  • Publication number: 20240274538
    Abstract: Methods for forming microelectronic devices include forming a staircase structure in a stack structure having a vertically alternating sequence of insulative and conductive materials arranged in tiers. Steps are at lateral ends of the tiers. Contact openings of different aspect ratios are formed in fill material adjacent the staircase structure, with some openings terminating in the fill material and others exposing portions of the conductive material of upper tiers of the stack structure. Additional conductive material is selectively formed on the exposed portions of the conductive material. The contact openings initially terminating in the fill material are extended to expose portions of the conductive material of lower elevations. Contacts are formed, with some extending to the additional conductive material and others extending to conductive material of the tiers of the lower elevations. Microelectronic devices and systems incorporating such staircase structures and contacts are also disclosed.

  • Patent number: 10331510
    Abstract: In order to reduce computation time and cost involved with detecting and diagnosing a fault in a system, simplified representations of components of the system are used to estimate valid intervals for state variables at the components. Generic failure rules are configured to compare the estimated valid intervals to related intervals for the same state variables, from either observations or propagations, for overlap. Failure output vectors are generated based on the comparison, and the failure output vectors are compared to diagnostic matrices to determine a source of the fault.

  • Publication number: 20190156438
    Abstract: Production tasks are scheduled to optimize production constraints while taking time varying energy prices into account. An energy management layer (EML) is in communication with a manufacturing domain as well as a smart grid domain. The EML receives information relating to a factory workflow, costs associated with operating units within the factory, and static utility information such as tariff models and incentives. Time variant energy price information is obtained from a utility regarding periodic price levels for a near future timeframe. The workflow is converted to a matrix representation that is acceptable to a mixed integer linear programming (MILP) solver. An algebraic factor representing a tradeoff between energy cost and full-capacity production is minimized to produce production variables which control production and limit production units and tasks to be performed during time slots that are most economically favorable.
