Ultrathin-barrier normally off AlN/GaN/AlGaN double-heterostructure field-effect transistors using an in situ SiN cap layer have been fabricated on 100-mm Si substrates for the first time. The high 2DEG density in combination with an extremely thin barrier layer leads to enhancement-mode devices with state-of-the-art combination of specific ON-resistance that is as low as 1.25 m Omega . cm(2) and breakdown voltage of 580 V at V-GS = 0 V. Despite the 2-mu m gate length used, the transconductance peaks above 300 mS/mm. Furthermore, pulsed measurements show that the devices are dispersion free up to high drain voltage V-DS = 50 V. More than 200 devices have been characterized in order to confirm the reproducibility of the results.
