Patent number: 10035696Abstract: Measures are provided, by which mechanical stresses within the diaphragm structure of a MEMS component may be intentionally dissipated, and which additionally enable the implementation of diaphragm elements having a large diaphragm area in comparison to the chip area. The diaphragm element is formed in the layer structure of the MEMS component. It spans an opening in the layer structure and is attached via a spring structure to the layer structure. The spring structure includes at least one first spring component, which is oriented essentially in parallel to the diaphragm element and is formed in a layer plane below the diaphragm element. Furthermore, the spring structure includes at least one second spring component, which is oriented essentially perpendicularly to the diaphragm element. The spring structure is designed in such a way that the area of the diaphragm element is greater than the area of the opening which it spans.Type: GrantFiled: July 19, 2016Date of Patent: July 31, 2018Assignee: ROBERT BOSCH GMBHInventors: Fabian Purkl, Michael Stumber, Ricardo Ehrenpfordt, Rolf Scheben, Benedikt Stein, Christoph Schelling

Patent number: 9936298Abstract: For a MEMS component, in the layer structure of which at least one sound-pressure-sensitive diaphragm element is formed, which spans an opening or cavity in the layer structure and the deflections of which are detected with the aid of at least one piezosensitive circuit element in the attachment area of the diaphragm element, design measures are provided, by which the stress distribution over the diaphragm surface may be influenced intentionally in the event of deflection of the diaphragm element. In particular, measures are provided, by which the mechanical stresses are intentionally introduced into predefined areas of the diaphragm element, to thus amplify the measuring signal. For this purpose, the diaphragm element includes at least one designated bending area, which is defined by the structuring of the diaphragm element and is more strongly deformed in the event of sound action than the adjoining diaphragm sections.Type: GrantFiled: July 15, 2016Date of Patent: April 3, 2018Assignee: ROBERT BOSCH GMBHInventors: Thomas Buck, Fabian Purkl, Michael Stumber, Ricardo Ehrenpfordt, Rolf Scheben, Benedikt Stein, Christoph Schelling
