Abstract:
1. A method for manufacturing a radiation detector using gas amplification, comprising the steps of: forming a first electrode layer on a first surface of an insulating member and forming a second electrode layer on a second surface of said insulating member opposite to said second surface thereof; conducting a first treatment including resist coating, exposing, developing and etching for said first electrode layer to form a plurality of openings for processing at said first electrode layer; irradiating an energy beam onto said insulating member via said plurality of openings for processing formed at said first electrode layer or conducting a second treatment including resist coating, exposing and developing when said insulating member is a photosensitive insulating member to form through holes at said insulating member in a thickness direction of said insulating member; conducting via-fill plating into said through holes to form metallic plating layers so as to embed said through holes; conducting said first treatment for said first electrode layer to form a plurality of circular openings such that said metallic plating members are disposed at centers of said circular openings, respectively, and to form a first electrode pattern while forming a second electrode pattern made of convex portions of said metallic plating layers and said second electrode layer; and forming and reflowing a first solder material on said first electrode pattern such that edges of said first electrode pattern exposing to said openings are shaped in respective continuous first curved surfaces by covering said edges thereof with said first solder material.
