Title: Innovations in Silicon Production: The Contributions of Thomas Wetzel
Introduction
Thomas Wetzel, an accomplished inventor based in Haiming, Germany, has made significant strides in the field of semiconductor manufacturing. With a deep understanding of crystalline silicon production, Wetzel holds a patent that revolutionizes the method of producing silicon single crystals and semiconductor wafers.
Latest Patents
Wetzel's sole patent is titled "Method and device for the production of a silicon single crystal, silicon single crystal, and silicon semiconductor wafers with determined defect distributions." This innovative method involves pulling a silicon single crystal from a molten state utilizing the Czochralski technique and employing a rotating crucible. The process specifies a deliberate heat application to the center of the growth front, resulting in a silicon single crystal with an oxygen content ranging from 4*10 to 7.2*10, alongside a radial concentration change for boron or phosphorus of less than 5%. This technique minimizes agglomerated self-point defects while also allowing semiconductor wafers, derived from the single crystal, to contain vacancy defects as the sole type of self-point defect.
