And it’s hurting U.S. industries in a big way. President Joe Biden recently signed an executive order to try to help industries ranging from medical supplies to electric vehicles, that have been affected by this shortage. But will it solve the problem? If not, what does the U.S. government need to do to resolve the chip crisis? That’s the focus of our conversation today.

Hello, everyone. I’m Chitra Ragavan, and this is Techtopia. Joining me is John Neuffer. He’s President and CEO of the Washington, D.C.-based Semiconductor Industry Association. Neuffer is responsible for setting and leading the public policy agenda and serves as the primary advocate for maintaining U.S. leadership in semiconductor design, manufacturing, and research. John, welcome to Techtopia. John Neuffer: Hi, Chitra. Great to be here. Chitra Ragavan: I think we all have this vague understanding that all electronics are getting smaller and more portable, but I don’t think we have a grasp of just how small and portable the underlying semiconductor chips are. For the lay audience, can you explain in simple terms what semiconductor chips are and how they’ve evolved over the decades in their size, and scope and scale of applications and importance? John Neuffer: Well, most semiconductors are made from silicon, and silicon comes from sand, and people don’t realize it. Silicon is actually the second most abundant element in the earth’s crust, only after oxygen. Why are they called semiconductors and not just conductors, and that’s because they conduct electricity sometimes, and sometimes they don’t. In that regard, there’s kind of three types of materials. There’s materials that conduct electricity like metal, there’s materials that are insulators, they don’t conduct electricity that’s like glass, and there’s semiconductors, and they can do both. John Neuffer: Whether they can conduct or insulate is controlled by the use of electric fields, and that’s how you create your transistors, your on and off switches. That’s essentially what a semiconductor is. There’s actually very little kind of general knowledge of what these things are and really kind of how powerful they are. Chitra Ragavan: You’ve been in this industry for a long time. What’s the thing that surprised you the most when you first started learning about chips and what’s the thing that surprises you most now? John Neuffer: It’s an awesome technology. In the last 60 years, there’s just been an amazing pace of innovation. It’s probably the most innovative industry in the world. The chips, the transistors on the chips have gotten amazingly small. Chip manufacturers are now manipulating materials at atomic levels to make these transistors so small. John Neuffer: The most packed chips now, the highest-end chip has 54 billion transistors on one chip. That’s 54 billion on/off switches on one chip, and that’s basically the size of a quarter. The other thing that’s really happened is that chips have gotten amazingly cheap. If space travel had come down in price, as much as transistors have, the Apollo 11 mission, which cost $350 million in 1969 dollars, and put Neil Armstrong on the moon, well, that would have cost as much as a latte, and so that has driven computing power to just soaring heights, Chitra. Some of the world’s best computers in 1985 would take four and a half hours to process what the best chips now can process in one second, so it’s just been amazing pace of innovation. I think that’s a defining feature of the semiconductor industry. Chitra Ragavan: That’s absolutely incredible. Do you have like a favorite chip story that sort of encapsulates where we are today with this evolution? John Neuffer: Well, I don’t know if I have a favorite story, but I think it’s kind of amazing what chips have brought to our lives. Because of this innovation, because of the power of the chip and the miniaturization of the chip, we have computers as wristwatches now. We have tiny pacemakers in hearts that can communicate with patients and doctors. We have cellphones with five cameras, so it just … Chips are ubiquitous. John Neuffer: They’re in medical imaging devices, they control electric grids, they power navigation systems for our planes, they provide the guts of 5G communications. Semiconductors are really the greatest innovation of the past century. Without chips, you simply don’t have an Information Age. Without chips, we simply don’t have AI, IoT, quantum computing. Everything that’s kind of important for our future is being driven by innovation in the chip sector. Chitra Ragavan: Now, everything about the size and what you can pack into a chip has been sort of predicated or even predicted by something called Moore’s law. Can you sort of describe what Moore’s law is and whether it still holds true and why it matters in this context? John Neuffer: Yeah. Moore’s law basically postulates that … It was devised by Gordon Moore over 50 years ago, to one of the founders of Intel, and he said, “Listen, we should be able to double the number of transistors on a chip every couple of years.” And for the last 50 years, about every 10 or 15 years, there’s predictions that Moore’s law will reach physical limits and we’re just not going to be able to keep that pace up. Every time there’s these dire warnings that we won’t be able to keep the pace up, keep miniaturizing the transistors, keep driving, which has been the chief driving force for semiconductor innovation, there’s breakthroughs, and Moore’s law has marched forward. I will say though, that we are now, as an industry, really facing some physical
