  • Patent number: 11869820
    Abstract: An integrated circuit (IC) includes a substrate including circuitry configured for a function, the circuitry including at least one stress sensitive circuit portion, with at least a portion of nodes in the circuitry electrically coupled to bond pads provided by a top metal layer. A metal wall that is ring-shaped is positioned above the top metal layer that is not electrically coupled to the circuitry. The stress sensitive circuit portion is with at least a majority of its area within an inner area of the substrate that is framed by the metal wall to provide a cavity.

  • Publication number: 20220415824
    Abstract: A semiconductor package includes a semiconductor die including a semiconductor substrate, a strain-sensitive component located within or over a metallization layer of the semiconductor die, wherein a parameter of the strain-sensitive component exhibits a longitudinal shift due to a longitudinal strain and a transverse shift due to a transverse strain, and a mold compound covering the semiconductor die and the strain-sensitive component. The semiconductor package, including the semiconductor die and the mold compound, defines an orthogonal package-induced strain ratio on the strain-sensitive component on the semiconductor die surface. The strain-sensitive component is located such that the longitudinal shift due to package-induced strains offsets the transverse shift due to the package-induced strains.
