Abstract— Tin oxide is one of the most explored thin film materials for gas sensing applications. Sensing properties depend on film’s surface morphology which is tuned by either deposition parameters or by annealing considerations. This work explores the importance of annealing time to get optimum sensing response for tin oxide film. Samples annealed for 1 -5 hours were examined for electrical resistance, surface morphology and gas sensing behavior (10 ppm ammonia). The optimized annealing time is found to be 3 hours at 350°C based on the sensor response and stability over a period of 15 days.
