Abstract:
A solid phase crystallization method of the present invention includes: providing amorphous silicon; heating the amorphous silicon to a first crystallization temperature; continuously heating the amorphous silicon to cause a temperature rise, in a first time period, from the first crystallization temperature to a second crystallization temperature, keeping the amorphous silicon in the second crystallization temperature for a predetermined time interval, causing a temperature drop of the amorphous silicon so as to gradually drop, in a second time period, from the second crystallization temperature to the first crystallization temperature, allowing continuous temperature drop of the amorphous silicon to reach the room temperature to thereby obtain low-temperature poly-silicon. The differences of temperature among various areas can be reduced when amorphous silicon starts to crystallize so that the difference of crystal nuclei growth rate among the various areas can be reduced to greatly improve homogeneity of grains formed through solid phase crystallization.

Claim (Index 4):
The solid phase crystallization method according to  claim 3 , wherein the first time period and the second time period are both 5 min, and the time interval for keeping the amorphous silicon in the second crystallization temperature is 60 min.
