    摘要: A method of fabricating a micromechanical device. Several of the micromechanical devices are fabricated 20 on a common wafer. After the devices are fabricated, the sacrificial layers are removed 22 leaving open spaces where the sacrificial layers once were. These open spaces allow for movement of the components of the micromechanical device. The devices optionally are passivated 24, which may include the application of a lubricant. After the devices have been passivated, they are tested 26 in wafer form. After testing 26, any surface treatments that are not compatible with the remainder of the processing steps are removed 28. The substrate wafer containing the completed devices receives a conformal overcoat 30. The overcoat layer is thick enough to project the micromechanical structures, but thin and light enough to prevent deforming the underlying micromechanical structures. Once the devices on the wafer are overcoated, the wafer is separated 32, and the known good devices are cleaned 34 to remove debris left by the dicing process. Once the devices are separated and cleaned, the overcoat may be removed, however, the overcoat typically is left in place to protect the device during the initial stages of the packaging process. Typically the devices are mounted 36 in the package substrate, the overcoat removed 38 from the devices, and the package containing the micromechanical device finished by sealing the package to enclose the device.

    摘要: Phosphonate surfactants are employed to passivate the surfaces of MEMS devices, such as digital micromirror devices. The surfactants are adsorbed from vapor or solution to form self-assembled monolayers at the device surface. The higher binding energy of the phosphonate end groups (as compared to carboxylate surfactants) improves the thermal stability of the resulting layer.

    摘要: A process for protecting a MEMS device used in a UV illuminated application from damage due to a photochemical activation between the UV flux and package gas constituents, formed from the out-gassing of various lubricants and passivants put in the device package to prevent sticking of the MEMS device's moving parts. This process coats the exposed surfaces of the MEMS device and package's optical window surfaces with a metal-halide film to eliminate this photochemical activation and therefore significantly extend the reliability and lifetime of the MEMS device.

    摘要: A method and apparatus for delivering a fine mist of a lubricant to a micromechanical device. A mixture 402 of a lubricant and a diluent carrier fluid is held in a supply reservoir 404. The mixture is forced through a nebulizer tip 406 to produce a fine aerosol. A particle selector 408 removes large droplets from the aerosol as the aerosol passes. The aerosol travels a distance through a delivery conduit 410 while the diluent carrier fluid evaporates from the nebulized droplets. The evaporation removes the vast majority of the diluent carrier fluid from the droplets, greatly reducing the size of the lubricant droplets. The evaporated aerosol enters a deposition chamber 412 and is deposited on a micromechanical device 414. The micromechanical devices may be lubricated in wafer form, in which case the lubricant aerosol will lubricate an entire wafer of micromechanical devices at one time. One embodiment produces an aerosol having a mean droplet size of less than 10 microns. Evaporation of the diluent carrier fluid reduces this droplet size to 10-500 nm by the time the lubricant is deposited on the micromechanical devices. The preceding abstract is submitted with the understanding that it only will be used to assist in determining, from a cursory inspection, the nature and gist of the technical disclosure as described in 37 C.F.R. §1.72(b). In no case should this abstract be used for interpreting the scope of any patent claims.
