# Why should the resolution of photolithography follow the pattern described in moore's law? [closed]

"Moore's law is the observation that the number of transistors in a dense integrated circuit doubles about every two years." The law basically limits the improvement in the resolution of photolithography. Why should the resolution of photolithography follow such a pattern?

• This question does not appear to be about physics within the scope defined in the help center.
If this question can be reworded to fit the rules in the help center, please edit the question.

• Moore's "Law" was originally an observation, and then became an industry goal driven by economics and markets. To achieve the goal the semiconductor industry roadmaps highlighted what needed to be accomplished, and \$ were thrown at the various problems. So, the resolution of photolithography increased to meet the needs of the roadmap. No physics to the question in particular. – Jon Custer Oct 1 at 15:57
• I'm voting to close this question as off-topic because the question relates to engineering and economics, not physics. – The Photon Oct 1 at 16:05
• As someone who's worked in the semiconductor equipment industry, I agree with Jon's explanation. Moore's Law doesn't limit improvement in lithography, it drives it. – The Photon Oct 1 at 16:05
• @ThePhoton - yes, it became a self-fulfilling prophecy (to great success!). Source - having been through various roadmap meetings... – Jon Custer Oct 1 at 16:12
• @JonCuster, I was much more at the pointy end: A bunch of big wigs had a meeting and now your device had better work by the end of the year so EUV can go into production. (The year being 2012 or so, IIRC <wink emoji>) – The Photon Oct 1 at 16:17
