Abstract:
A method of manufacturing a semiconductor device having at least one thin film transistor, comprising the steps of:forming a semiconductor film to be crystallized on an insulating surface, said semiconductor film having a first portion;disposing a catalyst containing material on the first portion of the semiconductor film, said catalyst being capable of promoting crystallization of said semiconductor film wherein said first portion has a shape lengthened in a first direction;heating said semiconductor film so that a crystal growth proceeds from said first portion uniformly through a second portion of the semiconductor film adjacent to said first portion in a second direction substantially orthogonal to said first direction;patterning said semiconductor film into at least one island after the step of crystallization thereof, said island being formed within said second portion of the semiconductor film;forming source and drain regions in said island with a channel region defined therebetween so that a channel length direction extending between the source and drain regions intersects with said first direction to form an angle; andforming a gate electrode over said channel region.
