    Abstract: The invention provides a fabrication method of batch producing nano-scale structures, such as arrays of silicon pillars of high aspect ratio. The invention also relates to providing arrays of high aspect ratio silicon pillars fabricated using the improved fabrication method. The array of silicon pillars is fabricated from arrays of low aspect ratio pyramid-shaped structures. Mask formed from a hard material, such as a metal mask, is formed on top of each of the pyramid-shaped structures in a batch process. The pyramid-shaped structures are subsequently etched to remove substrate materials not protected by the hard masks, so that a high aspect ratio pillar or shaft is formed on the pyramid-shaped low aspect ratio base, resulting in an array of high aspect ratio silicon pillars.

    Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.

    Abstract: A method of forming a MEMS device (10) includes forming a sacrificial layer (34) over a substrate (12). The method further includes forming a metal layer (42) over the sacrificial layer (34) and forming a protection layer (44) overlying the metal layer (42). The method further includes etching the protection layer (44) and the metal layer (42) to form a structure (56) having a remaining portion of the protection layer formed over a remaining portion of the metal layer. The method further includes etching the sacrificial layer (34) to form a movable portion of the MEMS device, wherein the remaining portion of the protection layer protects the remaining portion of the metal layer during the etching of the sacrificial layer (34) to form the movable portion of the MEMS device (10).
