  • Publication number: 20240145346
    Abstract: A semiconductor device includes a substrate with a conductive pattern. A semiconductor die is electrically connected to the substrate and both the semiconductor die and the substrate are at least partially covered by a package body. In some examples, through-mold vias are formed in the package body to provide electrical signal paths from an exterior surface thereof to the conductive pattern of the substrate. In some examples, through-mold vias are included in the package body to provide electrical signal paths between the semiconductor die and an exterior surface of the package body. In some examples, an interposer is electrically connected to the through-mold vias and may be covered by the package body and/or disposed in spaced relation thereto. In some examples, the interposer may not be electrically connected to the through-mold vias but may have one or more semiconductor dies of the semiconductor device electrically connected thereto.

  • Patent number: 11947132
    Abstract: There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.
