Wonik IPS
Korean maker of ALD/CVD deposition tools for memory and foundry chipmakers.
Wonik IPS rides the memory upcycle as a qualified but junior supplier, still standing behind Applied Materials, Lam, and Tokyo Electron when Samsung or SK hynix hit a real bottleneck.
Wonik IPS makes equipment that deposits materials onto semiconductor chips, and sells mainly to Samsung and SK hynix in South Korea. The company has proven it can do this job well enough that customers stick with it, but bigger global rivals like Applied Materials and Lam Research get called first when there's a real problem, and those rivals squeeze prices harder. The profits are real but thin (11.3% margin), and the whole business swings wildly: revenue fell nearly half between 2021 and 2023. What matters most is whether Samsung and SK hynix keep spending money on new factories and equipment, and whether Chinese competitors start taking share of that spending.
News of Chinese domestic ALD/CVD supplier qualified at CXMT or another Chinese memory maker. Would show Chinese equipment displacing Wonik IPS in a key growth market.
Samsung or SK hynix single-sources a next-gen HBM/V-NAND deposition step to Applied Materials or Lam Research. Would show dual-sourcing discipline eroding and Wonik IPS losing qualified-supplier status.

- Is Wonik IPS profitable in 2026?
- Yes. FY2025 net income rose 304.99% year over year to about KRW 84.0 billion on revenue of KRW 909.8 billion, up 21.6% (as of 2025-12-31). Q2 2026 operating margin was 11.3% (2026-06-30), positive but well below peers like Hanmi Semiconductor at 48.5%.
- Could AI replace Wonik IPS?
- No. Wonik IPS builds physical ALD, CVD and PECVD deposition equipment for chip fabs, a business AI software cannot substitute. Instead AI is a tailwind: demand for its tools is driven by Samsung and SK hynix expanding AI-memory (HBM) capacity, per an April 2026 company report.
- Who is Wonik IPS's biggest competitor?
- Applied Materials and Lam Research, per a Wonik IPS executive quoted in April 2026 who said Samsung and SK hynix call those global leaders first when facing process bottlenecks, making Wonik IPS a secondary domestic supplier rather than the primary choice.
- Who owns Wonik IPS?
- Wonik Holdings Co., Ltd. is the controlling shareholder with a stable stake of about 33.19% (16,148,572 shares) as of 2026-07-19. Other holders include Mirae Asset Global Investments at roughly 6 to 10% and Samsung Asset Management.
