    • A method for fabricating a BCE type TFT array by using reduced number of masks and devices formed are disclosed. In the method, only five masks are required for forming the BCE type TFT array which is less than that normally required in a typical TFT fabrication process, i.e., at least six masks. The five masks required in the present invention process are a first mask for gate busline patterning, a second mask for island and S/D data line patterning, a third mask for the data line, TFT channel and Cst patterning, a fourth mask for the passivation layer patterning and a fifth mask for the conductive electrode layer patterning. The present invention novel method produces a TFT that has improved contact resistance between the S/D metal and the n+ amorphous silicon layer. The improved contact resistance is achieved by an immediate deposition process of a S/D metal thin film after the deposition of the n+ amorphous silicon layer such that any exposure of the interface to chemical contaminants and native oxide is substantially reduced or eliminated. The present invention novel method further provides the benefit that the Metal 2 layer shields the TFT island structure from plasma damages and residual photoresists resulting in a TFT array structure of improved reliability.
    • 公开了一种通过使用减少数量的掩模和形成的器件来制造BCE型TFT阵列的方法。 在该方法中,形成BCE型TFT阵列仅需要五个掩膜,其小于通常在TFT制造工艺中通常所需的掩模,即至少六个掩模。 在本发明方法中所需的五个掩模是用于栅极总线图案化的第一掩模,用于岛和S / D数据线图案化的第二掩模,用于数据线的第三掩模,TFT沟道和Cst图案化,第四掩模 钝化层图案化和用于导电电极层图案化的第五掩模。 本发明新颖的方法产生了在S / D金属和n +非晶硅层之间具有改善的接触电阻的TFT。 改善的接触电阻通过在沉积n +非晶硅层之后立即沉积S / D金属薄膜来实现,使得界面对化学污染物和天然氧化物的任何暴露显着降低或消除。 本发明的新颖方法还提供了金属2层屏蔽TFT岛结构免受等离子体损伤和残留光致抗蚀剂的益处,导致提高可靠性的TFT阵列结构。

    • A thin film transistor design is described which is not subject to either dark or photo current leakage. The process to manufacture this device begins with the formation of a gate electrode on a transparent substrate followed by its over coating with layers of gate insulation, undoped amorphous silicon, doped amorphous silicon, and a second layer of chromium. The chromium and amorphous silicon layers are then patterned and etched to form a channel pedestal. In a key feature of the invention the vertical side walls of this pedestal are then given a protective coating of oxide or nitride, forming spacers. This is then followed by the deposition of second level metal which is etched to form source and drain electrodes with a suitable gap between them.
