Classification: CPC G | IPC G

Claim 0:
1. A digital lithography system comprising:
a first spatial light modulator pixel configured to direct a first light beam onto a substrate during a digital lithography process;
a second spatial light modulator pixel configured to direct a second light beam onto the substrate during the digital lithography process;
a light source configured to generate the first light beam, wherein the first light beam comprises a plurality of components comprising:
a first component having a first wavelength that generates a first phase shift that is greater than a preselected phase shift; and
a second component having a second wavelength that generates a second phase shift that is less than the preselected phase shift; and

a controller configured to control intensities of the plurality of components to generate an effect on the substrate that approximates the preselected phase shift.
