Previously, it was found that yttria stabilized zirconia (YSZ) film is quite effective to stimulate crystallization of amorphous Silicon (a-Si) at low temperature. For using the YSZ effect to fabricate electron devices, e.g., TFT, on a flexible substrate and environment friendly material of cellulose nanopaper (CNP), a crystallized YSZ must be deposited without plasma and thermal damage to CNP. Earlier, we have reported that a crystallized YSZ film can be deposited on CNP without any damage using DC magnetron sputtering with Ar and O₂. In this meeting, we show that pre-sputtering condition or treatment of target surface before deposition is one of the important factors for deposition of a highly crystallized YSZ film. Films deposited with pre-sputtering at high O₂ flow rates, showed better film qualities due to stabilization of discharge conditions.
