Abstract: A thin film transistor and a fabricating method for a thin film transistor is disclosed which may be suitable for memory cells of a static random access memory (SRAM) or other devices. A thin film transistor according to this invention may include an insulation substrate, a gate electrode formed to have a negative slope at one side thereof on the insulation substrate, an insulation film side wall formed at the other side of the gate electrode, a gate insulation film formed on the insulation substrate, gate electrode and side wall, a semiconductor layer formed on the gate insulation film, impurity diffusion regions selectively formed within the semiconductor layer over the gate electrode, the side wall and the insulation substrate on the other side of the gate electrode, and a channel region formed within the semiconductor layer at the side of the gate electrode having the negative slope.

Abstract: A thin film transistor and a method which forms a channel region (c), a lightly doped drain region (LDD) region and, optionally, an offset region (o), in a portion of a semiconductor layer which is adjacent a sidewall of the gate electrode without the use of photo masks, thereby increasing the permissible degree of miniaturization and improving production yield.
