Improvement of electrical characteristics for novel process-compatible floating channel solid-phase crystallized poly-Si TFTs

Abstract

High-performance polycrystalline-silicon thin-film transistors (poly-Si TFTs) with floating channel solid-phase crystallization are proposed for the first time. By adopting this novel crystallization scheme, a better crystalline poly-Si film can be obtained in the suspended channel film. Poly-Si TFTs with this novel floating channel structure have been successfully fabricated and the experimental results demonstrate a superior electrical performance and reliability.
