01What it rests on, and what rests on it
Sells into
- Leading-edge foundry capacity
“In the Account Sales Division, we receive and leverage next-generation technology needs shared by major semiconductor manufacturers such as those in memory, logic, and foundry businesses driving current momentum in the AI device market”
tel.com · primary source · Integrated Report 2026. Its table of major customers names Samsung Electronics and TSMC.
- High-bandwidth memory stacking yield
“For DRAM, we are meeting demand for high aspect ratio etch and highly difficult capacitor film deposition to secure the capacitance necessary for 2D scaling.”
tel.com · primary source · DRAM front-end etch and deposition, not HBM stacking.
- Advanced packaging capacity
“In the backend process, we also possess wafer probers used in wafer testing and bonding/ debonding systems that realize 3D packaging.”
tel.com · primary source · A product line (as extracted from the PDF), not a named customer.

03Ways to take part
Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not
- Work there
- It publishes its roles on its own careers page.Official careers page ↗
- Own part of it
- Its shares trade publicly as 8035 JP, bought and sold through a broker that reaches that exchange.8035 JP listing record ↗
- Buy from it
- What it does in the chain: Coaters, developers, etch. At this depth of the chain most sales are to other businesses, under contract. Its own page describes what it offers.Its own page ↗

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
