Abstract:
1. A method for fabricating the MEMS device, comprising: depositing a first carbon film onto a substrate; lithographically patterning the first carbon film to remove a first sacrificial pre-removal portion to expose the substrate, the first sacrificial pre-removal portion corresponding to a first recess portion of a suspended thin film microstructure; depositing a second carbon film conformally onto the first carbon film, wherein a portion of the second carbon film corresponding to the first recess portion is in direct contact with the substrate at a location corresponding to the first sacrificial pre-removal portion; lithographically patterning the second carbon film to form an opening so as to expose an anchoring portion of the substrate; depositing and lithographically patterning the suspended thin film microstructure onto a stack of the first carbon film and the second carbon film; and removing the first carbon film and the second carbon film.
