Abstract:
1. A method of manufacturing an organic light emitting diode display, comprising: forming a first silicon layer and a second silicon layer over a substrate; forming an insulating layer over the first silicon layer and the second silicon layer; forming a lower metal layer over the insulating layer and an upper metal layer over the lower metal layer; forming a photoresist pattern over the upper metal layer; dry-etching the upper metal layer by using the photoresist pattern to form a first upper metal portion and a second upper metal portion; wet-etching the lower metal layer using the photoresist pattern to form a first lower metal portion and a second lower metal portion; and doping conductive impurity ions to the first silicon layer and the second silicon layer to form a semiconductor comprising a source region, and a drain region, and a first capacitor electrode; wherein the first upper metal portion comprises a doping opening exposing the first lower metal portion, and wherein the conductive impurity ions are doped to the second silicon layer through the doping opening.
