  • Patent number: 9876077
    Abstract: One illustrative method disclosed herein includes, among other things, forming a plurality of trenches in a semiconductor substrate so as to define a plurality of fins, forming a recessed layer of insulating material comprising a first insulating material in the trenches, wherein a portion of each of the plurality of fins is exposed above an upper surface of the recessed layer of insulating material, and masking a first portion of a first fin and performing at least one first etching process to remove at least a portion of an unmasked second fin. In this example, the method further includes forming a device isolation region for the FinFET device that comprises a second insulating material and forming an isolation protection layer above the device isolation region.

  • Patent number: 9831317
    Abstract: Structures including a vertical field-effect transistor and fabrication methods for a structure including a vertical field-effect transistor. A vertical field-effect transistor includes a source/drain region located in a section of a semiconductor layer, a first semiconductor fin projecting from the source/drain region, a second semiconductor fin projecting from the source/drain region, and a gate electrode on the section of the semiconductor layer and coupled with the first semiconductor fin and with the second semiconductor fin. The structure further includes a contact located in a trench defined in the section of the semiconductor layer between the first semiconductor fin and the second semiconductor fin. The contact is coupled with the source/drain region of the vertical field-effect transistor.

  • Publication number: 20150333128
    Abstract: Provided are methods of fabricating a semiconductor structure. The methods include providing a III-V semiconductor substrate selected from InGaAs and InAs, introducing an n-type dopant selected from S, Se, and Te directly onto a surface of the III-V semiconductor substrate, introducing a co-dopant selected from N and P directly onto a surface of the III-V semiconductor substrate, and diffusing the n-type and co-dopant into the III-V semiconductor substrate, thereby forming an n-doped III-V semiconductor substrate containing the n-type dopant and the co-dopant. The methods produce inventive semiconductor structures, and devices that include the semiconductor structure.
