Abstract
A thin film transistor (TFT) of a self-aligned structure, wherein a pair of a source electrode and a drain electrode are formed in alignment with a gate electrode and in contact with low resistance areas formed at both side portions of a semiconductor layer deposited on an insulating substrate. The low resistance areas are formed by the diffusion of metal atoms through heat-treatment.
