CMP Pad Conditioning Arm Service

CMP Pad Conditioning Arm Service for AMAT Reflexion & Reflexion LT (300mm), and AMAT Mirra (200mm)

Axus Technology provides repair and remanufacture services for pad conditioning arms for Applied Materials 200mm and 300mm CMP tools.  The comprehensive rebuild services include a component kit that replaces all of the basic mechanical components, including bearings, seals, and other routine replacement items.  In addition, each arm is operationally tested and inspected in order to identify any additional items that require attention.  These items, including motors, harmonic drives, and any coated or worn component parts, are identified and addressed as part of the remanufacture process.  For 300mm arms, the original OEM arm coating is typically removed and replaced with a more durable coating that is also easier to clean. 

Each pad conditioner assembly is tested, serialized, and delivered in “nearly new” condition for replacement in the CMP tool.  The repair cycle typically takes 3 weeks.
