Patent 7208383 was granted and assigned to Advanced Micro Devices on April, 2007 by the United States Patent and Trademark Office.
An insulated gate field effect transistor having reduced gate-drain overlap and a method for manufacturing the insulated gate field effect transistor. A gate structure is formed on a major surface of a semiconductor substrate. A source extension region and a drain extension region are formed in a semiconductor material using an angled implant. The source extension region extends under the gate structure, whereas the drain extension region is laterally spaced apart from the gate structure. A source region is formed in the semiconductor substrate and a drain region is formed in the semiconductor substrate, where the source and drain regions are laterally spaced apart from the gate structure. A source-side halo region is formed in the semiconductor substrate adjacent the source extension region.
