A backside method for fabricating a semiconductor component (50) with a conductive interconnect (44) includes the step of providing a semiconductor substrate (12) having a circuit side (14), a backside (16), and a substrate contact (18) on the circuit side (14). The method also includes the steps of forming a substrate opening (30) from the backside (16) to the substrate contact (18), and then bonding the conductive interconnect (44) to an inner surface (32) of the substrate contact (18). A system (62) for performing the method includes the semiconductor substrate (12), a thinning system (64) for thinning the semiconductor substrate (12), an etching system (66A) for forming the substrate opening (30), and a bonding system (38) for bonding the conductive interconnect (44) to the substrate contact (18). The semiconductor component (50) can be used to form module components (98), underfilled components (106), stacked components (116), and image sensor semiconductor components (50IS).
Abstract:
An integrated circuit chip with its interconnecting pads re-arranged in substantially a straight line. The pads are ordered in the straight line so that wire bond connections to contact terminal of an IC package allows the wire bonds to not interfere with each other by traveling under or over other wire bonds. This re-arrangement and ordering of an IC's pads allows a single die constructed in accordance with this invention to be mounted in both a package that is designed to accept a die-down type chip and a package designed to accept a die-up type chip. This mounting of the single chip occurs directly without any other transition artifacts, like transition substrates, etc., that would carry the reversal of the effective pad locations.

An electronic component package and a method of forming the package are disclosed. The package includes a die having a top face with set of contacts and a substrate having a cutout therein. The die may include a memory component and may include SDRAM. The substrate is mounted on the top face, and the cutout overlays the set of contacts. Wire leads extend from the set of contacts, at least partially through the cutout, to the substrate. The set of contacts may be positioned along a central region of the die, and the cutout overlays the central region. The wire leads extend to the substrate and may contact the substrate proximate to the cutout. The package may further include a set of electrical paths extending from the wire leads through the substrate for providing communicative path between the die and an external component.
