  • How Closed Source Intellectual Property Contributes to the Chip Shortage

    Luke informed me that the reason at the heart of the legacy chip shortage was that TSMC decommissioned and discarded their legacy lithography machines; today’s most legacy nodes have a ~250nm transistor size. TSMC was one of the last — if not the last — foundry maintaining these legacy ASML lithography machines and in early 2020 TSMC decided to decommission and throw out these machines central to many of the chips used in everyday components for products like cars, medical devices and school buses because it was unprofitable for them to maintain it. Stated another way, this part of the multi-year global microchip shortage — which according to yesterdays WSJ is still ongoing — the whole shortage started because TSMC decided to throw away their older ASML lithography machines at an inopportune time for the rest of the chip and component industry.
