Abstract (in Japanese) (See Japanese page) 
(in English) We have theoretically analyzed the electric field distribution for multi-step and graded Field Plate (FP) AlGaN/GaN HEMTs based on an ensemble Monte Carlo 2D device simulation. The concept of multi-step FP structure was proved to be effective for improving the breakdown voltage of AlGaN/GaN HEMTs. It was demonstrated that the electric field distribution of the graded FP structure is more uniform than that of the multi-step FP structure. As a design guideline for the FP HEMT, a simple equation describing the relationship between the FP length and the SiO2 film thickness was derived for a given drain voltage.
