Latest Patents

Among Frank Herrmann's latest inventions are several patents that showcase his expertise and innovative spirit. The first patent details a method for producing a thermal infrared sensor array in a vacuum-filled wafer-level housing. This cutting-edge methodology allows for the creation of extremely compact sensor arrays composed of at least two wafers, including a cover wafer and a central wafer, featuring multiple infrared-sensitive sensor pixels on a thin slotted membrane positioned over a heat-insulating cavity.

Another notable patent focuses on the production of a high-resolution monolithic silicon micromechanical thermopile array sensor. Utilizing wafer-level packaging technology, this sensor achieves high spatial resolution with a minimal overall thickness, facilitating cost-effective production using standard CMOS processes. The inventive process involves rigidly connecting the cover wafer to the central wafer containing the sensor pixels through wafer bonding, followed by thinning out the central wafer to a specified thickness.

Additionally, Herrmann has contributed to the development of an SMD-enabled infrared thermopile sensor. This compact sensor includes miniaturized thermopile pixels integrated into a hermetically sealed housing made from a non-metallic substrate. Notably, the sensor design incorporates an aperture opening in the housing cover that focuses radiation onto the thermopile pixels, resulting in an overall housing height of less than 3 mm or even 2.5 mm.
