Patent ID: 7011995

Claim:
A method of fabricating a semiconductor device comprising a plurality of thin film transistors, the method comprising: forming a base film on a substrate; forming a semiconductor film on the base film; providing a solution containing a catalytic element for promoting a crystallization of the semiconductor film on the semiconductor film; crystallizing the semiconductor film provided with the solution by a heat treatment; and removing the catalytic element in the crystallized semiconductor film; and etching the crystallized semiconductor film into a plurality of semiconductor layers, each having at least a channel region for a thin film transistor, wherein the channel region comprises at least one selected from the group consisting of {110}, {211}, {321}, {431}, {532} and {541} plane orientation; and wherein a standard deviation of a population of a collective of subthreshold coefficients exhibited by the plurality of the respective thin-film transistors is 10 mV/dec or less.
