Patent ID: 7385247

Claim:
An at least penta-sided-channel type of FinFET transistor comprising: a base including, a base semiconductor structure having a fin extending perpendicularly therefrom and shoulder portions above which the fin extends, and one or more isolation regions formed on the base semiconductor structure, the one or more isolation regions extending above the fin so as to define a recess in the one or more isolation regions above the fin; a semiconductor body formed on the base, the semiconductor body being arranged in a long dimension to have source/drain regions sandwiching a channel region, the semiconductor body having a stalk portion extending down into and at least partially filling the recess, wherein the channel region has at least five planar surfaces above the base, at least two of the planar surfaces being beveled surfaces; a gate insulator on the channel region of the body; and a gate electrode formed on the gate insulator.
