High Tc Y_1-xYb_xBa₂Cu₃O_7-y films were prepared on SrTiO₃(100) substrates by chemical vapor deposition method. Yb₁Ba₂Cu₃O_7-y films were obtained at higher oxygen partial pressure compared with Y₁Ba₂Cu₃O_7-y films at the same deposition temperature. Tc, o (R=0) decreased about 1.5K when Y was fully substituted with Yb. The c-axis lattice parameter of Y_1-xYb_xBa₂Cu₃O_7-y films also decreased as the amount of Yb(x) increased.
