Abstract:
A semiconductor device, comprising:a substrate including at least a first region having a first dopant concentration of a first conductivity type, wherein said first region is formed from the outdiffusion of second and third regions each having a second dopant concentration of the first conductivity type, the second dopant concentration being greater than the first dopant concentration; source and drain regions positioned within said second and third regions respectively, said source and drain regions each having a third dopant concentration of a second conductivity type, wherein said source and drain regions are separated by a channel region formed as part of said first region and having the first dopant concentration of the first conductivity type; and a gate positioned over said channel region, wherein said gate has a length (Lg) meeting the following relationship: Lg&lE;2*&agr;*Xj, where, &agr; is an outdiffusion factor, and Xj is a junction depth of each of said second and third regions.
