  • Patent number: 10680088
    Abstract: A tunnel field effect transistor (TFET) device includes a substrate, heavily doped source and drain regions disposed at opposite ends of a channel region forming a PiN or NiP structure, the channel region including a first substantially parallelogram portion having a first length defined along a longitudinal axis extending from the source region to the drain region and a second substantially parallelogram portion having a second length defined along the longitudinal axis larger than the first length, the TFET device having an effective channel length that is an average of the first and second lengths. The channel region includes a channel material with a first effective mass along a longitudinal axis extending from the source region to the drain region and a second effective mass along a lateral axis perpendicular to the longitudinal axis, the first effective mass being greater than the second effective mass.

  • Publication number: 20180254335
    Abstract: A tunnel field effect transistor (TFET) device is disclosed. The TFET includes a substrate, heavily doped source and drain regions disposed at opposite ends of the substrate separated by a channel region forming a PiN or NiP structure, the channel region including a first substantially parallelogram portion having a first length defined along a longitudinal axis extending from the source region to the drain region and a second substantially parallelogram portion having a second length defined along the longitudinal axis larger than the first length, the TFET device having an effective channel length defined along the longitudinal axis that is an average of the first and second lengths. The channel region includes a channel material with a first effective mass along a longitudinal axis extending from the source region to the drain region and a second effective mass along a lateral axis perpendicular to the longitudinal axis.
