Methods are provided for forming a die package. The method comprises stiffening a flexible substrate to provide a first flexibility of the flexible substrate, forming a mounting element on a first side of the flexible substrate, and mounting a first die on the first side of the flexible substrate to couple the first die to the mounting element. Further, the method comprises mounting a second die on a second side of the flexible substrate and mounting a third die on the second side of the flexible substrate to couple the second and third die to the mounting element, respectively. Furthermore, the method comprises adjusting the stiffening to provide a second flexibility of the flexible substrate that is greater than the first flexibility, and stacking the second die and the third die to provide an overlap of a portion of the second die and a portion of the third die. |
