Electron Beam Induced Decomposition of Palladium Acetate

  • T.J. Stark (a1), T.M. Mayer (a2) and P.E. Russell (a3)


A focused electron beam has been used to selectively decompose sub micron thick films of palladium acetate, Pd(OOCCH3)2, resulting in the formation of <0.1μm wide Pd rich features. Resistivity of the palladium acetate film decreased when exposed to doses above 500μC/cm2. Annealing to 160°C further reduces the resistivity of the exposed areas to as low as 100μΔcm. XPS analysis of the exposed areas indicate that the Pd is reduced to a metallic state and that the ratio of C and 0 to Pd drops to 1.5 and 0.6, respectively, after exposure. Residual gas analysis during exposure indicates that CO2 and CH3 are the primary volatile products of the decomposition.
