Episode notes
Toto Is A Semiconductor Ceramics Supplier
- Toto's advanced ceramics business supplies precision ceramic components for semiconductor fabs, not bathrooms.
- The parts include electrostatic chucks and air bearings that hold silicon wafers during etch and deposition and must tolerate extreme heat and prevent contamination.
AI Memory Demand Tightens Upstream Supply Chain
- AI-driven memory demand has tightened wafer supply and bumped fab utilization, increasing demand for precision components.
- That upstream pressure flows to niche material and component makers like Toto who make parts for wafer handling and etch tools.
Ceramics Account For Nearly Half Of Profits
- Toto's advanced ceramic division reportedly contributes about 40% of the company's operating profit.
- That makes the ceramics business financially significant even though the brand is publicly known for toilets.
