A lateral polysilicon Bipolar Charge Plasma Transistor (poly-Si BCPT) on undoped recrystallized polycrystalline silicon which is compatible with the thin-film field effect transistor (TFT) fabrication is reported in this paper. Using calibrated two-dimensional device simulation, the electrical performance of the poly-Si BCPT is evaluated in detail by considering the position of the single grain boundary. Our simulation results demonstrate that the poly-Si BCPT has the potential to realize low-cost thin-film polycrystalline silicon bipolar transistors with large current gain and cut-off frequency making it suitable for a number of applications including the driver circuits of the displays.
