摘要:
A method for manufacturing a thin film transistor array panel, including: sequentially forming a first silicon layer, a second silicon layer, a lower metal layer, and an upper metal layer on a gate insulating layer and a gate line; forming a first film pattern on the upper metal layer; forming a first lower metal pattern and a first upper metal pattern that includes a protrusion, by etching the upper metal layer and the lower metal layer; forming first and second silicon patterns by etching the first and second silicon layers; forming a second film pattern by ashing the first film pattern; forming a second upper metal pattern by etching the first upper metal pattern; forming a data line and a thin film transistor by etching the first lower metal pattern and the first and second silicon patterns; and forming a passivation layer and a pixel electrode on the resultant.
摘要:
A thin film transistor array panel includes a source electrode and a drain electrode composed of a Mo alloy layer and a Cu layer, and an alloying element of the Mo alloy layer forms a nitride layer as a diffusion barrier against the Cu layer. The nitride layer can be formed between the Mo alloy layer and the Cu layer, between the Mo alloy layer and the semiconductor layer or in the Mo alloy layer. A method of fabricating a thin film transistor array panel includes forming a data line having a first conductive layer and a second conductive layer, the first conductive layer containing a Mo alloy and the second conductive layer containing Cu, and performing a nitrogen treatment so that an alloying element in the first conductive layer forms a nitride layer. The nitrogen treatment can be performed before forming the first conductive layer, after forming the first conductive layer, or during forming the first conductive layer.
