Abstract: PURPOSE: A liquid crystal display is provided to increase the capacitance value of a storage capacitor and the aperture ratio by reducing the width of a black matrix and perform repair function when a data line is open. CONSTITUTION: A storage capacitor(18) for preventing the voltage variation of a pixel electrode(14) charges voltage when a gate high voltage is applied to a gate line(4) and discharges the charged voltage when a data signal is applied to the pixel electrode(14). A gate dummy pattern(30) performs the role of a black matrix and repair function on the open of a data line(2) because it is superposed with the data line(2) and the pixel electrode(14) adjacent to the date line(2). Exactly, the gate dummy pattern(30) shields the light leaked between the data line(2) and the pixel electrode(14). The gate dummy pattern(30) is used as a storage electrode for forming a storage capacitor together with the pixel electrode(14) charged between a gate insulator layer and a passivation layer when it is connected with the gate line(4) electrically. Therefore, the voltage of the pixel electrode(14) is maintained more stably because the capacitance value of the storage capacitor caused by the gate dummy pattern is added to the storage capacitor(18).

IPC: H01L21/762
Filed: 1999-11-29
Abstract: PURPOSE: A box isolation technique for integrated circuit structures is provided to utilize implanted oxygen to form electrically isolated active device regions in a silicon substrate. CONSTITUTION: A layer of silicon oxide is first formed on the silicon substrate. A mask is then formed on the oxide layer to define at least one surface region of the oxide that is not covered by the mask and a continuous strip of mask material that extends continuously around the unmasked oxide surface region. The mask is then used to etch the oxide surface region to expose an underlying substrate surface region and, thereby creating a continuous wall of oxide around the substrate surface region. The mask is then removed and oxygen ions are implanted into the silicon substrate to define a horizontal layer of oxide ions within the substrate. The wall of oxide surrounding the substrate surface region impairs the implant of oxygen ions beneath the wall such that a continuous substantially vertical wall of oxygen ions is formed in the substrate extending from the perimeter of the horizontal oxygen ion layer to the surface of the substrate. The substrate is then heat treated to cause the oxygen ions in the substrate to react with silicon to form silicon oxide that defines a silicon oxide island on all sides except the surface of the substrate, thereby forming an electrically isolated active device region.
