Title: **Joachim Geissler: Innovator in Semiconductor Manufacturing**

Introduction

Joachim Geissler is a notable inventor based in Stammham, Germany, recognized for his contributions to semiconductor material processing. With three patents to his name, Geissler has made significant advancements in the manufacturing and processing of silicon-based materials, which are critical in various technological applications.

Latest Patents

Geissler's latest patents showcase innovative techniques in semiconductor production. One of his patents describes a novel **process for producing rods or blocks of semiconductor material**. This method involves processing a molten phase of semiconductor material with a solid phase that has a free surface opposite to it. During crystallization, energy is radiated into this surface, and granular material is added, which melts and allows material to grow on the solid phase according to the growth rate. One of the key advantages of this process is that it eliminates the need for melting vessels and employs granular materials, resulting in a favorable energy balance due to the minimal amounts of melt.

Another significant patent is for an **apparatus and process for the manufacture of shaped bodies from silicon**. In this method, silicon grains are initially melted on their surfaces to bond with neighboring grains, forming a porous compound shaped body. This body can then be fully melted in a subsequent step. The patent also includes a design for an apparatus that utilizes an electron beam to provide energy for this initial melting process.
