  • Publication number: 20200105648
    Abstract: A semiconductor package assembly having a connecting clip disposed on both a first material stack and a second material stack having different thicknesses and disposed on a conducting substrate. This connecting clip has a first portion disposed on to the first material stack and second portion disposed on the second material stack, such that the surfaces of the first portion and second portion opposite the conducting substrate are at the same perpendicular distance from the conducting substrate. For example, in some implementations, when the thickness of the second material stack is smaller than the thickness of the first material stack, the second portion of the connecting clip may include a vertical support disposed on the second material stack to equalize the heights of the surfaces of the first portion and second portion of the connecting clip.
