  • Patent number: 11756823
    Abstract: A semiconductor-on-insulator (SOI) transistor includes a semiconductor layer situated over a buried oxide layer, the buried oxide layer being situated over a substrate. The SOI transistor is situated in the semiconductor layer and includes a transistor body, gate fingers, source regions, and drain regions. The transistor body has a first conductivity type. The source regions and the drain regions have a second conductivity type opposite to the first conductivity type. A heavily-doped body-implant region has the first conductivity type and overlaps at least one source region. A common silicided region electrically ties the heavily-doped body-implant region to the at least one source region. The common silicided region can include a source silicided region, and a body tie silicided region situated over the heavily-doped body-implant region. The source silicided region can be separated from a drain silicided region by the gate fingers.
