Paper Abstract

We report a theoretical and experimental comprehensive study of the synthesis of TiN by RPLD from Ti targets in (0.2 - 50) Pa nitrogen. We used an UV XeCl* excimer laser source ((lambda) equals 308 nm, (tau) FWHM<EQ 30 ns). The deposited structures were characterized by electron microscopy, XPS and RBS. We observed a tight interval of the ambient gas pressure of (0.7 - 7) Pa within we deposited stoichiometric, polycrystalline TiN films. The theoretical analysis was performed with a numerical multifluid code using the 1D heat- conduction equation. The transit of the ablated material from target to collector was treated by a Monte-Carlo method. Finally, the thickness profile of the deposited films was predicted. The obtained results are in good accordance with experimental measurements.
