Title: The Innovations of Piotr Filar
Introduction
Piotr Filar is a notable inventor based in Burghausen, Germany. He has made significant contributions to the field of semiconductor technology, holding three patents that showcase his expertise and innovative spirit. His work primarily focuses on methods for growing silicon single crystals and producing semiconductor wafers.
Latest Patents
One of Piotr Filar's latest patents is a method and apparatus for growing a silicon single crystal from a melt. This innovative process involves providing the melt in a crucible, imposing a horizontal magnetic field on the melt, and directing a gas between the single crystal and a heat shield to a melt free surface. The gas flow is controlled to extend over a region of the melt free surface that is substantially perpendicular to the magnetic induction. The apparatus designed for this method includes a crucible for holding the melt and a heat shield surrounding the silicon single crystal, which has a non-axisymmetric shape with respect to the crucible axis.
Another significant patent by Filar is a method for producing semiconductor wafers composed of silicon with reduced pinholes. This method involves pulling a single crystal at a seed crystal from a melt heated in a crucible. The process includes supplying heat to the center of the crucible bottom with a heating power that is increased at least once to not less than 2 kW during the growth of a cylindrical section of the single crystal, followed by slicing semiconductor wafers from the pulled single crystal.
