Abstract:
A semiconductor structure, such as a FinFET, etc., includes a bi-portioned junction. The bi-portioned junction includes a doped outer portion and a doped inner portion. The dopant concentration of the outer portion is less than the dopant concentration of the inner portion. An electrical connection is formed by diffusion of the dopants within outer portion into a channel region and diffusion of the dopants within the outer portion into the inner region. A low contact resistance is achieved by a contact electrically contacting the relatively higher doped inner portion while device shorting is limited by the relatively lower doped outer portion.
