Title: Uwe Sahr: Innovator in Semiconductor Technology
Introduction
Uwe Sahr is a notable inventor based in Nuremberg, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on methods and devices for producing monocrystalline and polycrystalline materials, which are essential in various electronic applications.
Latest Patents
One of Uwe Sahr's latest patents is a method for producing a monocrystalline or polycrystalline semiconductor material. In this innovative method, semiconductor raw material is introduced into a melting crucible and directionally solidified using a vertical gradient freeze method. The molten material trickles downward, allowing the raw material that has not yet melted to gradually slump in the melting crucible. To enhance efficiency, the semiconductor raw material is replenished from above onto a zone that has not completely melted, compensating for shrinkage and raising the filling level. Additionally, the replenished raw material is heated to a temperature below its melting point before being introduced into the crucible, minimizing thermal impact on the system.
Another significant patent involves a device for making monocrystalline or multicrystalline materials, particularly multicrystalline silicon. This device utilizes a crucible with a rectangular or square cross-section and features a flat heating device that generates an inhomogeneous temperature profile. This profile corresponds to the temperature gradient formed in the center of the crucible, with heat output decreasing from the top to the bottom. The design includes parallel heating webs that extend in a meandering course, with varying heat outputs to prevent local overheating in corner areas of the crucible.
