Abstract:
1. A method of manufacturing a micromechanical component, comprising: providing a substrate; providing a first micromechanical functional layer on the substrate; structuring the first micromechanical functional layer to include a sensor structure; providing a first sealing layer on the first micromechanical functional layer after the structuring of the first micromechanical functional layer, the first sealing layer having at least a covering function and being at least partially anchored in the first micromechanical functional layer; structuring the first sealing layer; providing a second micromechanical functional layer on the first sealing layer; structuring the second micromechanical functional layer; and making the sensor structure capable of vibrating; providing a second sealing layer on the second micromechanical functional layer; wherein a maximum trench width which is sealable by the first sealing layer in a form of a plurality of plugs is determined, the plurality of plugs not extending to a trench bottom; and wherein the sensor structure is provided with a plurality of trenches, a first width of the plurality of trenches being not larger than the maximum trench width.
