Abstract

Solution process or sol-gel process is the most reliable process to produce thin film compared to the other process such as chemical vapor deposition and physical vapor deposition. The process is easy and can be done in ambient temperature without the needs of any vacuum chamber and on top of that, it is cost effective. The process can be divided into two stages which are spin coating and heat treatment. The results from spin coating and heat treatment processes are expected to be the uniform thickness of thin film and the particle formation, respectively. Therefore the needs of finding suitable parameter for the spin coating process is very demanding due the suitable parameter will lead to uniform thickness of thin films. Spin speed is one of the parameter that influences the uniformity of the thin film. Heat treatment is the next process to promote the formation of catalyst particles. The heat treatment temperature is also influences the size of the particles form on the substrate. The results from this experiment are a uniform thin film and also the particle size that form is below ten nanometers.
