Machines that build machines. It’s a curious paradox. Whenever you consider something that builds itself, physically, it could conjure thoughts of an infinity loop or an M.C. Escher painting. The never-ending loop of technology. The extreme ultraviolet (EUV) lithography machine, a marvel of modern engineering, etches patterns onto silicon wafers with unparalleled precision, giving birth to the microchips that power our world. A machine so advanced, so intricate, that it holds the power to create the very building blocks of our digital age. It gives birth to the state of the art in semiconductors. Indeed, the future pulled forward to today. As we marvel at the bleeding edge of technology, we often overlook the humble components that make it all possible. Inside every EUV lithography machine, a symphony of legacy technologies plays out, from power management diodes to analog circuits. These unsung heroes, though less glamorous than their cutting-edge counterparts, are the backbone of innovation. In the wake of the COVID-19 pandemic, the world has witnessed the fragility of global semiconductor supply chains. Black swan events have exposed the dangers of over-reliance on a single source, leading to shortages that ripple across industries. It is a stark reminder that the latest and greatest cannot exist without the tried and true. As we navigate this era of rapid technological advancement, let us not forget the importance of balance. The yin and yang of old and new, of leading and lagging-edge, are forever intertwined in the dance of progress. The lead guitar and vocals may provide the memorable moments in your favorite songs, but have you ever heard a song without the drums? Modern architecture can inspire and awe, but ever tried to build a house without a concrete foundation?  Trips to the zoo to visit the tigers provide moments of wonder; what would happen if the protective glass was removed? Remember that next time you marvel at the latest gadget or gizmo. Take a moment to appreciate the unassuming components that make it all possible. For in the grand scheme of innovation, every piece of the puzzle matters, no matter how small, outdated, or seemingly invisible.   How does Microchip Technology provide the critical components for producing Microchip Technology?   Links from the episode:     Guests:  Leon Gross
