Abstract:
A first patterned conductive layer is formed on a substrate. A dielectric layer, a semiconductor layer, a second conductive layer and a photoresist layer are formed above the first patterned conductive layer. The photoresist layer is patterned using a photomask with multiple different transparencies, and the patterned photoresist layer has at least three different thicknesses. The photoresist layer within the channel region is removed. The second conductive layer within the channel region and part of semiconductor layer are etched to form a channel, source and drain of a thin film transistor. The photoresist layer corresponding to a pixel connecting region and a data pad region is removed to expose a pixel connecting region and a data pad. The remained photoresist layer is reflowed so as to cover the channel. The uncovered semiconductor layer is removed using the reflowed photoresist layer and the patterned second conductive layer as a mask.

The subject invention provides a relatively simple and time-saving method for producing an array substrate.

Abstract:
A method for manufacturing a pixel structure is provided. A gate and a gate insulating layer are sequentially formed on a substrate. A semiconductor layer and a second metal layer are sequentially formed on the gate insulating layer. The semiconductor layer and the second metal layer are patterned to form a channel layer, a source and a drain by using a patterned photoresist layer formed thereon, wherein the source and drain are disposed on a portion of the channel layer. The gate, channel, source and drain form a thin film transistor. A passivation layer is formed on the patterned photoresist layer, the gate insulating layer and the thin film transistor. Then, the patterned photoresist layer is removed, such that the passivation layer thereon is removed simultaneously to form a patterned passivation layer and the drain is exposed. A pixel electrode is formed on the patterned passivation layer and the drain.
