We discuss selective preferred orientation control of YBa 2Cu3O7-δ films on a substrate. c-Axis oriented YBa2Cu3O7-δ films grow on the region without buffer layer. On the other hand a-axis oriented YBa 2Cu3O7-δ films grow on the region with the buffer layer in spite of the same growth temperature and oxygen pressure. Crystalline orientation, surface morphology and transport properties along the b-axis of the a-axis oriented films will be also discussed.
