Abstract:
A process for producing a display comprising the steps of:forming a crystalline semiconductor film by a process comprising: a semiconductor film deposition process in which a semiconductor film is deposited on a substrate, a first annealing process in which said semiconductor film is crystallized by repeatedly performing a process that melt crystallizes a portion of said semiconductor film, and a second annealing process in which rapid thermal annealing is performed on said crystallized semiconductor film, wherein an annealing temperature in the second annealing process is expressed by the absolute temperature T and, when the annealing time is t, expressed in seconds, annealing temperature T and annealing time t satisfy the relationship: 1.72Ã—10âˆ’21secÂ·exp(âˆ’&egr;/kT)<4.63Ã—10âˆ’14sec wherein &egr;=3.01eV and k=8.617Ã—10âˆ’5eV/K; and forming a panel equipped with a device using the semiconductor film.
