A component for a micromechanical system has an upper side and a lower side disposed opposite the upper side and includes at least one first structural element that is arranged in a first region of the component and bounded by at least one first gap and at least one second structural element that is arranged in a second region of the component different from the first region and bounded by at least one second gap. The first region includes a first cutout in the lower side of the component, wherein a first thickness of the component in the first region is reduced in the second region with respect to a second thickness of the component. A minimal second gap width of the at least one second gap is larger than a minimal first gap width of the at least one first gap.

Micromechanical component and method for producing same

A micromechanical system with a system that can vibrate, has a seismic mass and at least two spring elements. The spring elements are respectively fastened on one side externally to the seismic mass and on the other side to fixed anchor points of the micromechanical system such that the seismic mass can vibrate in a movement direction. In order to obtain a particularly large frequency spacing between the useful mode and further vibration modes of the system, at least one further spring element is provided in the inner region of the seismic mass. The further spring element the is fastened to a further anchor point of the micromechanical system. A method builds a micromechanical system with a system that can vibrate.

Micromechanical system and method for building a micromechanical system

An exposed end of a micromechanical system having at least one beam-shaped element is connected to a further element of the micromechanical system at the other end thereof. To optimize the mechanical properties of the micromechanical system, recesses are provided in the beam-shaped element in such a way that the mass of the beam-shaped elements decreases toward the exposed end.
