Abstract
In a method of the present invention for fabricating a two-dimensional image detector in which a light/radiations detection element is applied, an upper electrode, a first charge blocking layer, and a semiconductor layer having photoconductivity are provided on support substrate in the stated order, and thereafter, a surface of the semiconductor layer is sprayed with ceramic particles by means of an abrasive grain jet nozzle. The abrasive grain jet nozzle repeatedly makes a high-speed reciprocating motion in an X direction at constant cycles while jetting the ceramic particles to the entirety of the surface of the semiconductor layer of the counter substrate moving in a Y direction, so that the surface of the semiconductor layer is subjected to a flattening treatment. This enables to provide a two-dimensional image detector in which a light/radiations detection element that provides effective improvement of a charge blocking effect and suppression of deterioration of reliability is applied.
