Overview
Sumitomo Heavy Industries is headquartered in Tokyo and makes a wide range of industrial machinery. In semiconductors it is known for cryopumps, which reach high vacuum by freezing gas molecules onto very cold surfaces, and for the Gifford-McMahon (GM) cryocoolers that cool them.
Its ion implanter business is run by a separate group company, Sumitomo Heavy Industries Ion Technology.
Business: Cryopumps and cryocoolers
Why it matters
- Sputtering and ion implantation need a clean high vacuum, and cryopumps provide it without oil.
- The same cryocooler technology is used in MRI magnets and research equipment.
