Patent ID: 7659153

Claim:
A method for producing a field effect device, said method comprises: providing a first layer of a crystalline semiconductor material, wherein said first layer is disposed on an insulator layer; fabricating a formation, said formation comprises a second layer and a wall, wherein said second layer is disposed on said first layer and said wall is standing on said second layer, wherein said second layer and said wall are of differing materials, wherein during said fabrication of said wall said first layer and said insulator layer are of approximately equal dimension in a horizontal direction, and wherein said formation represents a pattern; and etching said second layer and said first layer until said pattern of said formation is transferred into said first layer, wherein leaving in place of said first layer only a kernel consisting of said crystalline semiconductor material, wherein said kernel comprises a body, wherein said body has at least one vertically oriented section and at least one horizontally oriented section, wherein said wall yields said at least one vertically oriented section and said second layer of said formation yields said at least one horizontally oriented section, and wherein said device comprises said body.
