Abstract:
1. A method for manufacturing an organic light emitting diode (OLED) display, comprising: forming a polycrystalline silicon layer on a substrate; reducing or eliminating a native oxide at a surface of the polycrystalline silicon layer by etching using a first atmospheric pressure plasma generated by plasmatizing fluorine-containing gas; reducing or eliminating organic and metal contaminants at the surface of the polycrystalline silicon layer using a second atmospheric pressure plasma generated by plasmatizing oxygen-containing gas; forming a semiconductor layer by patterning the polycrystalline silicon layer; forming a gate insulating layer and a gate electrode on the semiconductor layer; forming a channel area, a source area, and a drain area in the semiconductor layer by impurity doping; forming an interlayer insulating layer on the gate electrode; forming a source electrode coupled with the source area on the interlayer insulating layer; forming a drain electrode coupled with the drain area on the interlayer insulating layer; forming a pixel electrode coupled with the drain electrode; and forming an organic emission layer and a common electrode on the pixel electrode.
