Abstract

The invention describes a radiation-emitting semiconductor component with a luminescent conversion element, at which the semiconductor body is placed in a recess of the base body. A cup-like area is molded inside of the recess around the semiconductor body, which contains the luminescent conversion element and coats the semiconductor body. The cup-like portion is formed as indentation inside of the recess or as annular border on the base of the recess.
