Patent ID: 6951824

Claim:
A method for manufacturing a micromechanical component including at least one hollow space and at least one of a functional element and a functional layer, the at least one of the functional element and the functional layer provided at least partially in the at least one hollow space, the method comprising: providing the at least one of the functional element and the functional layer with a first protective layer at least in an area that borders one of directly and indirectly on a first sacrificial layer, a material of the first protective layer being selected so that at least one of an etching process and an etching medium one of: i) does not substantially attack the first protective layer, and ii) substantially attacks the first protective layer only at a first reduced etching rate in comparison to a first etching rate of the first sacrificial layer, on a side of a second protective layer facing away from the first sacrificial layer, the at least one of the at least one etching process and the etching medium one of etching and dissolving the first sacrificial layer; forming the at least one hollow space in at least one etching step subsequently to providing the first protective layer, the first sacrificial layer temporarily occupying at least partially a space of the at least one hollow space; providing a cap layer that at least partially surrounds the at least one hollow space; and selecting a second material, the at least one of the functional element and the functional layer and at least one of the first sacrificial layer and a second sacrificial layer being substantially composed of the second material.
