    摘要: Semiconductor packages and methods to fabricate thereof are described. A decoupling assembly is disposed between a package substrate and a circuit board. The decoupling assembly engages in response to a stimulus such that a semiconductor die is de-coupled from a socket and a circuit board. The decoupling assembly engages in response to a stimulus such that a semiconductor die is decoupled from a substrate. A decoupling assembly includes a clamping device, springs, and shape memory alloy rods. The shape memory alloy rods are actuators that generate motion or a pre-programmed shape to apply force when thermally excited. When the thermal excitation or other stimulus is removed, the shape memory alloy rods tend to return to their original shape, thus relieving any load or motion generated.
