  • Reduced footprint LDMOS structure for finFET technologies
    Patent number: 9698148
    Abstract: A field effect transistor (FET) having one or more fins provides an extended current path as compared to conventional finFETs. A source terminal is disposed on a first fin between a first dummy gate and a gate structure. A drain terminal is disposed on a second fin between a second dummy gate and a third dummy gate. A first gate oxide layer disposed under second and third dummy gates is made to be thinner than a second gate oxide layer disposed under the first dummy gate and the gate structure. By making the first gate oxide layer thinner, an overall footprint of the finFET device is reduced.
