Resolution Enhancement video

This is an interesting video by Asianometry about a new advancement in IC chip lithography.  But the interesting thing to me was the concept that to get better resolution they actually change the masks to distort the image but that this distortion is then automagically converted by the defects in the optical process into the correct pattern for the IC.

  He mentions the idea of serifs on typefaces being somewhat similar.  Adding those little squiggles to plain old block letters actually makes them easier to read.  A lot of people think something like Times New Roman looks old fashioned but the Times knows that it makes their copy easier to read.

I was thinking of another similar concept: predistortion for RF linear amplifiers.  Usually this is done with the DSP based rigs where the audio is processed with DSP to add artifacts which get smoothed out due to the amplifier distortion and results in a cleaner signal.   So the next step will probably be using a special NVIDIA chip :)

People are really clever !
