Abstract: A thin filmed fully-depleted silicon-on-insulator (SOI) metal oxide semiconductor field defect transistor (MOSFET) utilizes a local insulation structure. The local insulative structure includes a buried silicon dioxide region under the channel region. The MOSFET body thickness is very small and yet silicon available outside of the channel region and buried silicon dioxide region is available for sufficient depths of silicide in the source and drain regions. The buried silicon dioxide region can be formed by a trench isolation technique or a LOCOS technique.

Abstract: A method of manufacturing a MOSFET semiconductor device includes forming a gate electrode over a substrate and a gate oxide between the gate electrode and the substrate, forming source/drain extensions in the substrate, and forming first and second sidewall spacers. Dopants are then implanted within the substrate to form amorphitized source/drain regions in the substrate adjacent to the sidewalls spacers. The amorphitized source/drain regions are partially recrystallized, and laser thermal annealing activates the source/drain regions. The source/drain extensions and sidewall spacers are adjacent to the gate electrode. The source/drain extensions can have a depth of about 50 to 300 angstroms, and the source/drain regions can have a depth of about 400 to 1000 angstroms. Also, the recrystallization reduces the amorphitized source/drain regions by a depth of about 20 to 100 angstroms. A semiconductor device is also disclosed.
