    摘要: A new design and fabrication process of an elastomer spatial light modulator (eSLM). The present invention resolves many known challenges and enables the eSLM to operate as programmable masks for the EUV lithography systems. Bottom electrodes are deposited and patterned on an insulation layer. A sacrificial layer is then deposited, patterned and polished on top of the bottom electrodes. A nitride shell forms a protection layer that prevents out-gassing and degradations of elastomer during operations. The sacrificial layer is removed, forming a cavity. An elastomer is injected at one end of the cavity and pulled into it by capillary forces. In an embodiment, the eSLM comprises a 2-D array of elastomer pillars, each containing a capacitive actuator with an elastomer as the supporting and dielectric structure. A stack of Mo/Si multilayer mirror is deposited on the surface to achieve a high reflectivity about 70% or more in EUV.

    摘要: A method of fabricating a self-aligned vertical combdrive is described. The method includes the steps of etching in a semiconductor wafer a first comb with a coarse set of teeth. A second semiconductor wafer is bonded to the first set of teeth. A set of accurately positioned teeth is etched in the second wafer with teeth overlapping the teeth in the first comb. The lower teeth are etched using the overlapping teeth as a mask to assure proper alignment. One variation in this fabrication method whereby the first coarse comb teeth are etched on semiconductor-on-insulator instead, allows creation of double-sided comb actuators with increased torsional deflection range. Another variation to this fabrication method that keeps the electrically isolated upper masking teeth allows creation of dual-mode vertical comb actuators after an initial assembly step.

    摘要: A cross-connect switch for fiber-optic communication networks employing a wavelength dispersive element, such as a grating, and a stack of regular (non-wavelength selective) cross bar switches using two-dimensional arrays of micromachined, electrically actuated, individually-tiltable, controlled deflection micro-mirrors for providing multiport switching capability for a plurality of wavelengths. Using a one-dimensional micromirror array, a fiber-optic based MEMS switched spectrometer that does not require mechanical motion of bulk components or large diode arrays can be constructed with readout capability for WDM network diagnosis or for general purpose spectroscopic applications.
