Abstract

We report on the characteristics of polycrystalline silicon (polysilicon) thin film transistors (TFTs) fabricated with low temperature crystallized LPCVD amorphous silicon film as an active layer and plasma enhanced chemical vapor deposition (PECVD) SiO2 as a gate insulator. High performance transistor characteristics are achieved, even though no process temperature exceeds 600°C. No threshold drift has been observed. As a result, these devices are highly suitable for application to image scanners as well as flat panel displays.
