Method and device for protecting micro electromechanical systems structures during dicing of a wafer
摘要:
A wafer cap protects micro electromechanical system (nullMEMSnull) structures during a dicing of a MEMS wafer to produce individual MEMS dies. A MEMS wafer is prepared having a plurality of MEMS structure sites thereon. Upon the MEMS wafer, the wafer cap is mounted to produce a laminated MEMS wafer. The wafer cap is recessed in areas corresponding to locations of the MEMS structure sites on the MEMS wafer. The capped MEMS wafer can be diced into a plurality of MEMS dies without causing damage to or contaminating the MEMS die.
