Abstract

In order to optimize the performances of YBaCuO thin films, elaborated by a two step process on SiO2/SiN4/Si substrates, we have studi&1 the effect of rapid thermal annealing (EA) conditions on low temperature (i.e. < 200°C) sputter&i layers, in the thickness range 0.3 - 1.5 m. Both the superconducting properties and the surface quality of the layers have been investigated. One of the advantages of this process is to allow the use of a very thin nitride layer (i.e. 45 A), to avoid the harmful diffusion of silicon from the wafer. This fast technique is also efficient to prevent interdiffusion between the silica and YBaCuO layers . Our first results show that an onset temperature in the 87-91K range can been obtained, with T(R.o) 60 K and 'c 500 A. Clii (at T(R.o /2) . It is also shown that these figures might be improved by repeated RTA cycles.
