Abstract:
1. A method for fabricating an LCD device comprising: providing first and second substrates; forming an active area having a source region, a drain region, and a channel region on the first substrate and a storage line having a first region and a second region, wherein the active area and storage line are formed of a silicon layer; forming a first insulation film on the first substrate including the active area and the storage line; forming a first and second conductive films on the first insulation film; forming a gate electrode and a gate line, and forming a pixel electrode overlapping with the first region of the storage line on the first substrate by patterning the first and second conductive films, wherein the storage line is formed adjacent to the gate line and wherein the first region of the storage line forms a storage capacitor together with the overlapped pixel electrode with the first insulation film interposed therebetween; forming a pixel electrode pattern formed of the second conductive film on the pixel electrode; implanting impurity ions into the source and drain regions of the active area using the gate electrode as a mask and implanting the impurity ions into the exposed second region of the storage line using the pixel electrode pattern as a mask; forming a second insulation film on the first substrate including the active area, the gate electrode, the gate line and the pixel electrode; forming first and second contact holes exposing a portion of the source and drain regions, respectively, by removing the first and second insulation films; removing the second insulation film and the pixel electrode pattern on the pixel electrode to expose the pixel electrode, wherein the gate electrode and the gate line include the first and second conductive films and wherein the pixel electrode includes the first conductive film; forming a source electrode electrically connected to the source region through the first contact hole; and forming a drain electrode electrically connected to the drain region through the second contact hole and directly connected to a top surface of the pixel electrode.
