Patent number: 7355221Abstract: A field effect transistor is provided which includes a contiguous single-crystal semiconductor region in which a source region, a channel region and a drain region are disposed. The channel region has an edge in common with the source region as a source edge, and the channel region further has an edge in common with the drain region as a drain edge. A gate conductor overlies the channel region. The field effect transistor further includes a structure which applies a stress at a first magnitude to only one of the source edge and the drain edge while applying the stress at no greater than a second magnitude to another one of the source edge and the drain edge, wherein the second magnitude has a value ranging from zero to about half the first magnitude. In a particular embodiment, the stress is applied at the first magnitude to the source edge while the zero or lower magnitude stress is applied to the drain edge.Type: GrantFiled: May 12, 2005Date of Patent: April 8, 2008Assignee: International Business Machines CorporationInventors: Gregory G.

Publication number: 20060071304Abstract: A structure, apparatus and method for a FET prime cell surrounded by a conductor is provided. The surrounding conductor includes a substrate contact arranged proximate a source of the FET. The surrounding conductor may be a ring substrate contact arranged within the substrate of the FET in electrical communication with elongated sources of the FET. No external contacts are needed to the ring substrate contact because no current flows therethrough while the ring substrate contact may act as a collection source for noise such as stray currents.Type: ApplicationFiled: September 29, 2004Publication date: April 6, 2006Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Basanth Jagannathan, John Pekarik, Christopher Schnabel

Publication number: 20050272195Abstract: A method and structure for an integrated circuit structure that utilizes complementary fin-type field effect transistors (FinFETs) is disclosed. The invention has a first-type of FinFET which includes a first fin, and a second-type of FinFET which includes a second fin running parallel to the first fin. The invention also has an insulator fin positioned between the source/drain regions of the first first-type of FinFET and the second-type of FinFET. The insulator fin has approximately the same width dimensions as the first fin and the second fin, such that the spacing between the first-type of FinFET and the second-type of FinFET is approximately equal to the width of one fin. The invention also has a common gate formed over channel regions of the first-type of FinFET and the second-type of FinFET. The gate includes a first impurity doping region adjacent the first-type of FinFET and a second impurity doping region adjacent the second-type of FinFET.Type: ApplicationFiled: July 21, 2005Publication date: December 8, 2005Inventors: Andres Bryant, William Clark, David Fried, Mark Jaffe, Edward Nowak, John Pekarik, Christopher Putnam
