ABSTRACT:
Systems and techniques for lithography. In one aspect, a method includes producing a microelectronic device by modulating an intensity and a phase of the zero diffraction order of a radiation with a device including subwavelength features having a pitch dimension smaller than one wavelength of the radiation.
