Patent number: 6475838Abstract: A decoupling capacitor and methods for forming the same are provided. In a first aspect, the decoupling capacitor is formed during a process for forming first and second type FETs on a common substrate that comprises a plurality of implant steps for doping channels and diffusions of the first and second type FETs. In a second aspect, a method is provided for forming the novel decoupling capacitor that includes the steps of forming a mandrel layer on a substrate, including forming openings in the mandrel layer and disposing a first type dopant into the substrate through the openings. Thereafter, an epitaxial layer is formed in the openings on the substrate, an insulator layer is formed in the openings on the epitaxial layer and a gate is formed in the openings on the insulator layer. The mandrel layer is removed and the first type dopant is disposed into the substrate abutting the first type dopant in the substrate that was disposed through the openings.Type: GrantFiled: March 14, 2000Date of Patent: November 5, 2002Assignee: International Business Machines CorporationInventors: Andres Bryant, William F.

Patent number: 6249029Abstract: A device design for an FET in SOI CMOS which is designed for enhanced avalanche multiplication of current through the device when the FET is on, and to remove the body charge when the FET is off. The FET has an electrically floating body and is substantially electrically isolated from the substrate. The present invention provides a high resistance path coupling the floating body of the FET to the source of the FET, such that the resistor enables the device to act as a floating body for active switching purposes and as a grounded body in a standby mode to reduce leakage current. The high resistance path has a resistance of at least 1 M-ohm, and comprises a polysilicon resistor which is fabricated by using a split polysilicon process in which a buried contact mask opens a hole in a first polysilicon layer to allow a second polysilicon layer to contact the substrate.Type: GrantFiled: May 26, 1999Date of Patent: June 19, 2001Assignee: International Business Machines CorporationInventors: Andres Bryant, William F.

Patent number: 5837256Abstract: It has been found that by administering secoisolariciresinol ?2,3-bis(3-methyl-4-hydroxybenzyl)butane-1,4-diol! from flaxseed in substantially pure form to a human or non-human animal, lupus nephritis can be controlled. The secoisolariciresinol (Seco) may be used per se or in the form of secoisolariciresinol diglucoside (SDG). Both compounds may be extracted from flaxseed and the SDG converts to Seco in the gut of a human or animal.Type: GrantFiled: December 19, 1996Date of Patent: November 17, 1998Inventors: William F.

Patent number: 5159373Abstract: In use with a photosensitive web roll located inside a light-tight container having an exit slot through which the web is withdrawable, a flexible enclosure is provided for light-shielding a leading end portion of the web extending from the roll through the slot and outside the container. The enclosure comprises a flexible, substantially rectangular, opaque sleeve adapted to enclose the web end portion. The sleeve includes opposing top and bottom walls disposed in adjacent, registered, facing relationship and extending between front and rear ends and opposite lateral sides thereof. The walls are light-tightly joined together along their front ends and lateral sides, but are left unjoined and separable along their rear ends to provide an opening therebetween through which the web end portion can be inserted into the sleeve toward the joined front ends.Type: GrantFiled: July 31, 1991Date of Patent: October 27, 1992Assignee: Eastman Kodak CompanyInventors: William F.
