Abstract :
The deposition of films of metals, metal oxides and metal nitrides on surfaces has attracted a great interest due to their importance in the microelectronic industry. An alternative method, which totally avoids resist technology, is to use the photodecomposition of azide complex layers. We have initiated a study about photodecomposition of new compounds [Cr(N3)L(H2O)2](NO3 )2, [Ni(N3)2L2].10H 2O, [CuN3L](NO3) (L=triethanolamine) and [Cr(N3)L´(H2O)4](NO3)2, [Cu(N3)L´(H2O)2](NO3) (L´=diethanolamine). We have selected the best wavelengths for each complex after a detailed study of UV-spectra. We can obtain thin metallic films of Ni and Cu by photodecomposition of azide complexes
