Latest Patents
One of Hummel's latest patents is a method for manufacturing an integrated pressure sensor. This invention features a differential pressure sensor that includes a membrane positioned over a cavity on a semiconductor substrate. A lid layer is placed on the top side of the device, which has an access opening to the membrane. Additionally, a channel extends laterally from the cavity and intersects with a bore, which is created by laser drilling from the substrate's bottom side, allowing access to the membrane's bottom side.
Another significant patent is a method and device for calibrating sensors. This innovation allows for the calibration of sensors arranged on semiconductor chips while they are still assembled on a semiconductor wafer. By exposing the wafer to a calibration fluid containing a known amount of the substance to be measured, the sensors can be calibrated at an early stage, enhancing efficiency. The calibration fluid is introduced between the wafer and a lid, enabling the testing and calibration of numerous sensors quickly.
