Metal Oxide Semiconductor Field Effect Transistor (MOSFET) plays a key role in electronic industry in recent years. Among MOSFETs, double gate (DG) transistor is an important device. During last decade, many efforts have been accomplished to improve the device properties. A new structure of the double gate (DG) transistor on SOI technology is proposed in this paper. In SOI technology, buried oxide as insulating layer has lower thermal conductivity than silicon and makes some problems for nano-scale MOSFETs. Incorporating a silicon window under the channel region and two spacers reduces maximum temperature of device. The simulation with ATLAS simulator shows that by optimizing the length and thickness of the silicon window, an acceptable device temperature would be achieved and makes the double gate structure more reliable for nano-scale applications at high temperature. Drain current, lattice temperature, electron mobility, hole density, threshold voltage, subthreshold swing and off current are improved in the new structure.
