Latest Patents
One of Kruger's latest inventions is an ellipsometer designed for the examination of samples. This ellipsometer features a broadband light source on the emitter side and a detector on the receiver side, which captures the light beam reflected from the sample. It includes a refractive optic that generates a precisely defined measuring spot on the sample, along with an aperture on the emitter side for further definition. This invention simplifies the process of producing a defined measuring spot, enhancing the accuracy of measurements.
Another significant patent involves a method for determining characteristic values of transparent layers in the nanometer range. This method allows for the determination of layer thickness and refractive index using a spectro-ellipsometer. The invention aims to achieve accurate measurements even with a less complex ellipsometer that operates at one or a few wavelengths. By measuring ellipsometric angles and the wavelength-dependent reflection of the probe, Kruger’s method provides a reliable way to determine spectral dependencies of characteristic values.
