发明名称 METHOD OF PHOTOLITHOGRAPHIC PATTERNING
摘要 A method of photolithographic patterning mainly includes: converting a first photolithographic pattern by a digital transformation in a first magnification to a second photolithographic pattern; producing a first optical reticle corresponding to the second photolithographic pattern by an initial lithography in a 1-to-1 image transfer; fabricating a second optical reticle on a transparent substrate by a first photolithography in a first demagnification corresponding to the first optical reticle; and fabricating a microscopic pattern of same dimension as the first photolithographic pattern on a wafer substrate by a second demagnification using the second optical reticle. The multiplication of the first magnification by the first demagnification by the second demagnification equals one. The present invention implements fine patterning on a wafer substrate so as to improve efficiency of photolithographic application.
