  • Publication number: 20070222065
    Abstract: An electronic dive and method of fabricating an electronic device. The method including placing a placement guide over a top surface of a module substrate, the placement guide having a guide opening, the guide opening extending from a top surface of the placement guide to a bottom surface of the placement guide; aligning the placement guide to an integrated circuit chip position on the module substrate; fixing the placement guide to the module substrate; placing an integrated circuit chip in the guide opening, sidewalls of the placement guide opening constraining electrically conductive bonding structures on bottom surface of the integrated circuit chip to self-align to an electrically conductive module substrate contact pad on the top surface of the module substrate in the integrated circuit chip position; and bonding the bonding structures to the module substrate contact pads, the bonding structures and the module substrate contact pads in direct physical and electrical contact after the bonding.

  • Publication number: 20070048896
    Abstract: Conductive through vias are formed in electronic devices and electronic device carrier, such as, a silicon chip carrier. An annulus cavity is etched into the silicon carrier from the top side of the carrier and the cavity is filled with insulating material to form an isolation collar around a silicon core region. An insulating layer with at least one wiring level, having a portion in contact with the silicon core region, is formed on the top side of the carrier. Silicon is removed from the back side of the carrier sufficient to expose the distal portion of the isolation collar. The core region is etched out to expose the portion of the wiring level in contact with the silicon core region to form an empty via. The via is filled with conductive material in contact with the exposed portion of the wiring level to form a conductive through via to the wiring level. A solder bump formed, for example, from low melt C4 solder, is formed on the conductive via exposed on the carrier back side.

  • Publication number: 20060027934
    Abstract: A carrier structure and method for fabricating a carrier structure with through-vias each having a conductive structure with an effective coefficient of thermal expansion which is less than or closely matched to that of the substrate, and having an effective elastic modulus value which is less than or closely matches that of the substrate. The conductive structure may include concentric via fill areas having differing materials disposed concentrically therein, a core of the substrate material surrounded by an annular ring of conductive material, a core of CTE-matched non-conductive material surrounded by an annular ring of conductive material, a conductive via having an inner void with low CTE, or a full fill of a conductive composite material such as a metal-ceramic paste which has been sintered or fused.

  • Publication number: 20050037608
    Abstract: Flared and non-flared metallized deep vias having aspect ratios of about 2 or greater are provided. Blind vias have been fabricated in silicon substrates up to a depth of about 300 microns, and flared through vias have been fabricated up to about 750 microns, the approximate thickness of a silicon substrate wafer, enabling the formation of electrical connections at either or both ends of a via. In spite of the depth and high aspect ratios attainable, the etched vias are completely filled with plated copper conductor, completing the formation of deep vias and allowing fuller use of both sides of the substrate.
