Paper Abstract

Tin oxide thin films based chemical sensors have been developed by means of laser induced chemical vapor deposition (L-CVD) and pulsed laser deposition (PLD) methods. The chemical composition of sensors was studied by XPS. By these two methods the tin oxide films were deposited at identical chemical chips and the sensitivity to hydrogen was measured and compared. An improvement of the sensitivity by using noble metal catalysts was observed. In addition, the possibility of detection Co, CH4, SO2, NO2 and N2O gasses on the films deposited by L-CVD technique and to alcohol vapor on the films deposed by PLD was studied.
