  • Abstract
    Al2O3/InGaAs interface has been studied and optimized for a 300mm compatible process. XPS analysis and electrical measurements of MOS capacitors revealed that a NH4OH treatment associated with TMA precursor pulse before the ALD deposition is efficient to remove InGaAs oxides. This yields to a good Al2O3/InGaAs interface quality with a low Dit value (~3×1012 cm-2eV-1), and passivated border traps.
