Abstract

An embodiment related to a device. The device includes a first die with first and second die surfaces. The second die surface is bonded to a first die attach pad (DAP) disposed on a first substrate surface of a package substrate and the first die surface includes a first die contact pad. The device also includes a first clip bond including a first clip bond horizontal planar portion attached to the first die contact pad on the first die surface, and a first clip bond vertical portion disposed on an edge of the first clip bond horizontal planar portion. The first clip bond vertical portion is attached to a first substrate bond pad on the first substrate surface. The device further includes a first conductive clip-die bonding layer with spacers on the first die contact pad of the first die. The first conductive clip-die bonding layer bonds the first clip bond horizontal planar portion to the first die contact pad, and the spacers maintain a uniform Bond Line Thickness (BLT) of the first conductive clip-die bonding layer.
