Abstract

The floating body induced transient characteristics in polycrystalline silicon TFTs is reported. An obvious current surge, arising from the floating body effect, is observed. Using a 2D numerical simulator and comparisons to SIMOX FETs, the insight into the mechanisms governing the experimentally observed switching behavior of poly-Si devices is obtained. It is found that the defect states in poly-Si cause the current surge and exert an effect equivalent to doping in SIMOX FETs.
