Patent number: 7087513Abstract: The present invention provides a method for producing a temporary chip carrier for semiconductor chip burn-in test and speed sorting. A multi-layered substrate or card, usually comprised of one of various materials is made by offsetting the conductor-filled vias or holes in the outer few layers with the outer most layer not being filled with a conductor, such that a partially filled via or hole is produced. This effectively produces a smaller surface conductor feature, on which the semiconductor chip is temporarily attached, electrically tested, and subsequently removed using various methods, at forces much lower than normal chip removal processes require.Type: GrantFiled: October 26, 2004Date of Patent: August 8, 2006Assignee: International Business Machines CorporationInventors: Benjamin V.

Patent number: 6823585Abstract: A method and structure to form surface plating metallization on a substrate. Two layers of tape are applied to the surface of the substrate. A first path is cut through both layers of tape exposing the substrate surface. The first path connects at least one conductive via on the top surface of the substrate. A second path is cut through the second layer of tape exposing the first layer of tape. The second path is routed from the first path to an edge of the substrate A seed layer is deposited over the surface of the second layer of tape thereby creating a seeded plating path in the first path and a sacrificial seeded conduction path in the second path. Connecting the sacrificial seeded conduction path to a plating potential at the edge of the substrate creates a plated path on the surface of the substrate. The sacrificial path is removed when the tape is removed.Type: GrantFiled: March 28, 2003Date of Patent: November 30, 2004Assignee: International Business Machines CorporationInventors: Mark J.

Patent number: 6312791Abstract: Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to a middle pad of the multilayer ceramic substrate by a plurality of vias which in turn is anchored to an inner pad of the multilayer ceramic substrate by a second plurality of vias. The middle and outer pads and vias are made of high metal material, preferably 100% metal, so they won't adhere very well to the ceramic substrate. The inner pad is a composite metal/ceramic material which will bond very well to the ceramic substrate.Type: GrantFiled: August 25, 2000Date of Patent: November 6, 2001Assignee: International Business Machines CorporationInventors: Benjamin V.

Patent number: 6258191Abstract: Multilayer glass ceramic substrate electronic components having enhanced flexibility and strength are prepared using greensheets as a top and/or bottom layer, which greensheets are made from a glass-ceramic greensheet casting composition comprising crystallizable glass, a binder resin and a solvent system, and preferably a plasticizer. The top and/or bottom greensheets have a lower coefficient of thermal expansion (CTE) than the greensheets used to make the internal layers of the MLC and both greensheets are characterized by having, after sintering, a microstructure which is greater than 99% crystalline. A crystalline matrix forming material such as P2O5 is preferably used in the composition. This type structure, in combination with the lower CTE, has been found to provide an MLC having enhanced strength and flexibility.Type: GrantFiled: September 16, 1998Date of Patent: July 10, 2001Assignee: International Business Machines CorporationInventors: Benjamin V.

Patent number: 4663186Abstract: Disclosed is a screening paste for covering a selected portion of a metallurgical pattern on a substrate while leaving other metallurgy uncovered. The paste is free of polymers and consists, in one example, of 75-80% of a ceramic particulate (such as alumina), 2-8% amorphous fumed silica and 15-20% of linear alcohol. The linear alcohol serves as a vehicle to deliver the solid particles in the paste. In use, after covering the selected portion of the metallurgical pattern with the paste, the alcohol content therein is expelled by subjecting to vacuum treatment at room temperature or heating to a low temperature below about 275.degree. C. thereby obtaining an inert, dry and crack-free protective coating. Upon evaporation of a new metal layer onto the substrate and removal of the protective coating and new metal layer from everywhere except the uncovered metallurgy, the metallurgical pattern is selectively coated with the new metal.Type: GrantFiled: April 24, 1986Date of Patent: May 5, 1987Assignee: International Business Machines CorporationInventors: Richard F.
