Latest Patents

Johannes's latest inventions include a "Contamination Monitor for Measuring a Degree of Contamination." This innovative device allows for accurate measurement of contamination in a charged particle beam system. The monitor features a carrier with an aperture for transmitting a charged particle beam, and a membrane covering the aperture. The contamination layer’s thickness is determined by measuring the decrease in transmission through the membrane as contamination increases, with enhanced accuracy achieved through selecting a central portion of the particle beam.

Another significant patent is an "Improved Method of Manufacturing a Semiconductor Device of the 'Semiconductor on Insulator' Type." This method involves creating grooves with a predetermined depth on the major surface of a monocrystalline semiconductor body. The surface is treated with a polishing-resistant material and then coated with a chemomechanically polishable material. The process culminates in obtaining mutually insulated 'semiconductor on insulator' regions, with precise thickness matching the depth of the grooves.
