There are founders who build startups, and then there’s Dr. David K. Lam, an industry architect who doesn’t just build companies, he builds categories. First Lam Research. Now Multibeam Corporation. Same playbook? Not even close. This isn’t about following the roadmap, it’s about inventing new physics at production speed.
Multibeam just locked in a $31 million Series B to scale the only production-grade multicolumn electron-beam lithography (MEBL) platform on the planet. You read that right, maskless, full-wafer direct-write at volume. When the rest of the industry was still busy squeezing legacy tools into next-gen problems, Dr. Lam was already holding the keys to parallel e-beam columns ripping through wafers with nanometer precision and 100x the throughput of conventional EBL. You want a game-changer? This one doesn’t even show up on the scoreboard, they had to build a new arena.
Massive congrats to Dr. David K. Lam and President Dr. Ken MacWilliams, two operators who’ve turned physics into product. Backed by strategic horsepower from Onto Innovation (shoutout Michael Plisinski), Lam Capital (Audrey Charles), UMC Capital (Kris Peng), and MediaTek Capital (Brian Hsu), this isn’t just capital, it’s signal. The industry’s paying attention, and for good reason.
Because this isn’t just a tool company. Multibeam is the only domestic supplier offering maskless patterning that scales, from 300 mm wafers to panel-level substrates, from quantum photonics to secure chip ID. First production system? Already shipped to SkyWater Technology. DoD backing? Secured. Integration with Synopsys? In place. And 46 patents deep, they’re not just ahead of the curve, they’re bending it.
What’s the play? Capital goes to scaling headcount, supercharging beam count, and pushing throughput into new territory. Multibeam isn’t trying to win the market, they’re engineering a market only they can win. Advanced packaging, chiplet integration, photonics, MEMS, quantum, this is where lithography stops being bottleneck and starts becoming competitive advantage.
So yeah, when you hear “maskless,” don’t think hobbyist. Think volume production. Think SkyWater. Think multicolumn. And remember the name: Multibeam. Because if you’re still thinking in single columns, you’re not just behind, you’re irrelevant.
