Abstract

TFT-LCD requires to use poly silicon for High resolution and High integration. Thin film make of Poly silicon on the excimer laser-induced crystallization of PECVD(plasma-enhanced chemical vapor deposition)-grown amorphous silicon. In the thin film hydrogen affects to a device performance from bad elements like eruption, void and etc. So dehydrogenation prior to laser exposure was necessary. In this study, use RTP(Rapid Thermal Process) at various temperature from $670^{\circ}C$ to $750^{\circ}C$ and fabricate poly-silicon. it propose optimized RTP window to compare grain size to use poly silicon's SEM pictures and crystallization to analyze Raman curved lines.
