摘要:
A thin film transistor and a method for manufacturing the same are provided. A top-gate thin film transistor is fabricated by a process using two gray-tone photomasks and a lift-off method. Therefore, the method can save cost of photomasks and processes comparing to a conventional fabrication method.
摘要:
A method of manufacturing a thin film transistor array substrate and a structure of the same are disclosed. The manufacturing method merely requires two steps of mask fabrication to accomplish the manufacture of thin film transistor array, in which the manufacturing method utilizes a first mask fabrication step to define a pattern of a source electrode and a drain electrode of the thin film transistor, and a partially-exposed dielectric layer, and utilizes a second mask fabrication step to define an arrangement of a transparent conductive layer. The manufacturing method and structure can dramatically reduce the manufacturing cost of masks and simplify the whole manufacturing process.
摘要:
The present invention relates to a method for forming a contact opening. First, a substrate having at least a dielectric layer formed thereon is provided. Then, a photoresist layer having a first opening is formed on the dielectric layer. A plasma etching operation is performed to form a second opening in the dielectric layer, and the first opening is located above the second opening. The bottom part of the first opening has a diameter smaller than that of the top part of the second opening. Thereafter, the photoresist layer is removed from the dielectric layer. Accordingly, at least a portion of the exposed contact opening will not be oxidized to prevent an increase in the resistance between the conductive pattern and the conductive layer that fills in the contact opening.

摘要:
A method of forming a thin-film transistor array substrate is provided. A first mask is used to define a source, a drain and a channel on a substrate. A dielectric layer is formed to cover the source, the drain, the channel and the substrate. A second mask is used to define a patterned photoresist and the dielectric layer. A transparent conductive layer is formed to cover the patterned photoresist and the substrate. A lift-off process is performed to remove the patterned photoresist and a portion of the transparent conductive layer disposed on the patterned photoresist. A third mask is used to define a gate disposed on the dielectric layer.
