Abstract: In one general aspect, a method can include forming a recess and a mesa in a metal layer associated with a substrate, and disposing a first portion of a conductive-bonding component on the mesa and a second portion of the conductive-bonding component in the recess. The method can include disposing a semiconductor component on the conductive-bonding component such that the second portion of the conductive-bonding component is disposed between an edge of the semiconductor component and a bottom surface of the recess.

Abstract: A package includes a semiconductor die attached to a die attach pad by a first sinter bond. The package further includes a clip having a first end and a second end. The first end of the clip is attached to a device contact pad on the semiconductor die by a second sinter bond and the second end of the clip is attached to a post of a lead by a joint. The package further includes a mold body encapsulating the semiconductor die.

Abstract: A die-attach process that creates a bond strength sufficient to hold a die to a substrate while it is handled before being permanently attached is disclosed. The die-attach process includes forming locking features in a metal layer of a substrate so a bond at the die-substrate interface is strengthened. The locking features may include a plurality of cavities or slots formed in a metal layer of the substrate. The cavities and slots can increase a surface area and provide anchor points for a die-attach film placed between the die and the substrate.

Abstract: In one general aspect, an apparatus can include a semiconductor component, a substrate including a recess, and a conductive-bonding component. The conductive-bonding component is disposed between the semiconductor component and the substrate. The conductive-bonding component has a first thickness between a bottom of the recess and a bottom surface of the semiconductor component greater than a second thickness between the top of the substrate and the bottom surface of the semiconductor component.
