Aluminum Nitride films were grown on and Si (100) substrate by D.C. reactive magnetron sputtering at room temperature. Influence of sputter deposition time on properties of the AlN films was studied. Structural optical and electrical properties of the film were investigated. XRD measurements showed the presence of hexagonal wurtzite structure. The optical reflectance spectra of the film were taken and the band gap calculated varied from 4.35 to 5.3 eV. Finally MIS capacitors were fabricated on silicon substrates and variation of dielectric parameter with deposition time was reported.
