Patent number: 6943058Abstract: A no-flow underfill material and process suitable for underfilling a bumped circuit component. The underfill material initially comprises a dielectric polymer material in which is dispersed a precursor capable of reacting to form an inorganic filler. The underfill process generally entails dispensing the underfill material over terminals on a substrate, and then placing the component on the substrate so that the underfill material is penetrated by the bumps on the component and the bumps contact the terminals on the substrate. The bumps are then reflowed to form solid electrical interconnects that are encapsulated by the resulting underfill layer. The precursor may be reacted to form the inorganic filler either during or after reflow.Type: GrantFiled: March 18, 2003Date of Patent: September 13, 2005Assignee: Delphi Technologies, Inc.Inventors: Arun K. Chaudhuri, Derek B. Workman, Frank Stepniak, Matthew R. Walsh

Patent number: 6916684Abstract: A process for underfilling a bumped die surface using a lamination step and compound film such that solder bumps on the die are exposed during lamination. The compound film comprises a first layer containing an underfill material and a second layer on the first layer. The underfill material and the second layer comprise polymer materials that differ from each other. The compound film is laminated to the die, preferably at the wafer level, so that the underfill material is forced between the solder bumps and fills spaces between the bumps but does not cover the bumps. In contrast, the second layer covers the solder bumps, but is then selectively removed to re-expose the solder bumps and the underfill material therebetween.Type: GrantFiled: March 18, 2003Date of Patent: July 12, 2005Assignee: Delphi Technologies, Inc.Inventors: Frank Stepniak, Matthew R. Walsh, Arun K. Chaudhuri, Michael J. Varnau

Publication number: 20050046024Abstract: A metal runner that improves the current-carrying capability of solder bumps used to electrically connect a surface-mount circuit device to a substrate. The runner comprises at least one leg portion and a pad portion, with the pad portion having a continuous region and a plurality of separate electrical paths leading to and from the continuous region. The electrical paths are delineated in the pad portion by nonconductive regions defined in the pad portion, with at least some of the nonconductive regions extending into the leg portion. The multiple electrical paths split the current flow to and from the solder bump, distributing the current around the perimeter of the solder bump in a manner that reduces current density in regions of the solder bump where electromigration is most likely.Type: ApplicationFiled: October 8, 2004Publication date: March 3, 2005Inventors: Pankaj Mithal, William Higdon, Mark Gose, John Dikeman, Frank Stepniak
