Thin Bi₂Sr₂CaCu₂O_8+δ (Bi-2212) single crystals with the typical thicknesses of 20-200 nm are prepared with mechanical exfoliation, which can be firmly attached to a substrate by van der Waals and/or capillary force instead of using any glue. The thin Bi-2212 single crystals are interesting for superconduct- ing device fabrication and applications as well as the study of low-dimension superconductivity. A stack of intrinsic Josephson junctions including eight junctions is demonstrated.
