IBM Uses Deep-Ultraviolet Optical Lithography To Increase Circuit Counts
By
Researchers at IBM have discovered a way of getting more out of the current method used to make computer chips also known as deep-ultraviolet optical lithography.
The methods used by the scientists at IBM’s Almaden Research Center in San Jose, California, uses a method called deep-ultraviolet optical lithography. This is essentially the method used to etch circuits on chips. The IBM team said they were able to “print” circuits that are 29.9 nanometres wide. This is about one-third of the width of the smallest computer circuits in mass production today. One nanometre is a billionth of a metre.
