Inverse lithography produces features smaller than the wavelength of light, but it usually takes weeks to compute

Nvidia says it has found a way to speed up a computation-limited step in the chipmaking process so that it happens 40 times as fast as today’s standard.

Called inverse lithography, it’s a key tool that allows chipmakers to print nanometer-scale features using light with a longer wavelength than the size of those features. Inverse lithography’s use has been limited by the massive size of the needed computation.

Nvidia’s answer, cuLitho, is a set of algorithms designed for use with GPUs, turns what has been two weeks of work into an overnight job.
