Latest Patents
One of Klaus Graff's latest patents is titled "Process for manufacturing a silicon semiconductor device having a reduced surface recombination velocity." This innovative process involves forming multiple semiconductor zones on the surface of a silicon wafer. It aims to reduce the surface recombination velocity of charge carriers by maintaining a temperature below 100°C while performing several steps, including cleaning the surface, drying it with a non-oxidizing gas, and applying a layer of lacquer. The lacquer contains halogen in a concentration of more than 0.1 volume %, which helps generate an electrically non-conducting layer and reduce the surface recombination velocity.
Another significant patent is "Process for reducing the surface recombination speed in silicon." This invention addresses the need for reduced surface recombination in the manufacture of silicon-based electronic devices. The process involves applying a lacquer layer to silicon wafers, effectively lowering the surface recombination velocity to below 100 cm/s. This advancement is crucial for various measurements and analytical methods used to determine the purity of silicon.
