Abstract: A method of fabricating an electonic device which comprises a step of etching a sacrificial layer with an etchant comprising a noble gas fluoride, e.g. Xenon Fluoride (Xe F2). The efficiency of the etching process may be increased in various ways, and the cost of an etching process may be decreased. Unused etchant may be isolated and recirculated during the etching process. Etching byproducts may be collected and removed from the etching system during the etching process. Components of the etchant may be isolated and used to general additional etchant. Either or both of the etchant or the layers being etched may also be optimized for a particular etching process.

Abstract: This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a light input edge into which light is injected and transverse edges transverse to the light input edge. The transverse edges are smooth and act as specular reflectors. The light input edge is rough and provides a diffusive interface. The light emitters are adjacent and centered along the light input edge, with the pitch of the light emitters being about ?L, where ?L is the distance between the transverse edges divided by the number of light emitters. The diffusive light input edge can diffuse light entering into the light guide, and the transverse edges can reflect light with a low level of artifacts and the reflections also act as virtual light sources to facilitate a highly uniform distribution of light within the light guide. The light guide can be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light can be applied to illuminate a display.

Abstract: This disclosure provides systems, methods and apparatus for an electromechanical system. In one aspect, an electromechanical interferometric modulator system includes a substrate and a plurality of interferometric modulators (IMODs). At least two different IMOD types correspond to different reflected colors. Each IMOD has an optical stack, an absorber layer, a movable reflective layer, where the movable reflective layer has at least open and collapsed states, and an air gap defined between the movable reflective layer and the optical stack in the open state. The optical stacks define different optical path lengths for each of the different IMOD types by way of different transparent layer thickness and/or material, while the air gap has the same size when in the open state. The IMODs reflect different colors in the closed state and a common appearance in the open state. Use of two absorbers aids in defining the common appearance in the open state and can also improve color saturation.

Abstract: This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide includes a light turning film (128) over an optically transmissive supporting layer (129). In some implementations, the light turning film may be formed of a material deposited in the liquid state. In some implementations, the light turning film may be formed of a photodefinable material, which may be glass, such a spin-on glass, or may be a polymer. In some other implementations, the glass is not photodefinable. The light turning film may have indentations (131) that define light turning features and a protective layer may be formed over those indentations. The protective layer may also be formed of a glass material, such as spin-on glass. The light turning features in the light guide film may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.
