This paper examines the morphology of silver layers deposited and annealed on laser ablated YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} films. Silver was found to dewet the YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} (001) surface on annealing in oxygen and nitrogen. This dewetting behavior may be kinetically inhibited by using either thick silver layers or short anneals and low temperatures. Silver layers 70 nm to 2.5 {mu}m thick were studied on films deposited on SrTiO{sub 3}, LaAlO{sub 3} and MgO substrates. Anneal times were varied from 6.5 min to 15 hrs at temperatures from 200 to 700{degrees}C.
