Title: The Innovations of Olaf Schönfeld

Introduction

Olaf Schönfeld is a notable inventor based in Wuppertal, Germany. He has made significant contributions to the field of semiconductor technology, holding two patents that showcase his innovative methods in producing light-emitting components and semiconductor bodies.

Latest Patents

One of Schönfeld's latest patents is a method for producing a light-emitting component. This invention involves forming a sequence of layers, including at least one active layer, on the front face of a basic substrate made of semiconductor material. The basic substrate is then partially removed, and the sequence of layers is connected to an external substrate. The removal process utilizes wet-chemical etching, which selectively acts on the substrate material. Following this, a first metallic contact layer is applied to the sequence of layers, and a second metallic contact layer is applied to the external substrate. The connection between the two layers is achieved through eutectic bonding using heat.

Another significant patent by Schönfeld is a method for producing semiconductor bodies with a metal organic vapor phase epitaxy (MOVPE) layer sequence. This method involves forming a semiconductor body from a layer sequence with an active zone applied to a semiconductor wafer. The layer sequence is then dry etched to create at least one mesa trench, ensuring that the active zone is severed. The composite of the semiconductor wafer and the layer sequence is subsequently severed to create at least one semiconductor body with a mesa edge.
