Liquid crystal display device and fabrication method thereof

A liquid crystal display device comprising:

• a first substrate divided into a pixel part and first and second pad parts;
• a gate electrode and a gate line formed at the pixel part of the first substrate;
• an active pattern as an island formed over the gate electrode with a first insulation film interposed therebetween, and having a width smaller than the gate electrode;
• an ohmic-contact layer formed on source and drain regions of the active pattern on the first substrate;
• source and drain electrodes formed as islands over the gate electrode of the first substrate and electrically connected with the source and drain regions of the active pattern via the ohmic-contact layer;
• a data line formed on the pixel part of the first substrate and crossing the gate line to define a pixel region;
• a pixel electrode formed at the pixel region and electrically connected with the drain electrode;
• a second insulation film formed on the first substrate;
• and
• a second substrate attached to the first substrate in a facing manner.

A method for fabricating a two-metal stacked structure comprising:

• forming first and second conductive film on a substrate;
• forming a first photosensitive film pattern on the substrate;
• selectively removing the second conductive film by using the first photosensitive film pattern as a mask to form a second conductive film pattern;
• collapsing the first photosensitive film pattern through a baking process to form a second photosensitive film pattern covering the second conductive film pattern;
• and
• selectively removing the first conductive film by using the second photosensitive film pattern as a mask to form a first conductive film pattern having a width larger than the second conductive film pattern.
