WebAbstract: The quality factor (Q) of inductors on silicon (Si) is limited by the series resistance of the metal at low frequency and by the substrate resistivity at high frequency. Oxide is generally used to isolate the useful signal of the inductor from the lossy substrate. However, stoichiometric silica (SiO2) is processed at a high temperature, which eliminates the … WebMay 6, 2015 · In order to lower the crystallization temperature of amorphous silicon (a-Si) below the intrinsic ...
