Patent ID: 7816163

Claim:
A method of producing a radiation-emitting semiconductor body with a vertical emission direction, the method comprising: forming a semiconductor body including an active layer and a current-conducting layer positioned between a first cladding layer and a second cladding layer, a. the first cladding layer having a first conduction type, b. the current-conducting layer having a current blocking region of a second conduction type and a current-permeable region of the first conduction type; and c. the second cladding layer having the first conduction type; and forming a laser resonator containing at least a portion of the semiconductor body to produce the radiation-emitting semiconductor body forming the current-conducting layer having a second conduction type throughout the current-conducting layer, the current-conducting layer being formed over the first cladding layer in the vertical emission direction; forming the second cladding layer having the first conduction type throughout the second cladding layer, the second cladding layer being formed over the current-conducting layer in the vertical emission direction; applying a dopant source including a dopant of the first conduction type to the second cladding layer and diffusing the dopant into the current-conducting layer to form the current-permeable region by reversing the conduction type within a portion of the current-conducting layer, forming a vertical current path in the semiconductor body through the first cladding layer, the current-permeable region of the current-conducting layer and the second cladding layer.
