Title of Contract, Award, or Gift: Reliability Study of E-mode GaN HEMT Devices

Name of Granting or Contracting Agency/Entity: Semiconductor Research Corp

Program Title: N/A

Note:

We propose to investigate the reliability of enhancement-mode (E-mode) GaN HEMT devices with high resolution (HR) TEM/STEM and electrical characterization. In particular the recently discovered time dependent dielectric breakdown (TDDB) of forward biased gate will be studied on commercially available E-mode GaN HEMT devices. The location and nature of the breakdown percolation path will be determined by HR TEM/STEM and will be correlated with the electrical TDDB data. In-situ TEM technique will be utilized to study the time evolution of the TDDB failures.
