Title: The Innovations of Rene Stein

Introduction

Rene Stein is a prominent inventor based in Roettenbach, Germany. He has made significant contributions to the field of materials science, particularly in the growth of silicon carbide (SiC) single crystals. With a total of 12 patents to his name, Stein's work has advanced the understanding and application of SiC in various industries.

Latest Patents

Among his latest patents, Stein has developed a method for the sublimation growth of an SiC single crystal. This method involves heating under growth pressure, where a crucible holding a stock of solid SiC and an SiC seed crystal is evacuated during a starting phase. The crucible is then filled with an inert gas until a growth pressure is reached. The process includes an initial heating to an intermediate temperature, followed by a controlled heat-up phase to a growth temperature at a rate of no more than 20°C/min. This innovative approach allows for controlled seeding on the SiC seed crystal even during the heat-up phase.

Another notable patent is a device featuring a foil-lined crucible for the sublimation growth of an SiC single crystal. This device includes a crucible with a storage area for solid SiC and a crystal area where the SiC single crystal grows. The crucible is lined with a foil made from materials such as tantalum, tungsten, or molybdenum, which prevents reactions between the aggressive components of the SiC gas phase and the crucible wall.
