US Patent 11908780 Semiconductor package with solder standoff

A semiconductor package includes a leadframe including a die pad and a plurality of lead terminals. A vertical semiconductor device is attached on a first side by a die attach material to the die pad. A first clip is on the first vertical device that is solder connected to a terminal of the first vertical device on a second side opposite to the first side providing a first solder bonded interface, wherein the first clip is connected to at least a first of the lead terminals. The first solder bonded interface includes a first protruding surface standoff therein that extends from a surface on the second side of the first vertical device to physically contact the first clip.
