摘要: The influence of post deposition annealing (PDA) temperatures on electrical characteristics of Al2O3/InSb metal-oxide-semiconductor capacitor (MOSCAP) structures is investigated. Low frequency C-V responses with strong inversion behavior in the whole range of measured frequency (100 Hz-1 MHz) are observed, indicating very short minority carrier response time in InSb. The PDA temperature of 300 degrees C and above would result in the reduction of maximum capacitance. At the PDA temperature of above 300 degrees C the C-V hysteresis, frequency dispersion and stretch out increases significantly, indicating the degradation of the MOSCAP structures. The degradation might relate to the interdiffusion between Al2O3 and InSb during thermal steps.
