Abstract
A method for forming a transistor is formed where a gate electrode of the transistor is formed over a substrate defining a gate channel portion of the substrate. A mask is also formed over the substrate, a portion of the mask extending over a first portion of the substrate adjacent to the gate channel portion of the substrate. The mask defines a second portion of the substrate adjacent to the first portion of the substrate. An ion beam is directed toward the substrate to form a drain or a source region of said transistor adjacent to the gate channel portion of the substrate, the source or drain region including the first and second portions of the substrate. The ion beam implants the second portion of the substrate with a first implantation characteristic. The ion beam passes through the extended portion of the mask to reach the first portion to implant the first portion with a second implantation characteristic, such second implantation characteristic being different from the first implantation characteristic.
