Introduction

Alexandra Senkova is an inventor associated with Vetrkovice u Vitkova, Czech Republic. Her work includes an invention concerning methods for manufacturing semiconductor devices and the devices produced through those methods.

Latest Patents

Senkova is credited with 1 patent, titled “Methods of Manufacturing Semiconductor Devices and Semiconductor Devices.” The patent describes a process that begins with an unpolished Czochralski (CZ) silicon substrate and subjects it to two annealing steps. The first anneal takes place in an inert environment, while the second occurs in a wet oxidation environment. Together, these steps dissolve oxide from void walls and fill the voids with semiconductor interstitials.

The disclosed approach can use CZ silicon grown in a magnetic field with continuous counter-doping. Its stated benefits include reducing crystal-originated particle defects, lowering oxygen concentration, and limiting radial resistivity variation.

Career Highlights

The patent identifies Senkova’s contribution to semiconductor substrate processing, an area where material quality can affect device manufacturing. The invention focuses on controlling defects and substrate properties through a sequence of thermal treatments.

Collaborations

Senkova is associated with Semiconductor Components Industries, LLC. The supplied information also names David Lysacek and Jan Hybl as coworkers, though it does not specify their roles in the patent.

Conclusion

Alexandra Senkova’s patent describes an annealing-based method intended to improve CZ silicon substrate characteristics for semiconductor manufacturing.
