摘要：The effects of the source and drain junction depth on breakdown voltage of high-performance Si TFTs have been studied.It is found that decreasing the junction depth results in a substantial increase in the sourcedrain breakdown voltage (VBD).The improvement in VBD is primarily due to suppression of parasitic bipolar gain.Reduced parasitic bipolar gain originates from the suppression of the body potential elevation in the shallow junction structure,that allows for penetration of the excess holes beneath the source n+ region.
