Method For Reducing Coefficient Of Thermal Expansion In Chip Attach Packages

US Patent:
6586352, Jul 1, 2003
Filed:
Oct 20, 2000
Appl. No.:
09/693766
Inventors:
Lawrence Robert Blumberg - Johnson City NY
Robert Maynard Japp - Vestal NY
William John Rudik - Vestal NY
John Frank Surowka - Binghamton NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B32B 2709
US Classification:
442181, 442103, 442247, 442255, 29832
Abstract:
A simple, inexpensive, drillable, reduced CTE laminate and circuitized structure comprising the reduced CTE laminate, is provided. The reduced CTE laminate comprises: from about 40% to 75%, preferably from about 55% to 65%, by weight resin; from about 0. 05% to 0. 3%, preferably from about 0. 08% to 0. 10%, by weight curing agent; from about 25% to 60%, preferably from about 30% to 40%, by weight, woven cloth; from about 1% to 15%, preferably from about 5% to 10%, by volume, non-woven quartz mat. The present invention also generally relates to a method for reducing the CTE of circuitized structures, and to methods for making reduced CTE laminate and circuitized structures comprising reduced CTE laminate. The method for making reduced CTE laminate and laminate structures comprises the following steps: providing non-woven quartz mat; providing a prepreg, preferably B-stage cured to not more than about 40%, preferably not more than 30% of full cure; sandwiching the non-woven quartz mat between two layers of prepreg, and reflowing the resin of the prepreg into the quartz mat. The method further comprises providing a resin volume percent, woven glass cloth volume percent and metal volume percent of the circuitized structure to be fabricated; selecting a desired CTE for the circuitized structure to be fabricated; and determining the amount of non-woven quartz or non-woven glass mat to be incorporated according to a formula.

Electrical Coupling Of A Stiffener To A Chip Carrier

US Patent:
6534848, Mar 18, 2003
Filed:
Sep 7, 2000
Appl. No.:
09/657194
Inventors:
Terry J. Dornbos - Vestal NY
Mark V. Pierson - Binghamton NY
William J. Rudik - Vestal NY
David L. Thomas - Endicott NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01L 2302
US Classification:
257678, 257706
Abstract:
A method and structure for conductively coupling a metallic stiffener to a chip carrier. A substrate has a conductive pad on its surface and an adhesive layer is formed on the substrate surface. The metallic stiffener is placed on the adhesive layer, wherein the adhesive layer mechanically couples the stiffener to the substrate surface and electrically couples the stiffener to the pad. The adhesive layer is then cured such as by pressurization at elevated temperature. Embodiments of the present invention form the adhesive layer by forming an electrically conductive contact on the pad and setting a dry adhesive on the substrate, such that the electrically conductive contact is within a hole in the dry adhesive. The electrically conductive contact electrically couples the stiffener to the pad. The curing step includes curing both the dry adhesive and the electrically conductive contact, resulting in the dry adhesive adhesively coupling the stiffener to the substrate.

Technique For Forming Resin-Impregnated Fiberglass Sheets Using Multiple Resins

US Patent:
5866203, Feb 2, 1999
Filed:
Jul 9, 1997
Appl. No.:
8/890527
Inventors:
Bernd Karl Appelt - Apalachin NY
Robert Maynard Japp - Vestal NY
Kostantinos Papathomas - Endicott NY
William John Rudik - Vestal NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B32B 3108, B32B 700
US Classification:
427217
Abstract:
A method and resultant article are provided which optimize the adhesion of resin to the glass fibers in fiberglass cloth impregnated with a resin and also optimize the adhesion of the impregnated resin to metal sheets laminated to the resin-impregnated cloth. The fiberglass is treated in two or more passes. On the first pass, the fiberglass is impregnated with a first resin which is optimized for adherence to glass fibers and the coated resin is partially cured. In a last pass, the fiberglass is impregnated with a second resin, which is different from said first resin, and is optimized for bonding to metal. The second resin is then partially cured. The first and second resins are selected such that they form a bond with each other when cured.

Technique For Forming Resin-Impregnated Fiberglass Sheets With Improved Resistance To Pinholing

US Patent:
6096665, Aug 1, 2000
Filed:
Jul 9, 1997
Appl. No.:
8/891423
Inventors:
Bernd Karl Appelt - Apalachin NY
Robert Maynard Japp - Vestal NY
Kostantinos Papathomas - Endicott NY
William John Rudik - Vestal NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B05D 138, B32B 3108
US Classification:
442 62
Abstract:
A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture as well as most of the interstices or openings, although some of the interstices or openings have holes where the coating does not completely fill in. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in any holes in the first coating. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. This substantially reduces pinholing.

International Classification:
H01L 2144, H01L 2148, H01L 2150
US Classification:
438108
Abstract:
A method for forming a flip-chip-on-board assembly. An integrated circuit (IC) chip having a polyimide passivation layer is joined to a chip carrier via a plurality of solder bumps which electrically connect a plurality of contact pads on the IC chip to corresponding contacts on the chip carrier. A space is formed between a surface of the passivation layer and a surface of the chip carrier. A plasma is applied, to chemically modify the surface of the chip carrier and the passivation layer of the IC chip substantially without roughening the surface of the passivation layer. The plasma is either an O. sub. 2 plasma or a microwave-generated Ar and N. sub. 2 O plasma. An underfill encapsulant material is applied to fill the space. The plasma treatment may be performed after the step of joining. Then, the chip and chip carrier are treated with the plasma simultaneously.
