Abstract(in English) | We studied that the influence of SiON film composition on HIGFET characteristics. The SiON films investigated in the present study were deposited by plasma-enhanced CVD. We used the refractive index of the SiON films as indicator of film composition. We have reported, from the view point of reliability in HIGFET structure, that the gate leak current increases under a reverse gate-drain bias ^<(1)(2)>. Using the SiON film with a refractive index 1.58, we got the best HIGFET performance with no degradation mentioned above. These results are explained by thermal stability of SiON/GaAs interface, according to Spectroscopic Ellipsometry, X-ray Photoelectron Spectroscopy and Auger Electron Spectroscopy analysis. When the SiON films with a refractive indexes other than 1.58 were used, the above analyses indicate the formation of As, AsO, As_2O_3, Ga_2O_3 at the interface, which cause the degradation of HIGFET characteristics. |
