    Abstract: A method for etching a target material in the presence of a structural material with improved selectivity uses a vapor phase etchant and a co-etchant. Embodiments of the method exhibit improved selectivities of from at least about 2-times to at least about 100- times compared with a similar etching process not using a co-etchant. In some embodiments, the target material comprises a metal etchable by the vapor phase etchant. Embodiments of the method are particularly useful in the manufacture of MEMS devices, for example, interferometric modulators. In some embodiments, the target material comprises a metal etchable by the vapor phase etchant, for example, molybdenum and the structural material comprises a dielectric, for example silicon dioxide.

    Abstract: This invention comprises a process for fabricating a MEMS microstructure in a sealed cavity wherein the etchant entry holes are created as a by-product of the fabrication process without an additional step to etch holes in the cap layer (20). The process involves extending the layers of sacrificial material (12, 16) past the horizontal boundaries of the cap layer (20). The cap layer (20) is supported by pillars (21) formed by a deposition in holes etched through the sacrificial layers (12,16), and the etchant entry holes are formed when the excess sacrificial material (12, 16) is etched away, leaving voids between the pillars (21) supporting the cap.
