We report the successful fabrication of three-dimensional (3-D) intrinsic Josephson junctions (IJJs) using c-axis YBa_2Cu_3O_<7-y>. (YBCO) thin films of 500-800 nm thickness. The stacks of IJJs were fabricated by the lateral focused-ion-beam (FIB) etching method. The width depending on the required junction size and the full depth of film thickness were patterned in a micro area from the normal direction etching. By tilting the sample stage to 90°, two grooves of the bridge were etched from the lateral direction in accordance with the required junction size. The junction did not show any degradation of the critical current density (J_c) down to an in-plane area of 0.5 μm^2.
