Process design kits (PDKs), DFM, and OPC/mask data prep
BOTTLENECKFoundries control proprietary PDKs that lock customers to their process, and a duopoly dominates OPC/MDP software.
Foundry rulebooks and software that translate chip layouts into mask-ready data. PDKs tie customers to a foundry's process; OPC/MDP tools correct optical distortions at sub-wavelength nodes. Foundries capture value through PDK control; Synopsys and Cadence split the ~$1B+ OPC/MDP market.
Foundry-provided PDKs encoding process rules, device models, and DFM constraints; optical proximity correction (OPC) and mask data preparation (MDP) software translating layout to mask-write format.
What the evidence shows
TSMC and Samsung use PDKs as a competitive moat, creating customer lock-in.
semiconductorx.comPDKs for advanced nodes below 7nm include complex modeling for finFET variability and EUV lithography.
grokipedia.comA second portable PDK standard, OpenPDK, started last year and has not yet delivered actual PDKs.
semiwiki.comWho controls it
No independently verified market-size figure is published for this node yet.
Where it sits in the stack
Takes in: Foundry process rules, device SPICE models, design layout (GDSII)
Sends on: Mask-write-ready data; DFM-compliant layout
