MIID-1000 Malema Interconnect Interlock Device from Malema

MIID-1000 Malema Interconnect Interlock Device from Malema
Created exclusively for use in Chemical Mechanical Planarization (CMP) tools, the patented Malema Interconnect Interlock Device (MIID-1000) By-Pass Leak Detection and Prevention System, has been designed specifically to protect against liquid back-flow and internal bypass leaks. This capability is created via a manifold of pneumatically actuated valves that operate in a coordinated fashion in order to ensure that CMP-liquid supplies cannot be contaminated before use or during the actual CMP process. MIID-1000 has retrofit kits that can be installed into existing CMP tools.
