WebJul 2, 2012 · Optical lithography – the technology of patterning – enables intricate circuits to be created in wafers at dimensions smaller than the light wavelength used in the process. Optical lithography is relying more on resolution enhancement techniques (RETs), since their implementation does not require significant changes in fabrication infrastructure.
