Investigation of high performance Edge Lifted Capacitors reliability for GaAs and GaN MMIC technology
ELC capacitor with Metal 1 as the bottom and Metal 2 as the contact metal layers. A SPAN layer is formed to provide mechanical support for the air bridge of the ELC. Lower R.I. nitride film exhibits the lowest leakage current and highest VBD behavior. ELC exhibits better ESD, TDDB and bHAST reliability results than MIM capacitor.
