  • Patent number: 10566330
    Abstract: A CMOS system on chip including a series of partial gate-all-around field effect transistors. Each partial GAA FET includes a fin having a stack of channel regions, source and drain regions on opposite sides of the fin, a dielectric separation region including a dielectric material between first and second channel regions, a gate stack on the fin, and a pair of sidewall spacers on opposite sides of the gate stack. A portion of the dielectric separation region has a length from an outer edge of the dielectric separation region to an inner edge of a respective sidewall spacer. The length of the portion of the dielectric separation region of one of the partial GAA FETs is different than the length of the portion of the dielectric separation region of another one of the partial GAA FETs.
    Type: Grant

  • Patent number: 9741848
    Abstract: A Tunnel Field-Effect Transistor (TFET) is provided comprising a source-channel-drain structure of a semiconducting material. The source-channel-drain structure comprises a source region being n-type or p-type doped, a drain region oppositely doped than the source region and an intrinsic or lowly doped channel region situated between the source region and the drain region. The TFET further comprises a reference gate structure covering the channel region and a source-side gate structure aside of the reference gate structure wherein the work function and/or electrostatic potential of the source-side gate structure and the reference work function and/or electrostatic potential of the reference gate structure are selected for allowing the tunneling mechanism of the TFET device in operation to occur at the interface or interface region between the source-side gate structure and the reference gate structure in the channel region.
