Micromechanical resonator

A micromechanical resonator comprising a resonator element having a length and a width that is perpendicular to the length, wherein

• the resonator element comprises a first layer structure that comprises a base layer made of a semiconductor material,
• the length of the resonator element extends along a crystalline direction of the semiconductor material,
• the resonator element has a length-to-width aspect ratio in a range of 1.8 to 2.2.
• the resonator element is suspended to a support structure with two or more anchors, wherein each of the two or more anchors is attached to:
• a) a first location at a shorter, widthwise side of the resonator element, wherein the first location divides the width of the resonator element into a larger portion and a smaller portion such that a ratio between said smaller portion and the whole width is in a range of 0.10 to 0.28 or
• b) a second location at a longer, lengthwise side of the resonator, wherein the second location divides the length of the resonator element into a larger portion and a smaller portion such that a ratio between said smaller portion and the whole length is in a range of 0.36 to 0.50.
