to the base and interposer. The assemblage forms a chip cavity with interconnecting vias to external BGA solder balls terminals located in the perimeter frame.

Abstract: In accordance with the invention, integrated circuit dies may be packaged in a plastic package employing an area area array technology such as a conductive ball grid array, column grid array or pin grid array. One aspect of the invention is an integrated circuit package (10) which includes an electronic circuit enclosed by a plastic body (12, 14). The molded plastic body has a first major surface opposing a second major surface. The first major surface of integrated circuit (10) has a plurality of openings therein. One of a plurality of conductive pads (18) is adjacent to each one of the openings and is electrically connected to the electronic circuit. Each of a plurality of conductors (20) is electrically connected to one of the pads (18) and protrudes from one of the openings (22).
