YBa/sub 2/Cu/sub 3/O/sub 7-x/ thick films were fabricated by the method of screen printing. A zero resistance state was achieved at 90K. The highest critical current density was about 150 A/cm/sup 2/ at 77K. Bridge type Josephson junction and dc SQUID were fabricated from thick films and operated at 77K. The induced steps produced by the ac Josephson effect were observed on the I-V curve when microwave radiation is applied to the junction. The clear periodic patterns of dc SQUID is observable at 77K. Environmental protection and the stability of thick films and devices were discussed.
