PiezoMEMS processing

Material Stack
Silicon substrate with an optional thermal oxide layer followed by the piezo electric layer of AlScN with a top molybdenum electrode. 8″ wafer

  • Single electrode layer stack
  • Dual Electrode layer stack
PiezoMEMS Structures Fabrication
Piezoelectric MEMS process that combines surface and bulk micromachining to create free standing structures such as piezoelectric cantilevers or membranes for different applications. This process is on 4″ wafer (SOI Substrate) and the piezo layer can be AlN or ScAlN

Piezoelectric material properties: d33 in the range of 5 to 6 pC/N
Device properties are design dependent
