Thin film transistor having a patterned passivation layer
First Claim
1. A thin film transistor, comprising:
- a substrate;
a gate, disposed on the substrate;
a gate insulating layer, disposed on the gate;
a source and a drain, disposed on the gate insulating layer, wherein the source, the drain and the gate insulating layer together form a hollow;
a channel layer, disposed under the source and the drain, wherein a portion of the channel layer is exposed by the hollow between the source and the drain;
a first patterned passivation layer, disposed completely within the hollow and contacting the portion of the channel layer, wherein the first patterned passivation layer includes a metal oxide, the first patterned passivation layer has a thickness ranging from 50 angstroms to 300 angstroms; and
a second patterned passivation layer, covering the first patterned passivation layer and disposed within the hollow.

Abstract
A thin film transistor is provided. The thin film transistor includes a substrate, a gate, a gate insulating layer, a source and a drain, a channel layer, and first and second patterned passivation layers. The gate is disposed on the substrate. The gate insulating layer is disposed on the gate. The source and the drain are disposed on the gate insulating layer. The channel layer is disposed above or under the source and the drain, wherein a portion of the channel layer is exposed between the source and the drain. The first patterned passivation layer is disposed on the portion of the channel layer, wherein the first patterned passivation layer includes metal oxide, and the first patterned passivation layer has a thickness ranging from 50 angstroms to 300 angstroms. The second patterned passivation layer covers the first patterned passivation layer, the gate insulating layer, and the source and the drain.
