The Substrate startup has been doing the rounds in the news lately, thanks to its proposition of making chips using particle accelerators and X-rays instead of conventional EUV lithography, claiming it can eventually have angstrom-sized features at only $10,000 per wafer—in U.S. fabs, no less. Those are bold claims, and an article by Fox Chapel Research (FCR) is seriously questioning whether they pay off.
The write-up is the first of two parts, and takes aim at not just the seemingly outlandish technological claims, but also at the track record of the venture's founders, as well as the overall messaging on Substrate's website. The start-up is backed by various investment funds, namely but not only Founders Fund, of whom Peter Thiel is part of.
