Photo-thermal annealing (PTA) was utilized for solid-phase crystallization
of amorphous silicon films below 600 degrees C. Amorphous silicon was depos
ited by plasma enhanced chemical vapor deposition (PECVD) and annealed by t
ungsten halogen lamps heating. The PTA process can crystallize amorphous si
licon in less duration, with lower thermal budget than traditional furnace
annealing. The role of photons in facilitating crystallization was given sp
ecial attention. Application of the material to electronic devices such as
solar cells and thin film transistors (TFT) is the aim of our research. (C)
