Publication number: 20070029581Abstract: The present invention is a pixel sensor cell and method of making the same. The pixel sensor cell approximately doubles the available signal for a given quanta of light. The device of the present invention utilizes the holes produced by impinging photons in a pixel sensor cell circuit. A pixel sensor cell having reduced complexity includes an n-type collection well region formed beneath a surface of a substrate for collecting electrons generated by electromagnetic radiation impinging on the pixel sensor cell and a p-type collection well region formed beneath the surface of the substrate for collecting holes generated by the impinging photons. A circuit structure having a first input is coupled to the n-type collection well region and a second input is coupled to the p-type collection well region, wherein an output signal of the pixel sensor cell is the magnitude of the difference of a signal of the first input and a signal of the second input.Type: ApplicationFiled: August 8, 2005Publication date: February 8, 2007Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: James Adkisson, Andres Bryant, John Ellis-Monaghan, Mark Jaffe, Jeffrey Johnson, Alain Loiseau

Publication number: 20070029584Abstract: An electronic circuit is formed by closely spacing metallic gate and drain interconnects to a flexible portion of a source interconnect. A gate voltage results in electrostatic attraction and lateral mechanical movement of the flexible source interconnect portion and causes an electrical short between source and drain. VanderWaals attraction between contacting source and drain can be used to provide volatile switching (springy thicker source portion) and non-volatile switching (limp thinner source portion). In accordance with the invention, an easily fabricated, high speed, low power, radiation hard, temperature independent, integrated reconfigurable electronic circuit with embedded logic and non-volatile memory can be realized. The switch uses patterned interconnect material for its structure and can be incorporated to a 3D layered structure consisting of three dimensional interconnect in which different layers and portions of the circuits are linked through volatile and non-volatile switches.Type: ApplicationFiled: August 2, 2005Publication date: February 8, 2007Inventors: Sergio Valenzuela, Douwe Monsma
