Shipping costs from the moon to anywhere on earth is probably pretty minimal, since you could do it with a catapult and a shell+parachute so the goods survive re-entry. I doubt mass would make a big difference there so much as volume. Shipping costs from earth to the moon is $10 000/KG IIRC though, which, if we assume that a processor weighs 10 grams and costs $100 means the value of the stuff you're selling is $10 000/KG, i.e. you can't make a profit on them. But, suppose you ship 50% of the processor's materials up (with a convenient 100% efficiency of raw materials usage), and you mine the other 50% locally. Which, does the moon have silicon? Yes, it has plenty. https://en.wikipedia.org/wiki/Lunar_resources#Resources https://en.wikipedia.org/wiki/Lunar_resources#Resources I suspect lunar silicon would be more expensive to process than terran silicon, primarily due to the lacking skilled labour market in the area. It would likely need to be extensively automated, and likely re-invented from the ground up around the different atmosphere (which while not breathable, is possibly still not clean enough for a cleanroom), gravity, potential power sources (metallurgical coal is a no-go, mainly because there's no easy oxygen but also because coal is quite expensive there). While it's possible that some raw materials are cheaper on the moon than elsewhere (e.g. platinum from asteroids), I doubt this is the case due to the previously mentioned potential for cheap moon-to-earth shipping.
