Singapore partner delivers 600 ceramic AM lift pin sets to a chip foundry
Singapore-based Creatz3D has supplied 600 sets of alumina lift pins, made by ceramic additive manufacturing, to a leading global semiconductor foundry. The parts passed full production qualification for chemical vapor deposition chambers, where they hold and position silicon wafers under high temperature, plasma and vacuum. According to the companies, the full cycle from printing to post-processing took six weeks, compared with months through conventional sourcing, which helps the foundry reduce overseas supply dependence. The parts use top-down stereolithography from 3DCERAM SINTO, which the company says avoids peeling forces and needs no supports. The case shows how ceramic AM is moving from prototypes into qualified production, a step that remains the main barrier for the technology in semiconductor manufacturing. Lithoz reports a similar partner-based model.
