This letter first reports the characteristics of polyoxide that was thermally grown on polished polysilicon film. Compared to conventional polyoxide, polyoxide grown on polished polysilicon film exhibits lower leakage current, higher dielectric breakdown field, larger effective barrier height, and higher charge-to-breakdown. This simple and well-operated process provides a very promising option for the interpolysilicon oxide.
