Abstract
PURPOSE:To enable removal of a reaction product by a method wherein an Si oxide film and a resist mask pattern for the control of impurity diffusion are formed on a polycrystalline Si film successively and the Si oxide film and the mask pattern are removed after impurity ions are implanted. CONSTITUTION:A polycrystalline Si film 3 is formed after an insulating film 2 is formed on a semiconductor substrate 1. Next, an Si oxide film 4 is formed on the film 3. And, an impurity diffusion resist mask 5 is laid on the film 4. Then, impurity ions are implanted into the films 4 and 3 from the top of the mask 5 for the formation of an impurity layer 6. A process follows, where the mask 5 is removed. In this process, a reaction product 7 formed in a im purity ions implanting process is left on the film 4. Next, the film 4 is eliminat ed. In this process, the product 7 can be easily removed concurrently with the film 4, therefore cleaning of the surface of the film 3 can be realized.
