    摘要: An MEMS mirror structure is formed using an etching process that forms sidewall oxide spacers while maintaining the integrity of the oxide layer formed over the reflective layer of the MEMS mirror structure. The discrete mirror structure is formed to include a reflective layer sandwiched between oxide layers and with a protect layer formed over the upper oxide layer. A spacer oxide layer is formed to cover the structure and oxide spacers are formed on sidewalls of the discrete structure using a selective etch process that is terminated when horizontal portions of the spacer oxide layer have cleared to expose the release layer formed below the discrete mirror structure and the protect layer. The superjacent protect layer prevents the spacer oxide etch process from attacking the upper oxide layer and therefore maintains the integrity of the upper oxide layer and the functionality of the mirror structure.

    摘要: A mirror process uses a tungsten passivation layer to prevent metal-spiking induced mirror bridging and improve mirror curvature. A mirror structure is patterned on a first sacrificial layer overlying a substrate. A tungsten passivation layer is then blanket deposited to cover the top and sidewalls of the mirror structure. A second sacrificial layer is formed overlying the tungsten passivation layer. A releasing process with an etchant including XeF2 is performed to remove the second sacrificial layer, the tungsten passivation layer and the first sacrificial layer simultaneously.

    摘要: Disclosed is a method and a system for forming alignment marks on a transparent substrate. A light reflective layer is deposited over an optically transparent substrate of a wafer. A region is defined around an alignment mark on the optically transparent substrate. The light reflective layer is removed from a substantial portion of the transparent substrate excluding the region. In addition, a micro electro-mechanical systems device is disclosed. The device comprises an optically transparent substrate, at least one optically partially transparent alignment mark on the optically transparent substrate, and a plurality of reflective elements or imaging pixels attached to the optically transparent substrate.
