摘要： Device and method for an antireflective coating to improve image quality in an image display system. A preferred embodiment comprises a first high refractive index layer overlying a reflective surface of an integrated circuit, a first low refractive index layer overlying the first high refractive index layer, a second high refractive index layer overlying the first low refractive index layer, and a second low refractive index layer overlying the second high refractive index layer. The alternating layers of high refractive index material and low refractive index material form an optical trap, allowing light to readily pass through in one direction, but not so easily in a reverse direction. The dual alternating layer topology improves the antireflective properties of the antireflective layer and permits a wide range of adjustments for manipulating reflectivity and color point.

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： 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 micromechanical device having a deflectable member which contacts a stationary member. An antireflective coating is applied to portions of the micromechanical device to limit undesired reflection from the device. A passivation or lubrication layer is applied to the device to reduce stiction between the deflectable member and the stationary member. An insulator layer is utilized between the antireflective coating and the lubrication layer to prevent photoelectric-induced breakdown of the lubrication layer.

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.
