A semi-SOI MOSFET produced by drain/source oxygen implantation can suppress self-heating effect and improve breakdown voltage. However owing to the complicated 2-D electric field distribution
the threshold voltage
the sub-threshold slope and the SCEs (short channel effects) of OISD MOSFET are modulated by the size of the silicon window. A compact threshold voltage model based on 2-D numerical simulation was provided for OISD MOST design. At last the threshold voltage model was verified and several other important electrical parameters
including sub-threshold slope
DIBL factor and SCEs
were analyzed in details with the help of MEDICI 2D simulator.
