Abstract: InGaAs MOS capacitors with HfO2 and La2O3 gate dielectrics have been investigated. La2O3 capacitor was found to result in large leakage current. This can be attributed to the annealing-induced As diffusion into La2O3 layer from InGaAs substrate. This leakage current was found to be suppressed by inserting HfO2 layer between La2O3 layer and InGaAs.
