Abstract:
1. An imaging system for providing selected myriad-pixel patterns on substrate surfaces requiring high-resolution exposure to light within limited depth-of-focus tolerance, using a plurality of reflective spatial light modulator (RSLM) chips each having an active micromodulator array area for beam transfer and a kerf area usable for addressing individual micromodulators characterized by: a) a light source ( b) a plural-plane multiplexed reflective spatial light modulator (RSLM) package ( c) means for mounting said plural-plane multiplexed reflective spatial light modulator package ( d) a plural-plane compensator mirror package ( e) projection scanning means ( f) means for mounting said plural-plane multiplexed mirror package ( whereby the individual pixel beamlets from all micromodulator chips in the multiplexed RSLM package are maintained within near-constant beamlet lengths to maintain depth-of-focus tolerance at the entry plane of said projection scanning means, and whereby the micromodulator chips in the multiplexed reflective SLM package are efficiently utilized for imaging to provide enhanced-throughput patterning of said substrate.
