ABSTRACT

In this study, polycrystalline silicon thin film useful for the solar cells was fabricated by AIC(Aluminum Induced Crystallization) process. A diffusing barrier for this process is prepared with Al2O3. For the maximization of the grain size of the polycrystalline silicon, a selective blasting of the Al2O3 diffusing barrier was conducted before annealing treatment. The heat treatment for the activation of the amorphous-Si (a-Si) layer was carried out with Rapid Thermal Annealing (RTA) process. Crystallization of the a-Si layer was analyzed with XRD. It was confirmed that a-Si was crystallized at 500 o C and the silicon crystal is observed to be formed and the grain size of the polycrystalline silicon was observed to be 15.9 μm.
