ESD Safe Materials


Various Materials

ESD Safe Ceramics overview

CoorsTek has developed electrostatic discharge-safe (ESD-safe) ceramics to protect sensitive microelectronic components from static electricity buildup. StatSafe™ materials and ArcResist™ coatings have electrical resistivities engineered to slowly dissipate accumulated electrostatic and secondary electron charges — preventing rapid discharge or arcing.

Example Applications

  • End effectors
  • Chuck components
