Patent ID: 7078794

Claim:
A chip package structure, comprising: a substrate having a first surface and a corresponding second surface, wherein the substrate has a slot that penetrates the substrate, the substrate having a plurality of substrate bump pads on the first surface positioned around the slot, a plurality of substrate contact pads on the first surface positioned around the slot, and a plurality of substrate wire pads on the second surface positioned around the slot; a chip having an active surface, wherein the sectional area of the active surface is larger than the sectional area of the slot in the substrate, the chip is attached to the first surface of the substrate and covers the slot such that the active surface faces the slot, the chip futhermore has a plurality of chip bump pads and a plurality of chip wire pads, wherein the chip wire pads are formed in the central region of the active surface and the chip bump pads are formed in the peripheral region of the active surface; a plurality of bumps, wherein one end of each bump is attached to a chip bump pad and the other end of the bump is attached to a substrate bump pad; a plurality of conductive wires that passes through the slot in the substrate, wherein one end of each conductive wire is attached to a chip wire pad and the other end is attached to a substrate wire pad; an insulating material formed between the chip and the substrate and inside the slot so that the conductive wires and the bumps are enclosed; and a plurality of contacts attached to the substrate contact pads on the first surface respectively, and electrically connected to circuits within the substrate so that the substrate is electrically connected to external circuits through the contacts, wherein the contacts are conductive structures selected from the group consisted of solder balls, pins, or electrode bumps.
