The invention relates to microelectromechanical components, like microelectromechanical gauges used in measuring e.g. acceleration, angular acceleration, angular velocity, or other physical quantities. The microelectromechanical component, according to the invention, comprises a microelectromechanical chip part, sealed by means of a cover part, and an electronic circuit part, suitably bonded to each other. The aim of the invention is to provide an improved method of manufacturing a microelectromechanical component, and to provide a microelectromechanical component, which is applicable for use particularly in small microelectromechanical sensor solutions.
A microelectromechanical component, whereby a microelectromechanical chip part is attached on top of an electronic circuit part, wherein the microelectromechanical chip part is sealed by a cover part, and wherein the cover part has lead-in structures for bringing electric connections through the cover part.
A microelectromechanical component, whereby a microelectromechanical chip part is attached on top of an electronic circuit part, wherein the microelectromechanical chip part is sealed by a cover part, and wherein a dielectric layer is manufactured on a surface of the cover part.
A microelectromechanical component, whereby the microelectromechanical chip part is attached on top of the electronic circuit part so that the chip part is bonded to the surface of the electronic circuit part by means of the flip-chip method, wherein the microelectromechanical chip part is smaller than the electronic circuit part, wherein the microelectromechanical chip part is sealed by a cover part, and wherein the cover part has lead-in structures for bringing electric connections through the cover part.
