  • Publication number: 20200203290
    Abstract: In described examples of an integrated circuit (IC) there is a substrate of semiconductor material having a first region with a first transistor formed therein and a second region with a second transistor formed therein. An isolation trench extends through the substrate and separates the first region of the substrate from the second region of the substrate. An interconnect region having layers of dielectric is disposed on a top surface of the substrate. A dielectric polymer is disposed in the isolation trench and in a layer over the backside surface of the substrate. An edge of the polymer layer is separated from the perimeter edge of the substrate by a space.

  • Publication number: 20200168534
    Abstract: In some examples, a multi-chip module (MCM), comprises a first and a second die-attach pad (DAP); a first die comprising a first set of microelectronic devices; a second die comprising a first capacitor and a second capacitor; and a third die comprising a second set of microelectronic devices, where the first and second dies are positioned on the first DAP, and the third die is positioned on the second DAP. The first set of microelectronic devices couples to the first capacitor via a first inter-die connection and the second set of microelectronic devices couples to the second capacitor via a second inter-die connection.

  • Publication number: 20200161225
    Abstract: Described herein is a technology or a method for fabricating a flip-chip on lead (FOL) semiconductor package. A lead frame includes an edge on surface that has a geometric shape that provides a radial and uniform distribution of electric fields. By placing the formed geometric shape along an active die of a semiconductor chip, the electric fields that are present in between the lead frame and the semiconductor chip are uniformly concentrated.

  • Publication number: 20200027848
    Abstract: A packaged multichip device includes a first IC die with an isolation capacitor utilizing a top metal layer as its top plate and a lower metal layer as its bottom plate. A second IC die has a second isolation capacitor utilizing its top metal layer as its top plate and a lower metal layer as its bottom plate. A first bondwire end is coupled to one top plate and a second bondwire end is coupled to the other top plate. The second bondwire end includes a stitch bond including a wire approach angle not normal to the top plate it is bonded to and is placed so that the stitch bond's center is positioned at least 5% further from an edge of this top plate on a bondwire crossover side compared to a distance of the stitch bond's center from the side opposite the bondwire crossover side.

  • Patent number: 10345397
    Abstract: An integrated fluxgate device has a magnetic core on a control circuit. The magnetic core has a volume and internal structure sufficient to have low magnetic noise and low non-linearity. A stress control structure is disposed proximate to the magnetic core. An excitation winding, a sense winding and a compensation winding are disposed around the magnetic core. An excitation circuit disposed in the control circuit is coupled to the excitation winding, configured to provide current at high frequency to the excitation winding sufficient to generate a saturating magnetic field in the magnetic core during each cycle at the high frequency. An isolation structure is disposed between the magnetic core and the windings, sufficient to enable operation of the excitation winding and the sense winding at the high frequency at low power.

  • Patent number: 9893008
    Abstract: An electronic isolation device is formed on a monolithic substrate and includes a plurality of passive isolation components. The isolation components are formed in three metal levels. The first metal level is separated from the monolithic substrate by an inorganic PMD layer. The second metal level is separated from the first metal level by a layer of silicon dioxide. The third metal level is separated from the second metal level by at least 20 microns of polyimide or PBO. The isolation components include bondpads on the third metal level for connections to other devices. A dielectric layer is formed over the third metal level, exposing the bondpads. The isolation device contains no transistors.
