Abstract:
A method of fabricating a thin film transistor, the method comprising the steps of:forming a semiconductor layer on a substrate, said semiconductor layer having a first region, a channel region and a second region;forming a gate insulating layer and a gate electrode on said channel region;doping said first and said second regions with impurity of a first concentration;forming a metal film pattern to form a metal-offset region in said first region; andcrystallizing, said semiconductor layer by applying thermal treatment to said semiconductor layer having said metal film,wherein the step of forming the metal film pattern includes the steps of:forming a photoresist pattern covering a part of said first and said gate regions;forming a metal film on a whole surface of said substrate and said photoresist pattern; andremoving said photoresist pattern by lift-off to form a metal-offset region in said certain part of said first region.
