Intel initiated construction on a 107,000 square-foot photomask manufacturing facility at its Bowers Campus in Santa Clara, California, with a formal groundbreaking ceremony attended by top executives and Santa Clara Mayor Lisa Gilmor. The new cleanroom facility will produce 6-inch × 6-inch photomasks for both DUV and EUV layers across process nodes from 32 nm down to 1.4 nm class, with primary focus on advanced process technologies—Intel 18A, 18A-P, 14A, and beyond—that require leading-edge photomasks with extremely dense patterns and advanced optical proximity correction.
Intel is one of few chipmakers worldwide that still maintains an in-house mask shop and is the only semiconductor producer to manufacture its own photomask-writing tools through its IMS Nanofabrication subsidiary. Producing masks in-house is critical for EUV because EUV tools damage masks over time despite protective pellicles, requiring rapid turnaround on new mask production. IMS's multi-beam mask writers (MBMWs) project 262,144 independently programmable electron beams simultaneously, achieving nanometer-scale placement accuracy and dramatically increasing throughput versus single e-beam tools. The Bowers Campus has been Intel's primary mask manufacturing hub since 1986.
For chipmakers and process engineers, Intel's photomask expansion signals commitment to defending leading-edge manufacturing amid reshuffling of fab capacity and geopolitical supply-chain risk. Mask production directly affects Intel's 18A/14A schedule slippage or acceleration—shortening the mask feedback loop is a competitive lever against TSMC's N2 production ramp. For Intel Foundry Services customers seeking to manufacture at these nodes, faster mask turnaround reduces engineering cycles and improves yield learning curves.
