Abstract
A thin-film transistor (TFT) with body contacts is disclosed. It is used in polysilicon TFT LCD's. A body contact region for separating the gate electrode, a source region, and a drain region is made in the TFT. Through the dopants in the body contact region and different impurities in the source region and the drain region, a body-trigger bias is imposed on the body of the TFT. This method reduces the threshold voltage of the TFT driving circuit, thereby increasing the driving current.
