Patent ID: 7301155

Claim:
A method for producing a radiation detector provided in a substrate with a detection layer which is sensitive to radiation, comprising the steps of: forming said detection layer by a polycrystal film comprising either one of CdTe (cadmium telluride), ZnTe (zinc telluride) and CdZnTe (cadmium zinc telluride) or a laminate film of polycrystal including at least one thereof, and doping said detection layer with Cl, wherein said detection layer is formed by vapor deposition or sublimation while using as a source, a mixture of a first material including at least one of CdTe (cadmium telluride), ZnTe (zinc telluride) and CdZnTe (cadmium zinc telluride) and a second material including at least one of CdCl 2 (cadmium chloride) or ZnCl 2 (zinc chloride).
