Claim 15:
16. A method of transferring a geometric pattern to a surface of a substrate, the method comprising:
receiving, from a design file, the geometric pattern;
selecting, from a mask-less photolithography device having an array of light emitters, a subset of the array of light emitters corresponding to an entirety of the geometric pattern;
activating the subset corresponding to the geometric pattern,
wherein the light emitters are configured to emit at a range of different wavelengths,
wherein a first plurality of light emitters of the subset is activated to emit at a first wavelength and a second plurality of light emitters of the subset is activated simultaneously with the first plurality of light emitters to emit at a second wavelength;
providing simultaneous exposure to exposing a predetermined area of the surface of the substrate having a photoresist layer,
wherein the predetermined area of the surface of the substrate corresponds to the entirety of the geometric pattern for transferring the entirety of the geometric pattern simultaneously;
wherein providing simultaneous exposure of the predetermined area of the surface of the substrate causes a chemical reaction between the first wavelength, the second wavelength, and the photoresist layer;
deactivating the subset of the array of light emitters to stop simultaneously exposing the substrate; and
removing an unexposed portion of the photoresist layer from the substrate.
