Abstract(in English)	High-quality Bi_2Sr_2CaCu_2O_<8+δ>(Bi-2212) single crystals were grown by a self-flux method without mixing and grinding of reageht starting powders, to simplify the growth process of the crystals. We obtained high-quality single crystals with zero-resistance transition temperature, T_≈89K, with this techniques. We also developed a new fabrication process of stacked intrinsic Josephson junctions. For the fabrication of the self-planarized stacks, the Bi-2212 around the stack was modified to the insulator by soaking into the solution of dilute (≤ 0.2%) hydrochloric acid. The number of intrinsic junctions in the stack was well controlled by the solution concentration.
