Patent ID: 11942402
Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. An isolator device package, comprising:
a leadframe having a split die attachment pad (DAP) including a first die pad and a second die pad;
a capacitive isolator device on the first die pad comprising a laminate die comprising a dielectric laminate material with a metal laminate layer on one side of the dielectric laminate material, the metal laminate layer being a patterned layer providing a first plate;
a first integrated circuit (IC) comprising a substrate having a semiconductor surface including circuitry including at least one of a transmitter and a receiver, the first IC including a top metal layer providing at least a second plate coupled to a node in the circuitry, with at least one passivation layer on the top metal layer;
a non-conductive die attach (NCDA) material for attaching a side of the dielectric laminate material opposite the metal laminate layer to the first IC so that the first plate is at least partially over the second plate to provide a capacitor;
a second IC mounted on the second die pad comprising a substrate having a semiconductor surface including circuitry configured for a function including at least one of a transmitter and a receiver; and
packaging material covering the capacitive isolator device, the first IC, the second IC and at least a portion of the lead frame.
