Patent number: 7847389Abstract: Even when a substrate on which a semiconductor package has been mounted is made curved, stress upon electrical connections is mitigated, thereby eliminating faulty connections and improving connection reliability. A semiconductor chip has electrodes on a second face thereof. Support blocks, capable of bending and flexing, are placed at two locations on a peripheral edge of a first face of the semiconductor chip. An interposer is placed so as to span the support blocks with the support blocks interposed between itself and the semiconductor chip, and has a wiring pattern in a flexible resin film. Two end portions of the interposer are folded back onto the side of the second face of the semiconductor chip, and the wiring pattern thereof is electrically connected to the electrodes of the semiconductor chip.Type: GrantFiled: November 13, 2006Date of Patent: December 7, 2010Assignee: NEC CorporationInventors: Nobuhiro Mikami, Shinji Watanabe, Junya Sato, Atsumasa Sawada

Publication number: 20100252922Abstract: The invention relates to a power semiconductor module including a power semiconductor chip arranged on a substrate and comprising a bottom side facing the substrate, a top side facing away from the substrate, and an electrical contact face arranged on the top side. A bond wire is bonded to the contact face. At least when the power semiconductor module is fastened to a heatsink, a contact pressure element creates a contact pressure force (F) acting on a sub-portion 36 of a bond wire portion configured between two adjacent bond sites. The contact pressure force (F) results in the power semiconductor chip and a substrate beneath being pressed against the heatsink.Type: ApplicationFiled: April 1, 2010Publication date: October 7, 2010Applicant: INFINEON TECHNOLOGIES AGInventors: Reinhold Bayerer, Olaf Hohlfeld, Thilo Stolze

Patent number: 7752738Abstract: Systems and methods are provided for fabricating compliant spring contacts for use in, for example, IC packaging and interconnection between multi-layers in stacked IC packages and electronic components. Internal stresses generated within an formed film are released to cause the film to buckle and/or bow away from a supporting terminal. A thin stressed metal film layer is selectively broken away from the substrate of the supporting terminal allowing the stressed metal film to take on a bowed and/or spring-like shaped through minute deformation based on a release of the internal stresses. The resultant thin compliant spring contact can deform a small amount as the spring contact is then pressed against a compatible mating contact surface in an overlying layer.Type: GrantFiled: January 24, 2005Date of Patent: July 13, 2010Assignee: Palo Alto Research Center IncorporatedInventor: Thomas H. DiStefano
