Describe the diffused junction method of forming a semiconductor.
What will be an ideal response?
The diffused junction method is the method most in use today. A mask with openings is placed on a thin section of N- or P-type semiconductor material called a wafer. The wafer is then placed in an oven and exposed to an impurity in a gaseous state. At an extremely high temperature, the impure atoms penetrate or diffuse through the exposed surfaces of the wafer. The depth of diffusion is controlled by the length of the exposure and the temperature.
