  • Patent number: 12677450
    Abstract: An improved silicon carbide (SiC) super junction (SJ) MOSFET having at least two buried P-shield (BPS) regions facing each other for gate oxide electric-field and saturation current reductions is disclosed. The two BPS regions are spaced apart from a body region and formed either adjoining sidewalls or below a bottom of a P column region. Moreover, a saturation current pitching (SCP) structure formed in a Junction Field Effect Transistor (JFET) region sandwiched between the two BPS regions limits saturation current of the device in a forward conduction stage for the short-circuit capability improvement.

  • Publication number: 20260127176
    Abstract: In examples, a query management system maintains a query schema for a structured data source. The query schema includes a collection of query templates, where each query template specifies at least one condition. When a mutation in an underling data source is detected, the query management system generates an invalidation command for a corresponding set of cached keys. Based on attributes of the mutated data set, the query template can enable the use of wildcard designations to for purpose of identifying cache keys that are to be invalidated as a result of the mutated data set.
