The Next AI Breakthrough Isn't Chips — It's What They're Made Of (with Shalini Sharma, Ph.D.)
Chip Stock Investor PodcastShow Notes
Is chip materials science, not just GPUs, becoming the next AI bottleneck? In this video: what large quantitative models (LQMs) are and how they differ from LLMs, why the shift to 3D chips makes new materials critical, and how SandboxAQ plans to use its $500M CHIPS award.Shalini Sharma, Ph.D., who leads semiconductor materials innovation at SandboxAQ and previously worked at Applied Materials, joins us to explain how AI and quantum-based simulation can screen millions of candidate chemistries before anything reaches a lab.We cover SandboxAQ's business model and four CHIPS focus areas: PFAS-free chemistries, catalysts and precursors, fab backup batteries, and rare-earth-free magnets. We also discuss what faster materials R&D could mean for suppliers like Applied Materials, Entegris, Qnity, and Shin-Etsu, and for onshoring the chip supply chain.Chapters00:00 Intro: Shalini Sharma and SandboxAQ01:15 LQMs vs. LLMs explained02:20 Why materials are the hidden AI bottleneck03:55 From 2D scaling to 3D chips and the Angstrom era06:30 CFETs, compound semis, and science as a search problem09:15 Do LQMs have a scaling law?10:30 GPUs, ASICs, and where quantum computing fits12:10 Applied Materials vs. SandboxAQ culture16:45 Favorite science meme17:20 The $500M CHIPS award20:00 Supply chain risk: 90% of key magnet materials made abroad20:55 How SandboxAQ makes money22:45 Three go-to-market paths, including LQMs on Claude24:15 Customers and the four CHIPS verticals30:20 PFAS in data center cooling fluids31:50 What this means for materials suppliers33:45 A new wave of industrial startups?36:40 Applied Materials' AI tools for process recipes40:05 Wild card: best spot in Palo Alto41:45 Wrap-up— LINKS & RESOURCES —Join Semi Insider — $120/yearSemi Insider is Chip Stock Investor's paid research service: all research as it happens, the CSI 100 + quarterly outlook, dashboard tools (Compare Companies, Reverse DCF, supply-chain mapping), weekly live Q&A, portfolio moves before execution, and the private Discord.Join: https://chipstockinvestor.com/features-and-pricingFree demo: https://demo.chipstockinvestor.com/All our links & socials: https://linktr.ee/chipstockinvestorDisclaimer: For education only — not financial advice.
