Abstract :
The laser-recrystallized SOI (silicon-on-insulator) method was used to fabricate 0.8-μm SOI MOSFETs in which the mesa isolation technique was used. The process finished SOI thickness and gate oxide thickness were 450 nm and 20 nm. The electrical characteristics of the MOSFETs at the position of 20 μm from seed with a gate length of 0.8 μm and a channel width of 10 μm are shown. Uniformity of the SOI MOSFET characteristics was almost the same as that of bulk MOSFETs. Results for a CMOS ring oscillator without any additional load capacitance are shown. The delay time was 117 ps/stage and supply voltage of 5 V. This indicated that the speed performance was also improved by the improved transistor characteristics and was comparable to that of the bulk Si case
