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.
