Abstract
A semiconductor doping method includes steps of forming an insulation layer on a substrate, forming a semiconductor layer on the insulation layer, forming a photoresist layer on the insulation layer, patterning the photoresist layer to provide a portion of the photoresist layer on a first portion of the semiconductor layer, hard baking the portion of the photoresist layer at a first hard-baking temperature of more than about 140° C., doping the semiconductor layer with an impurity in regions other than the first portion of the semiconductor layer, and removing the portion of the photoresist layer.
