Abstract

The atomic layer deposition (ALD) of SrO was conducted on various oxide surfaces by using strontium bis(tri-isopropylcyclopentadienyl) and water at deposition temperatures of 200 and 250°C. The initial and steady growth behaviors were studied by in-situ spectroscopic ellipsometry and ex-situ X-ray photoelectron spectroscopy. For initial growth, the growth per cycle (GPC) of SrO not only depends on the concentration of hydroxyl groups but also the formation of interfacial Sr-O-Si bonds. For the steady growth, in-situ annealing was used to enhance the growth rate and multiple growth regions were identified.
