Abstract
An SOI/SOS thin film MOS mesa architecture has its body/channel region extended beyond the source and drain regions and the impurity concentration is increased at an end portion of the extended body region, so as to provide a channel stop region that is effective to functionally interrupt a current leakage path or `parasitic` N-channel that may be induced along sidewall surface of the P-type material of the body/channel region. In addition, in order to inhibit radiation-induced leakage along a backside interface of the extended body region abutting an underlying dielectric substrate, a portion of the extended body region between the channel stop region and the body/channel region has an impurity concentration profile that is increased at the interface of the extended body region with the underlying dielectric substrate.
