TSMTaiwan Semiconductor Manufacturing Company

World's largest contract semiconductor foundry; no public quantum process design kit (PDK) exists. TSM's quantum foundry role is speculative and not confirmed. Intel's Horse Ridge cryo-CMOS chips were fabbed on Intel's own 22nm FDSOI and 10nm SuperFin processes, not at TSM.

TSM's quantum role is speculative: no public quantum PDK is offered and no confirmed quantum customer engagements. Near-term, cryo-CMOS ASICs (including Horse Ridge II) are Intel-internal-process-fabbed. Long-term, cryo-CMOS for qubit control (operating at 4K) may eventually transition to TSM advanced CMOS nodes for density if commercial market develops. Highly speculative — listed only for forward-looking supply chain completeness. Risk: no current TSM quantum revenue or confirmed program.
