These small devices that manipulate the flow of electricity run everything from our PCs and smartphones to our cars to manufacturing. The semiconductor industry is at an inflection point of renewed growth, powering new movements like generative AI and electric vehicles. The Chip Stock Investor Podcast explores how semiconductors work, and especially the business of chips. Follow Nicholas and Kasey to learn how chip technology has become the engine of the world, and how to invest in its growth.","last_synced_at":"2026-07-01T06:19:34.009916+00:00","page_url":"https://stenobird.com/podcast/chip-stock-investor-podcast-6441813"},"episode":{"title":"AI Data Center Supply Chains & Indium Phosphide: A Look at Oxford Instruments","slug":"ai-data-center-supply-chains-indium-phosphide-a-look-at-oxford-instruments","published_at":"2026-06-25T14:00:00+00:00","page_url":"https://stenobird.com/podcast/chip-stock-investor-podcast-6441813/ai-data-center-supply-chains-indium-phosphide-a-look-at-oxford-instruments","show_page_url":"https://stenobird.com/podcast/chip-stock-investor-podcast-6441813","url":"https://podcasters.spotify.com/pod/show/chipstockinvestor/episodes/AI-Data-Center-Supply-Chains--Indium-Phosphide-A-Look-at-Oxford-Instruments-e3l881n","audio_url":"https://anchor.fm/s/e2cacf78/podcast/play/121953783/https%3A%2F%2Fd3ctxlq1ktw2nl.cloudfront.net%2Fstaging%2F2026-5-24%2F426777161-44100-2-4f1c1ec236a36.mp3","summary":"In this episode, CSI is cutting through the social media noise to bring you a vintage Chip Stock Investor breakdown of the semiconductor supply chain. Today, we are putting the spotlight on Oxford Instruments, a small-cap UK company that might be a critical bottleneck in the AI data center networking boom. We explore how the industry is scaling up production for compound semiconductors and specifically look at Coherent's breakthrough with six-inch indium phosphide (InP) wafers. From there, we map out the players making this transition possible and detail why Oxford Instruments' plasma deposition and etch systems are moving out of the R&D lab and onto the commercial manufacturing floor. Episode Chapters & Key Takeaways: The Indium Phosphide Breakthrough: The industry has long been stuck at two- to four-inch wafers due to manufacturing defects, but Coherent has successfully transitioned to six-inch InP wafers. Mapping the Supply Chain: A breakdown of the companies involved in this ecosystem, including Sumitomo Electric for substrates, KLA Corp and Onto Innovation for inspection, and Applied Materials for deposition. Oxford Instruments' Critical Role: Oxford Instruments supplies the plasma deposition and etch technology used by Coherent to create features like laser sources and waveguides. A Shift to Commercial Scale: Historically an R&D business spun out of Oxford University, the company is now seeing its advanced technologies group transition into early-stage commercial production. Strategic Divestitures: Oxford Instruments recently sold its quantum computing and cryogenics segment to Quantum Design to focus heavily on AI data centers and compound semiconductors. Financials & Valuation: Despite recent headwinds like tariffs and US R&D funding delays,…","meta_description":"In this episode, CSI is cutting through the social media noise to bring you a vintage Chip Stock Investor breakdown of the semiconductor supply chain.
