Metal-insulator-semiconductor (M-I-S) structure has been employed for GaN HEMTs to suppress gate leakage current. In this work, various gate insulator materials including SiO2, HfO2, La2O3, HfO2/SiO2 and La2O3/SiO2 were investigated for GaN MIS-HEMT application. It is found that GaN MIS-HEMT with La2O3/SiO2 composite oxide results in better device performance and reliability as compared to other gate...
This study utilizes 355 nm ultraviolet (UV) laser' micro electroforming process with supercritical fluid to package 4G solidly mounted resonator (SMR) wafer. The diameter of drilling hole was 100–150 μm with the wafer thickness of 550 μm' and the component was packaged by the embedded circuit and through silicon via (TSV) technology. Experiment results show the aspect ratio was around 5 and the sidewall...
Room temperature fabricated aluminum-doped zinc oxide (ZnO:Al) films were deposited by radio-frequency magnetron sputtering under pure Ar ambient. By investigating and controlling the sputtering parameters, such as relative position between target and substrate, and working pressure, high quality ZnO:Al films were obtained. Even without substrate heating during deposition or post annealing process,...
