Patent ID: 8216891

Claim:
A method for fabricating a thin film transistor (TFT) array plate for use in a liquid crystal display, comprising: forming a transparent conductive layer on a substrate; forming a patterned photoresist on the transparent conductive layer; patterning the transparent conductive layer and the substrate with the patterned photoresist to form at least one scanning trench and at least one capacitive trench arranged alternately in parallel, wherein the at least one scanning trench has at least one TFT area, at least one scanning area, and at least one first terminal area, and the at least one capacitive trench has at least one capacitive area and at least one second terminal area; sequentially forming a first metal layer, a dielectric layer, a silicon layer, and a doped silicon layer only in the at least one scanning trench and the at least one capacitive trench, respectively; removing the patterned photoresist; forming a second metal layer on the doped silicon layer and the transparent conductive layer; and simultaneously defining a TFT in the TFT area, a storage capacitor and a data line in the capacitive area, and two terminal structures in the first and the second terminal areas by a photolithography and an etching process with a single exposure step.
