Abstract: Embodiments of the present disclosure relate to a semiconductor package, a method of forming the package and an electronic device. For example, the semiconductor package may comprise a first substrate assembly comprising a first surface and a second surface opposite the first surface. The semiconductor package may also comprise one or more chips connected or coupled to the first surface of the first substrate assembly by a first thermally and electrically conductive connecting material. In addition, the semiconductor package further comprises a second substrate assembly comprising a third surface and a fourth surface opposite the third surface, the third surface and the first surface being arranged to face each other, and the third surface being connected to one or more chips by a second thermally and electrically conductive connecting material. At least one of the first surface and the third surface is shaped to have a stepped pattern to match a surface of the one or more chips.

Abstract: An adjustable socket structure contains a body including a first groove, a second groove, a first notch, a number of slots; a plurality of paws, each including a sliding block, and the sliding block including a first hole; a number of connecting rods, each being movably fixed in the second groove and including a first axial shank and a second axial shank; a driving shaft including an axial portion and a disk portion, wherein the axial portion includes a square bore, and the disk portion is rotated in the first groove and includes an outer diameter larger that the axial portion and three second holes so that the driving shaft is rotated to actuate the paws to move in the slots respectively by using the connecting rods; a helical retaining ring retained in the first notch to abut against a rear end of the disk portion of the driving shaft.
