An electronic subsystem employing stacked modules is described, with optical ports at each of the modules.Type: ApplicationFiled: July 27, 2006Publication date: February 1, 2007Inventor: Peter Salmon

Publication number: 20070023905Abstract: Some embodiments of the present invention relate to a semiconducting device that includes an interposer having a fold which divides the interposer into a first section and a second section. A first die is attached to a first surface of the interposer at the first and second sections of the interposer. The semiconducting device further includes a contact that is attached to the first surface of the interposer at the first section and the second section. A second die is attached to a second surface of the interposer such that the second die is stacked onto the first die and is electrically coupled to the first die by the contact and conductive paths that are part of the interposer.Type: ApplicationFiled: September 22, 2006Publication date: February 1, 2007Inventors: Iwen Chao, Steve Eskildsen

Publication number: 20070023906Abstract: A semiconductor device-composing substrate 10 has a support base 12, an interconnect layer 14 including interconnects 13, and an insulating resin layer 16. The semiconductor device-composing substrate 10 also has a mounting region D1 on which a semiconductor chip 30 is to be mounted. The insulating resin layer 16 is formed on the interconnect layer 14. Chip-connecting electrodes 17, external electrode pads 18 and the resin stopper patterns 19 are formed in the insulating resin layer 16. The chip-connecting electrodes 17 are provided in the mounting region D1. The external electrode pads 18 are provided outside the mounting region D1. The resin stopper patterns 19 are provided between the mounting region D1 and the external electrode pads 18.Type: ApplicationFiled: October 5, 2006Publication date: February 1, 2007Applicant: NEC ELECTRONICS CORPORATIONInventors: Yoichiro Kurita, Koji Soejima, Masaya Kawano

Publication number: 20070023907Abstract: A method of forming a self-assembled interconnect structure is described. In the method, a contact pad surface and particles in a solution are brought together. The particles are selected such that they the particles adhere to the contact pad surface. Formation of a contact is completed by pressing an opposite contact into the particles such that an electrical connection is formed via the particles between the opposite contact pad and the substrate surface contact pad. The described self-assembled interconnect structure is particularly useful in display device fabrication.Type: ApplicationFiled: July 27, 2005Publication date: February 1, 2007Inventors: David Fork, Thomas Hantschel, Michael Chabinyc
