    摘要: The fabrication of integrated circuits comprising resistors having the same structure but different sheet resistances is disclosed herein. In one embodiment, a method of fabricating an integrated circuit comprises: concurrently forming a first resistor laterally spaced from a second resistor above or within a semiconductor substrate, the first and second resistors comprising a doped semiconductive material; depositing a dopant receiving material across the first and second resistors and the semiconductor substrate; removing the dopant receiving material from upon the first resistor while retaining the dopant receiving material upon the second resistor; and annealing the first and second resistors to cause a first sheet resistance of the first resistor to be different from a second sheet resistance of the second resistor.

    摘要: In an aspect, a method is provided for forming a silicon-on-insulator (SOI) layer. The method includes the steps of (1) providing a silicon substrate; (2) selectively implanting the silicon substrate with oxygen using a low implant energy to form an ultra-thin patterned seed layer; and (3) employing the ultra-thin patterned seed layer to form a patterned SOI layer on the silicon substrate. Numerous other aspects are provided.

    摘要: A finFET structure and a method of fabricating the finFET structure. The method includes: forming a silicon fin on a top surface of a silicon substrate; forming a gate dielectric on opposite sidewalls of the fin; forming a gate electrode over a channel region of the fin, the gate electrode in direct physical contact with the gate dielectric layer on the opposite sidewalls of the fin; forming a first source/drain in the fin on a first side of the channel region and forming a second source/drain in the fin on a second side of the channel region; removing a portion of the substrate from under at least a portion of the first and second source/drains to create a void; and filling the void with a dielectric material. The structure includes a body contact between the silicon body of the finFET and the substrate.
