摘要: 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.

摘要: A method for fabricating a pixel structure includes following steps. First, a substrate is provided. Next, a first conductive layer is formed on the substrate. Next, a first shadow mask is disposed over the first conductive layer. Next, a laser is applied through the first shadow mask to irradiate the first conductive layer to form a gate. Next, a gate dielectric layer is formed on the substrate to cover the gate. After that, a channel layer, a source and a drain are simultaneously formed on the gate dielectric layer over the gate, wherein the gate, the channel layer, the source and the drain together form a thin film transistor. A patterned passivation layer is formed on the thin film transistor and the patterned passivation layer exposes a part of the drain.

摘要: A method of fabricating a pixel structure including the following procedures is provided. First, a substrate having an active device thereon is provided. A patterned passivation layer is formed on the substrate and the active device, and the patterned passivation layer exposes a portion of the active device. Then, a conductive layer is formed over the patterned passivation layer, and the conductive layer is electrically connected to the active device. A mask exposing a portion of the conductive layer is provided above the conductive layer. A laser is used to irradiate the conductive layer via the mask to remove the portion of the conductive layer exposed by the mask. As a result, the remained portion of the conductive layer constitutes a pixel electrode, and the pixel electrode is electrically connected to the active device. The method simplifies the fabrication process of a pixel structure, and thus reduces the fabrication cost.
