A process for making a MCSFET includes providing a first implant through a first side of an elongated stack, and then providing a second implant through a second side of the stack. The first implant has a dose different than the dose of the second implant, so that final dopant concentrations in the first and second sides differ and the transistor has two threshold voltages Vt1, Vt2.
