A MEMS tribogauge was used for on-chip and in-situ characterization of nano-tribological phenomena (stiction, friction, and wear). The measurements were made on the sidewall surfaces on the tribogauge at the third structural polysilicon layer in the

A chemisorbed fluorocarbon self-assembled monolayer (FSAM) layer on MEMS surfaces can greatly improve MEMS device reliability by reducing the in-use stiction force. In this work, a MEMS tribogauge that measures stiction force between two interacting
