ALEXANDRIA, Va., Jan. 1 -- GLOBALFOUNDRIES, Grand Cayman, Cayman Islands, has been assigned a patent (8,338,274) developed by four co-inventors for a "transistor device comprising an embedded semiconductor alloy having an asymmetric configuration." The co-inventors are Stephan Kronholz, Dresden, Germany, Vassilios Papageorgiou, Austin, Texas, Gunda Beernink, Dresden, Germany, and Jan Hoentschel, Dresden, Germany.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "In sophisticated semiconductor devices, an asymmetric transistor configuration may be obtained on the basis of a strain-inducing semiconductor alloy. To this end, strain relaxation implantation processes may be performed at the drain side according to some illustrative embodiments, while, in other cases, the deposition of the strain-inducing alloy may be performed in an asymmetric manner with respect to the drain side and the source side of the transistor."
The patent application was filed on Dec. 29, 2009 (12/648,867). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,338,274.PN.&OS=PN/8,338,274&RS=PN/8,338,274
