Abstract:
A product produced by a method of manufacturing a semiconductor device, which method comprises:isolating a substantially rectilinear active area on a main surface of a semiconductor substrate, the active area comprising a first source/drain region and a second source/drain region, each having a source/drain width and a source/drain length, separated by a channel region having opposing ends not abutting either of the source/drain regions along the source/drain length; providing a field implant blocking mask over the channel region, the field implant blocking mask having a pair of substantially rectangular notches, each notch protruding over the channel region a predetermined distance along the source/drain width from one of the opposing ends of the channel region; and implanting impurities to form a field implant in the substrate and in portions of the channel region corresponding to the pair of notches.
