Tunable FIN-SCR for robust ESD protection

Abstract:

One embodiment of the present invention relates to a silicon-controlled-rectifier (SCR). The SCR includes a longitudinal silicon fin extending between an anode and a cathode and including a junction region there between. One or more first transverse fins traverses the longitudinal fin at one or more respective tapping points positioned between the anode and the junction region. Other devices and methods are also disclosed.
