Paper Abstract

Polarization modulated spectroellipsometer was utilized to monitor, in-situ, deposition of Ag on Si substrate. The angle of incidence was determined using a Si substrate covered with native oxide. In the wavelength region of 550 nm to 700 nm, the ambiguity of the angle of incidence was within 0.2 deg. A plasma resonance peak manifested in reflectance spectrum around 350 nm increased and shifted to shorter wavelength as the deposition time increased from 1 sec to 10 sec. (Delta) (Psi) trajectory approached to a simulation curve of a continuous film as the deposition time increased to 40 sec where the film thickness was estimated to be 20 nm.
