Abstract: Disclosed is a tri-gate field effect transistor with a back gate and the associated methods of forming the transistor. Specifically, a back gate is incorporated into a lower portion of a fin. A tri-gate structure is formed on the fin and is electrically isolated from the back gate. The back gate can be used to control the threshold voltage of the FET. In one embodiment the back gate extends to an n-well in a p-type silicon substrate. A contact to the n-well allows electrical voltage to be applied to the back gate. A diode created between the n-well and p-substrate isolates the current flowing through the n-well from other devices on the substrate so that the back gate can be independently biased. In another embodiment the back gate extends to n-type polysilicon layer on an insulator layer on a p-type silicon substrate. A contact to the n-type polysilicon layer allows electrical voltage to be applied to the back gate.

Abstract: A horizontal germanium silicon heterostructure photodetector comprising a horizontal germanium p-i-n diode disposed over a horizontal parasitic silicon p-i-n diode uses silicon contacts for electrically coupling to the germanium p-i-n through the p-type doped and n-type doped regions in the silicon p-i-n without requiring direct physical contact to germanium material. The current invention may be optically coupled to on-chip and/or off-chip optical waveguide through end-fire or evanescent coupling. In some cases, the doping of the germanium p-type doped and/or n-type doped region may be accomplished based on out-diffusion of dopants in the doped silicon material of the underlying parasitic silicon p-i-n during high temperature steps in the fabrication process such as, the germanium deposition step(s), cyclic annealing, contact annealing and/or dopant activation.
