Abstract :
A 240-nm-period grating has been fabricated in photoresist on semiconductor material by doubling of the phase-mask grating period. A standard mask aligner retrofitted with a UV laser was used for lithography. The phase mask was optimized via numerical simulation of the distribution of optical power in the photoresist.<>
