A sealing resin seals the upper portion of the main surface of the semiconductor wafer, and external connection terminals are formed at the upper portion of the main surface so as to project out from the surface of the sealing resin and are arrayed in a substantially regular pattern over specific intervals from one another. At least one of the external connection terminals has a shape different from the shape of the other external connection terminals. The shape of the external connection terminal is used as an index mark, so that the index mark forming process is simplified and the index mark does not come off.Type: GrantFiled: April 25, 2002Date of Patent: September 7, 2004Assignee: Oki Electric Industry Co., Ltd.Inventors: Yuuki Furuya, Akihisa Iguchi, Kentarou Arai

Publication number: 20040075165Abstract: The present invention relates to apparatus and methods for providing a low resistance power supply to a microelectronic package through the use of dual conductive paths. A first conductive path contained within the substrate and supplies current, primarily in responding to transient current demands to the microelectronic package. A lower resistance second conductive path supplies primarily steady state current to the microelectronic package through an electrical connection to an edge of the microelectronic package. Resistance in the second conductive path is reduced by using a power clamp to connect the second power supply to the microelectronic package.Type: ApplicationFiled: October 18, 2002Publication date: April 22, 2004Inventors: Kris Frutschy, Glenn Stewart, Hong Xie, Brent Stone
