Abstract

Fashioning a low noise (1/f) junction field effect transistor (JFET) is disclosed, where multiple implants are performed to push a conduction path of the transistor away from the surface of a layer upon which the transistor is formed. In this manner, current flow in the conduction path is less likely to be disturbed by defects that may exist at the surface of the layer, thereby mitigating (1/f) noise.
