Equipment, Spares & Materials from Multi-21

Chip-making equipment needs to be renewed regularly to ensure it keeps up with the latest technological advances. And, as a result, we’re able to access quality and cost-efficient second-hand legacy equipment from leading manufacturers.

We specialize in sourcing and supplying obsolete and end-of-life parts for discontinued inspection and metrology semiconductor equipment from suppliers such as Rudolph Technologies, KLA, Camtek and August Technology.

We provide a 28 day “parts loan service” that allows our clients to trouble-shoot their faulty equipment. Retained part(s) are purchased and remaining parts are returned for re-test / re-stocking at Multi-21 for a greatly reduced fee. Please inquire for further details.
