摘要：

A standard CMP (Chemical Mechanical Polishing) process has been used to reduce surface roughness of polysilicon thin film N-channel TFT ha; been fabricated on both polished and unpolished polysilicon thin film. Both thin thermally grown and deposited oxides with thickness under 30nm are used as the gate dielectric. It is founded that TFT fabricated on polished polysilicon thin film exhibits higher carrier mobility, better sub-threshold swing, lower threshold voltage, higher on/off current ratio as well as better ability to withstand high voltage operation and longer device lifetime. Such improvement should benefit applications which incorporate TFT such as SRAM and LCD display.
