Si-based GaAs material substrate fabricated by medium bonding technology has low defect density
small effect on electrical property of the bonding device structure.Simulation analysis on mechanical characteristics of material is carried out.SiO2 is the best medium bonding layer for fabrication of MEMS substrate.The substrate material has high stress conversion rate
wide range
small displacement and simple fabrication process and is hydrophilic.The bond strength is strong and mechanical characteristics are good.Meanwhile
effect of different thickness of medium layer material on mechanical properties of Si-based GaAs material is researched.The more thicker the thickness of medium is
