    摘要: A process of forming an electronic device can include patterning a semiconductor layer to define an opening extending to an insulating layer, wherein the insulating layer lies between a substrate and the semiconductor layer. After patterning the semiconductor layer, the opening can have a bottom, and the semiconductor layer can have a sidewall and a surface. The surface can be spaced apart from the insulating layer, and the sidewall can extend from the surface towards the insulating layer. The process can also include depositing a nitride layer within the opening, wherein depositing is performed using a PECVD technique. The process can further include densifying the nitride layer. The process can still further include removing a part of the nitride layer, wherein a remaining portion of the nitride layer can lie within the opening and be spaced apart from the surface.

    摘要: A wander reduction mechanism in an HDSL pulse-stuffing synchronization system provides a more precise measure of the phase of the incoming asynchronous signal than is obtained in conventional schemes, in which the only information available is the presence or absence of stuffing pulses. An auxiliary phase comparator and phase adjuster are incorporated into the synchronizer-multiplexer to generate a reference data clock (derived from the synchronized data clock), so that the incoming unsynchronized data clock can be tracked. As the clock is iteratively phase-adjusted, the respective changes are accumulated. At the end of a prescribed measurement interval, the net contents of the accumulator are encoded and transported over the synchronous digital data communication channel to the receiver. By decoding this sequence information, the desynchronizer is able to generate a desynchronized data clock having the same number of net phase adjustments during a measurement period as the reference clock at the synchronizer.

    摘要: A mechanism is provided for reducing stiction in a MEMS device by forming a near-uniform silicon carbide layer on silicon surfaces using carbon from TEOS-based silicon oxide sacrificial films used during fabrication. By using the TEOS as a source of carbon to form an antistiction coating, all silicon surfaces can be coated, including those that are difficult to coat using standard self-assembled monolayer (SAM) processes (e.g., locations beneath the proof mass). Controlled processing parameters, such as temperature, length of time for annealing, and the like, provide for a near-uniform silicon carbide coating not provided by previous processes.
