Programmable mask and method of fabricating biomolecule array using the same

A programmable mask, comprising:

• an upper substrate;
• a lower substrate;
• a liquid crystal (LC) panel positioned between the upper substrate and the lower substrate, which has no spacer and a cell gap of the LC panel is maintained by a LC panel seal formed at a periphery of the LC panel;
• and
• a parallel light exposure device, comprising:
• a light source for emitting UV-light having a predetermined wavelength;
• a reflecting mirror positioned at one side of the light source to reflect the UV-light to another side of the light source along a light path;
• a first reflector positioned within the light path and configured to reflect the UV-light received from the light source;
• at least one intermediate reflector positioned within the light path and configured to reflect the UV-light received from the first reflector;
• and
• a second reflector positioned within the light path and configured to reflect the UV-light received from the intermediate reflector to the upper substrate, wherein predetermined spaces between the first, the second and the intermediate reflectors are configured to eliminate non-parallel light.
