  • Patent number: 11810786
    Abstract: A method for fabricating a semiconductor device includes following steps: A patterned mask layer including a plurality of standing walls and a covering part is formed on a surface of a semiconductor substrate, wherein two adjacent standing walls define a first opening exposing a part of the surface, and the covering part blankets the surface. A first patterned photoresist layer is formed to partially cover the covering part. A first etching process is performed to form a first trench in the substrate, passing through the surface and aligning with the first opening. A portion of the patterned mask layer is removed to form a second opening exposing another portion of the surface. A second etching process is performed to form a second trench in the substrate and define an active area on the surface. The depth of the first trench is greater than that of the second trench.

    Abstract: A peer-to-peer decentralized software configuration manager is described. The peer-to-peer system provides a crowdsourced mechanism to determine and recommend the efficient software configurations. A computer system may subscribe to a ring or group of network connected computers. Once subscribed, the computer system receives a ring data structure that may include one or more software configuration entries. The ring data structure is accessible to each subscribed computer system to the currently installed software configurations and document the relative success or failure of those configurations. The ring data structure may be utilized to identify a more efficient or user friendly software configuration that is currently installed and utilized by a subscribed computer system.
