Abstract:
A method is provided for fabricating micro-electromechanical devices. Generally, the method includes: (i) forming a device layer over a sacrificial layer on a surface of a substrate; (ii) patterning the device layer to form a number of ribbons each including a long axis parallel to the surface of the substrate and a middle section between support structures at both ends of the ribbon; (iii) partially removing the sacrificial layer to undercut the number of ribbons; (iv) forming a reflective coating of a reflective material on the number of ribbons; and (v) releasing the middle section of at least one of the number of ribbons by removing the sacrificial layer. Undercutting the ribbons prior to forming the reflective coating reduces build-up of material on sidewalls of the sacrificial layer facilitating release of the ribbons. Other embodiments are also disclosed.

Abstract:
In one embodiment, a sacrificial layer is deposited over a base layer. The sacrificial layer is used to define a subsequently formed floating metal structure. The floating metal structure may be anchored into the base layer. Once the floating metal structure is formed, the sacrificial layer surrounding the floating metal structure is etched to create a unity-k dielectric region separating the floating metal structure from the base layer. The unity-k dielectric region also separates the floating metal structure from another floating metal structure. In one embodiment, a noble gas fluoride such as xenon difluoride is used to etch a sacrificial layer of polycrystalline silicon.
Abstract:
A grating light valve is provided with a plurality of spaced reflective ribbons, spatially arranged over a semiconductor substrate, the ribbons and substrate being provided with reflective surfaces. The grating light valve is configured to optimize the conditions for constructive and destructive interference with an incident light source having a given wavelength. In a preferred embodiment, one set of ribbons is moveable with respect to the substrate and the second set of ribbons. The substrate is typically provided with a protective layer, which may be thermally grown silicon dioxide or other dielectric. A conductive trace is provided on the dielectric layer and grounded through the dielectric layer to the substrate, comprising a conductive trace for easy release of charge otherwise trapped in the dielectric layer.
Abstract:
A grating light valve has with a plurality of spaced reflective ribbons are spatially arranged over a substrate with reflective surfaces. The grating light valve is configured to optimized the conditions for constructive and destructive interference with an incident light source having a wavelength λ. The grating light valve preferably has a set of movable active ribbons alternating between the set of stationary bias ribbons. The active ribbons and the bias ribbons are spatially separated over the substrate surface such that reflective regions of the substrate surface correspond to the spaces between the ribbons. The ribbons and reflective regions of the substrate optically and geometrically optimized for to generate the conditions for constrictive and destructive interference with the incident light source. Accordingly, ribbons of the active ribbons are configured with reflective cross sections that are is approximately equal to the sum of the diffraction cross sections of the bias ribbons and the reflective regions of the substrate. In operation, active ribbons are moved by a multiple of λ/4 to switch between the conditions for constructive and destructive interference.
