  • Publication number: 20150179544
    Abstract: A semiconductor device has a substrate including a plurality of conductive vias formed vertically and partially through the substrate. An encapsulant is deposited over a first surface of the substrate and around a peripheral region of the substrate. A portion of the encapsulant around the peripheral region is removed by a cutting or laser operation to form a notch extending laterally through the encapsulant to a second surface of the substrate opposite the first surface of the substrate. A first portion of the substrate outside the notch is removed by chemical mechanical polishing to expose the conductive vias. A second portion of the substrate is removed by backgrinding prior to or after forming the notch. The encapsulant is coplanar with the substrate after revealing the conductive vias. The absence of an encapsulant/base material interface and coplanarity of the molded substrate results in less over-etching or under-etching and fewer defects.

    Abstract: A mobile device operable in multiple navigation modes and includes navigation devices, a mode selection module, and a power management module. The navigation devices provide respective data associated with at least one of movement, a position, and a location of the mobile device. Each of the navigation devices is individually operable in an active mode and at least one of an inactive mode and a sleep mode. The mode selection module receives the respective data and selects one of the navigation modes based on the data received from one of the navigation devices. Each of the navigation modes corresponds to different ones of the navigation devices operating in the active mode. The power management module, based on the selected one of the navigation modes, transitions the navigation devices between the active mode and the at least one of the inactive mode and the sleep mode.
