Preserving Moore’s Law Pushes Lithography to its Limits
The race is on to develop the next technology that will enable manufacturers to continue scaling down their chip sizes. Will optics provide the answer everyone is looking for? The brisk march of optical lithography has set the pace for the shrinking size of semiconductor devices and integrated circuits (ICs) that we see today. Optical lithography – the technology of patterning – enables intricate circuits to be created in wafers at dimensions smaller than the light wavelengt...
