Publication number: 20210188625Abstract: Aspects of the invention relate to a semiconductor chip comprising a substrate and a stack arranged on the substrate. The stack comprises one or more insulating layers and one or more metal layers. The chip comprises a sensor device arranged in a sensor area (SA) of the semiconductor chip and processing circuitry arranged in a processing area (PA) of the semiconductor chip. The chip further comprises connection circuitry configured to provide an electrical connection between the sensor device and the processing circuitry. A first seal ring structure is arranged between an outer edge (ED) of the chip and an inner area (IA) of the chip. The inner area (IA) of the chip encompasses the sensor area (SA) and the processing area (PA). A second seal ring structure is arranged between the sensor area (SA) and the processing area (PA) and configured to constrain an infiltration of contaminants from the sensor area (SA) to the processing area (PA).Type: ApplicationFiled: May 17, 2018Publication date: June 24, 2021Applicant: Sensirion AGInventors: Matthias STUDER, Robert WÜEST, Matthias MERZ, Gijs VAN STEENWIJK, Dominikus KÖLBL, Cyrill KÜMIN

Patent number: 9995700Abstract: The sensor device comprises a hotplate on a membrane. The hotplate is heated by a N-fold rotationally symmetric heater structure having N>1 heater elements of identical design. Each heater element comprises an inner section, an intermediate section and an outer section arranged in series, with the inner section having a larger electrical cross section than the outer section. This design allows to heat the hotplate to a homogeneous temperature at moderate supply voltages.Type: GrantFiled: July 13, 2015Date of Patent: June 12, 2018Assignee: Sensirion AGInventors: Cyrill Kuemin, Lukas Buergi, Nicolas Moeller
