Abstract

Disclosed are a self-aligned thin film transistor controlling a diffusion length of a doping material using a doping barrier in a thin film transistor having a self-aligned structure and a method of manufacturing the same. The self-aligned thin film transistor with a doping barrier includes: an active layer formed on a substrate and having a first doping region, a second doping region, and a channel region; a gate insulating film formed on the channel region; a gate electrode formed on the gate insulating film; a doping source film formed on the first doping region and the second doping region; and a doping barrier formed between the doping source film and the first doping region and between the doping source film and the second doping region.
