Abstract:
1. A method of making microelectronic structure, comprising: disposing a dielectric superjacent a top surface of a substrate having a first conductivity type; disposing a gate electrode superjacent the dielectric; and forming a source terminal and a drain terminal of a first single crystal epitaxial film and a second single crystal epitaxial film, wherein the first single crystal epitaxial film is of said first conductivity type and is formed below the top surface of said substrate and partially underlies the gate electrode, and the second single crystal epitaxial film is formed over the first single crystal epitaxial film and is of a second conductivity type and partially underlies the gate electrode, wherein the first single crystal epitaxial film and the second single crystal epitaxial film are substantially free of counterdopants.
