Abstract: An integrated circuit package includes a first integrated circuit die, a spacer die coupled in the integrated circuit package in a location designed to house a second integrated circuit die, and a package substrate coupled to the first integrated circuit die and to the spacer die.

Abstract: Disclosed embodiments include conductive polygon power and ground interconnects in an infield formed by an electrical contact array. The conductive polygon ground interconnects are orthogonally reticulated an among the conductive polygon power interconnects, for integrated-circuit device packages that provide a low-loss path to active and passive devices, by minimizing resistive loops.

Abstract: Techniques for designing integrated circuit (IC) package substrates are provided. One of the provided techniques include routing a first set of interconnects in a first region of an IC package substrate based on a first routing template and routing a second set of interconnects in a second region of the IC package substrate based on a second routing template. The first routing template is associated with output pins on the IC package substrate while the second routing template is associated with interconnects on at least one IC die of the multiple IC dies. In one scenario, the first routing template is a common routing template. As such, when a different IC die is used with an identical, or otherwise similar, IC package substrate, interconnects associated with output pins on that IC package substrate does not need to be rerouted as they may be routed based on the common routing template.

Abstract: A lead frame for an integrated circuit (IC) package is disclosed. The lead frame includes a center region and a plurality of lead fingers surrounding the center region. The plurality of lead fingers that surrounds the center region defines a periphery region around the center region. A portion of the plurality of lead fingers extends from the center region to hold the center region in place. Tie bars that are typically used to hold the center region in place may not be included in the lead frame.
