Patent ID: 8203182

Claim:
A Fin field effect transistor, FinFET, comprising a fin-shaped layer-section of a single-crystalline active semiconductor layer extending on an insulating substrate layer along a longitudinal fin direction between a source layer-section and a drain layer-section of the single-crystalline active semiconductor layer, gate insulation layers arranged on two opposite side faces of the fin-shaped layer-section, and two separate gate-electrode layers, which do not form sections of the single-crystalline active semiconductor layer, each of the gate-electrode layers facing one of the opposite side faces of the fin-shaped layer-section, and each gate-electrode layer being connected with a respective separate gate contact, wherein each of the gate-electrode layers, as seen in a cross-sectional view of a plane that is perpendicular to the longitudinal fin-direction, is arranged on the substrate layer between the respective side face of the fin-shaped layer section and a respective contact-post layer section of the single-crystalline semiconductor layer; wherein the gate contacts are arranged abutting a top face of the respective contact-post layer section of the single-crystalline active semiconductor layer and a side face of the respective gate-electrode layer.
