PSK is a Korean equipment maker that holds the leading global share in photoresist strip, or ashing — the step that cleanly removes patterned resist after it has done its job, along with dry-cleaning systems that clear residues between process stages. Ashing is a mandatory, repeated step in every wafer flow, and PSK supplies the memory and logic heavyweights, including Samsung and SK hynix, plus global foundries. The structural read is concentration: leadership in a narrow but unavoidable niche means PSK's tools are embedded across the fab base that builds AI memory and logic, giving it durable presence within foundry capacity.

Frequently asked
What is PSK Inc.'s role in the AI supply chain?
The model reads PSK Inc. primarily as a supplier in Chips. Its largest modeled sensitivity is a shock at Silicon wafer supply (constraint β 24).
Which parts of the AI value chain is PSK Inc. exposed to?
PSK Inc. is mapped to 1 part of the AI value chain, most strongly Foundry capacity. It sits primarily in the Chips layer as a supplier.
Does PSK Inc. own an AI bottleneck?
Not in the current model — PSK Inc. is exposed to constrained parts but sits downstream of them rather than producing them.
What is PSK Inc.'s biggest AI supply-chain risk?
Its largest modeled sensitivity is a shock at Silicon wafer supply (constraint β 24). 4 nodes depend on it; pressure 61/100
Who are PSK Inc.'s closest peers by AI-chain position?
By shared chain dependencies: TOPPAN Holdings, Dai Nippon Printing, Photronics, Carl Zeiss SMT.
