Wonik IPS Co., Ltd. — AI supply-chain exposure

Wonik IPS builds deposition equipment — the CVD and ALD tools that lay down the ultra-thin films at the heart of a chip — plus thermal-processing systems for both semiconductor and display fabs. It is one of Korea's core domestic tool suppliers, selling into Samsung and SK hynix as those memory makers expand capacity.

That gives it a direct DRAM exposure: when Korean memory makers add lines for the DRAM that surrounds AI accelerators, deposition tools are among the first equipment they order. Its structural position is as a localized supplier to a concentrated customer base — leveraged to the memory cycle, but dependent on a handful of buyers, which caps how central the model can place it in the chain.
