Abstract:
An embodiment related to a method for forming a device is disclosed. The method includes providing a package substrate having a first die attach pad (DAP) and a first bond pad, forming a first conductive die-substrate bonding layer on the first DAP, and attaching a first major surface of a first die to the first DAP. The first die includes a first die contact pad on a second major surface of the first die. A first conductive clip-die bonding layer with spacers is formed on the first die contact pad of the first die. A first conductive clip-substrate bonding layer is formed on the first bond pad of the package substrate. The method also includes attaching a first clip bond to the first die and the first bond pad. The first clip bond includes a first horizontal planar portion attached to the first die over the first die contact pad and a second vertical portion attached to the first bond pad.
