Abstract
A method for manufacturing a micromechanical component including a substrate and including a cap, which is connected to the substrate and, together with the substrate, encloses a first cavity, a first pressure prevailing and a first gas mixture having a first chemical composition being enclosed in the first cavity. An access opening connecting the first cavity to surroundings of the micromechanical component is formed in the substrate or in the cap. The first pressure and/or the first chemical composition is adjusted in the first cavity. The access opening is sealed by introducing energy or heat via laser into an absorbing part of the substrate or the cap. During the step for forming the access opening, a first access opening section is formed generally perpendicularly to a surface of the substrate or the cap, and a second access opening section is formed generally perpendicularly to and in parallel to the surface.
