Introduction

Vit Janirek is an inventor based in Rožnov pod Radhoštěm, Czech Republic. His patent work concerns semiconductor manufacturing and methods for improving the quality of CZ silicon substrates.

Latest Patents

Janirek is associated with 1 patent, titled “Methods of Manufacturing Semiconductor Devices and Semiconductor Devices.” The invention describes a process that first anneals an unpolished CZ silicon substrate in an inert environment and then anneals it in a wet oxidation environment. The first step dissolves oxide along the inner walls of voids in the substrate, while the second helps fill those voids with semiconductor interstitials.

In some examples, the CZ silicon is grown from an ingot using a magnetic field and continuous counter-doping. The process is intended to reduce crystal-originated particle defects and oxygen concentration, while also reducing radial resistivity variation.
