    摘要: An SRAM includes a substrate containing a plurality of first substrate regions and a plurality of second substrate regions, a plurality of pull-down transistors formed in the first substrate regions with each pull-down transistor including a first gate structure, and a plurality of pass-gate transistors formed in the second substrate regions with each pass-gate transistor including a second gate structure. A portion of the first substrate region under each first gate structure is doped with first doping ions and a portion of the second substrate region under each second gate structure is doped with second doping ions. Moreover, the concentration of the first doping ions is less than the concentration of the second doping ions, and the work function of the first work function layer in the first gate structures is greater than the work function of the second work function layer in the second gate structures.

    摘要: A Tunnel Field-Effect Transistor (TFET) is disclosed 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 a 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.
