Abstract: Dc Josephson characteristics in the bridge type weakly linked Josephson junctions using screen printed high-Tc Y(Ba)_2(Cu)_3O_<7-y> superconducting thick films are presented. Relations between averaged grain size and weakly linked total cross sectional area in the bridge junction are also presented. Fabrication techniques using granularly junction for Josephson device applications are proposed. A zero resistance critical temperature of the screen printed sample, 81K, is measured by an automatic measuring system constructed in our laboratory. The grain characteristics for various fabrication conditions are observed by a scanning electron microscopy. The current-voltage Josephson characteristics at different operating temperatures, different sintering temperatures and different cross sectional areas in the bridge are measured. The critical current dependences on the sintering temperature and total cross sectional area are expected.
