Patent number: 8158453Abstract: A CMOS active pixel sensor (APS) cell structure having dual workfunction transfer gate device and method of fabrication. The transfer gate device comprises a dielectric layer formed on a substrate and a dual workfunction gate conductor layer formed on the dielectric layer comprising a first conductivity type doped region and an abutting second conductivity type doped region. The transfer gate device defines a channel region where charge accumulated by a photosensing device is transferred to a diffusion region. A silicide structure is formed atop the dual workfunction gate conductor layer for electrically coupling the first and second conductivity type doped regions. In one embodiment, the silicide contact is smaller in area dimension than an area dimension of said dual workfunction gate conductor layer. Presence of the silicide strap prevents the diodic behavior from allowing one or the other side of the gate to float to an indeterminate voltage.Type: GrantFiled: February 3, 2010Date of Patent: April 17, 2012Assignees: International Business Machines Corporation, Omnivision Technologies, Inc.Inventors: James W.

Patent number: 7973836Abstract: A method for lowering dark current in an image sensor pixel, the method includes the steps of providing a photosensitive area for receiving incident light which is converted into a charge; providing a gate for transferring charge from the photosensitive area; wherein the gate is held at a voltage which will accumulate majority carriers at a semiconductor-dielectric interface during integration for the photosensitive area. Alternatively, a potential profile can be provided under the gate to drain the dark current away from the photogeneration diffusion.Type: GrantFiled: October 28, 2004Date of Patent: July 5, 2011Assignee: OmniVision Technologies, Inc.Inventors: R.

Publication number: 20100157852Abstract: Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. A computer or other processor includes a local area network controller, which provides routing and hub(s) for one or more packet networks. The computer also is coupled to a buffer/framer, which serves to frame/deframe data to/from the computer from TDM bus.Type: ApplicationFiled: September 8, 2009Publication date: June 24, 2010Inventors: Edward T Nelson, Scott K.
