ABSTRACTA Xe flash lamp (FL) heating technique was applied to the post deposition annealing process (PDA) for HfAlOx/SiO2 gate insulator with poly-Si or W/TiN gate electrode in a gate last based process. In the case of W/TiN/HfAlOx/SiO2, CV hysteresis with less than 10mV was achieved using the FL-PDA. However, the FL-PDA increased hysteresis width up to over 100 mV when poly-Si was used as a gate electrode. That occurred also with low temperature (700 °C) rapid thermal PDA process. The lower thermal budget achieved by the flash lamp annealing and the metal gate is effective to suppress the interfacial reaction which causes the traps responsible for the hysteresis. Charge trapping in the W/TiN/HfAlOx/SiO2 was evaluated using CV hysteresis characteristics in the MISFETs and the MIS capacitors. Electron was major trapped charge of the HfAlOx.

AbstractThis work reports on the epitaxial growth of crystalline high-k Gd2O3 on Si (111) by Molecular Beam Epitaxy (MBE) for CMOS gate application. Epitaxial Gd2O3 films of different thicknesses have been deposited on Si (111) between 650°C~750°C. Electrical characterizations reveal that the sample grown at the optimal temperature (700°C) presents an equivalent oxide thickness (EOT) of 0.73nm with a leakage current density of 3.6×10-2 A/cm2 at |Vg-VFB|=1V. Different Post deposition Annealing (PDA) treatments have been performed for the samples grown under optimal condition. The Gd2O3 films exhibit good stability and the PDA process can effectively reduce the defect density in the oxide layer, which results in higher performances of the Gd2O3/Si (111) capacitor.
