Applied Materials

Applied Materials is the semiconductor industry's invisible champion — it manufactures the deposition, etching, and inspection equipment that every chipmaker on earth (TSMC, Samsung, Intel, NVIDIA) uses to fabricate its chips. Without Applied Materials' CVD chambers and CMP tools, there are no chips; every sub-3nm node currently in production relies on its precision manufacturing systems. With $28B in annual revenue and a $170B market cap, Applied Materials captures a tax on every technological advancement in the industry. The company has 24,000+ patents and spends $3B+ on R&D annually, maintaining its position 2-3 technology nodes ahead of customer requirements and cementing what Warren Buffett would call a wide moat.
