Abstract: Si films were deposited at low temperatures on glass substrates covered with poly-yttria-stabilized zirconia (YSZ) layers. We investigated the dependences of crystallization on the Y content and cleaning solution for the YSZ layers. Transmission electron microscopy showed that some regions of the Si film deposited at 430 °C were directly crystallized on a YSZ layer without an amorphous region, where Si lattice fringes were tightly connected to YSZ lattice fringes. The crystallization of Si films on YSZ layers occurred at deposition temperatures lower than that on glass substrates by more than 100 °C. Zr, Y, and F concentrations in the Si film were negligible, except the Zr concentration near the interface. The discussion on the crystallization mechanism gave the following suggestions on the method of obtaining a high crystalline fraction. The YSZ layer should be chemically cleaned using a solution containing HF before Si film deposition, and the content ratio Y/(Zr+Y) of YSZ should be ≳ 0.2.
