International Classification:

H01L 21/336
H01L 29/76

US Classification:

438283, 438284, 257365, 257401, 257623

Abstract:

A process is described for manufacturing of non-planar multi-corner transistor structures. A fin of a semiconductor material having a mask on a top surface of the fin is formed on a first insulating layer. A second insulating layer is formed on the fin exposing a top surface of the mask, wherein a protection layer is deposited between the fin and the second insulating layer. Next, the mask is removed and spacers are formed on the fin adjacent to the protection layer. A recess having a bottom and opposing sidewalls is formed in the fin. A gate dielectric layer and a gate electrode are formed on the top surface, the opposing sidewalls of the fin and on the bottom and on the opposing sidewalls of the recess in the fin. A source region and a drain region are formed in the fin at the opposite sides of the gate electrode.

Abstract:

The various embodiments utilize cascode circuits in dual-threshold-voltage (dual-V. sub. T), BiCMOS and DTMOS technologies. The circuit topologies include cascode-connected transistors in the output branch of a current mirror and as a cascode amplifier. Such configurations are capable of both high output impedance and high output swing. The cascode circuits of the various embodiments are operable without separate gate-bias voltages for the cascode-connected transistors. The current mirrors can be used in circuits requiring a regulated current or other current mirroring applications. The current mirrors can further be used as active loads, such as an active load for an amplifier.
