Improvement of GaN Epitaxial Layer and AlGaN/GaN HEMTs by Patterned Sapphire Substrate Technology (JW1A.145)

Presenter: Hsin-Jung Lee, National Taiwan University

A microstructure was designed to reduce the dislocations in the epitaxial GaN layer and improve electrical characteristics of HEMTs by using the patterned sapphire substrates technology. AlGaN/GaN HEMTs with the maximum drain current density increased from 308 mA/mm to 469 mA/mm were achieved.
