ABSTRACT:
A method of diffusing mercury into a crystalline compound semiconductor film including mercury includes forming an amalgam on a region of the semiconductor film into which mercury is to be diffused, forminq a protective film on the amalgam, and annealing, whereby mercury from the amalgam diffuses into the semiconductor film and the protective film prevents the mercury from escaping. Therefore, a complicated temperature profile is not required and the mercury diffusion is carried out without sealing the semiconductor film in a quartz tube. As a result, the instruments and materials used in the diffusion process are easily handled and the diffusion of mercury into a large-sized semiconductor film is possible.
