The present disclosure provides a method for the surface modification of microstructured components having a polar surface, in particular for high-pressure applications. According to the method, a microstructured component is contacted, in particular treated, with a modification reagent, wherein the surface properties of the component are modified by chemical and/or physical interaction of the component surface and of the modification reagent.

Embodiments of the present disclosure can include a method for frequency trimming a microelectromechanical resonator, the resonator comprising a substrate and a plurality of loading elements layered on a surface of the substrate, the method comprising: selecting a first loading element of the plurality of loading elements, the first loading element being layered on a surface of a region of interest of the substrate; heating the first loading element and substrate within the region of interest to a predetermined temperature using an optical energy source, causing the first loading element to diffuse into the substrate; and cooling the region of interest to form a eutectic composition layer bonding the loading element and the substrate within the region of interest.
