Samsung, SK hynix and Micron Explore Shared Fab Robot Charging Standard

Working-level staff from Samsung Electronics, SK hynix and Micron are considering a shared charging standard for mobile robots in semiconductor fabs. SEMI and other industry associations are also participating in the early-stage effort.

The proposed standard aims to let robots from different manufacturers use common charging equipment. Topics being narrowed down include battery specifications, charging-station communications and hardware, charger connections and battery management systems. The group is also consulting robotics and smart-factory specialists.

A possible future capability would link charging data with manufacturing execution systems, or MES, which coordinate factory production. That link could help align robot tasks and charging with production schedules; it is described as a potential integration, not a capability established by this initiative.

Older fabs have fewer automated material-handling systems, and people still move wafer containers and other materials in some facilities. Shared charging equipment could support the use of robot fleets from multiple manufacturers in those plants.

The effort has no final specification, timetable or division of responsibilities. The group is still determining which parts of the charging systems would be covered by a common standard.
