Patent ID: 7286155

Claim:
An apparatus for two-dimensional patterning of a target substrate, the apparatus comprising: a light source configured to generate a beam of light; a one-dimensional MEMS device configured to modulate the light beam along a first linear direction so as to generate a line of light along the first linear direction with modulated pixels therein; a scanner configured to scan the modulated line of light across the target substrate; and one-dimensional imaging optics configured to focus the modulated line of light from the MEMS device onto the scanner and to project the modulated line of light from the scanner onto the target substrate, wherein the imaging optics comprises a fourier transform lens operating on the modulated line of light before the scanner, and an inverse transform lens in a parallel orientation as the fourier transform lens and operating on the modulated line of light after the scanner, a mechanism configured to translate the target substrate in a direction approximately perpendicular to a direction of scanning the modulated line of light so that the scanned modulated line of light covers a parallelogram swath on the target substrate.
