摘要： An LCD is adapted to be manufactured using a significantly reduced number of masks and masking processes. In order to form a gate of the LCD, aluminum and one of molybdenum, tantalum, tungsten and antimony are sequentially deposited and patterned using a single mask. Cutting a shorting bar for preventing static electricity is performed while a passivation layer is patterned and rinsed. Accordingly, an LCD produced by this method includes a first metal layer, which includes a first contact hole and is disposed on a substrate, a second metal layer which covers the first metal layer and includes a second contact hole which is smaller than the first contact hole, an insulating layer, which covers the second metal layer and includes a third contact hole larger than the second contact hole, and a pad, which includes a conductive layer contacting the second metal layer through the third contact hole on the insulating layer.

摘要： Disclosed is a thin film transistor substrate for a fringe filed switching type liquid crystal display device, and a fabrication method thereof, that reduces the number of required mask processes, and thus improves fabrication efficiency. The fabrication method involves three mask processes, wherein the masks are partial transmitting masks, and the resulting photo-resist patterns have varying thicknesses. By having photo-resist layers of varying thicknesses, structures can be formed in multiple etching steps using the same photo-resist pattern by incrementally removing the photo-resist according to its thickness. The thin film transistor substrate has a common line, a common electrode, a gate line and a gate electrode formed directly on the substrate. The common electrode overlaps the pixel electrode in the pixel area.

摘要： An X-ray detecting device and a fabricating method thereof capable of preventing a short between a lower electrode of a capacitor and a data line are presented. In the device, a data line insulating layer is formed to cover the data line and a gate line. The gate line is exposed through a contact hole defined in the data line insulating. Then a lower electrode is formed on the data line insulating layer and is electrically connected to the gate line via the contact hole. Subsequently, an upper electrode is formed to complete the device. The data line insulating layer prevents a short between the data line and the lower electrode when residual conductive materials are formed when the lower electrode is formed.
