Stiffener with embedded passive components

摘要

Systems and methods for preventing warpage of a semiconductor substrate in a semiconductor package. A continuous or uninterrupted stiffener structure is designed with a recessed groove, such that passive components, such as, high density capacitors are housed within the recessed groove. The stiffener structure with the recessed groove is attached to the semiconductor substrate using anisotropic conductive film (ACF) or anisotropic conductive paste (ACP). The stiffener structure with the recessed groove surrounds one or more semiconductor devices that may be formed on the semiconductor substrate. The stiffener structure with the recessed groove does not extend beyond horizontal boundaries of the semiconductor substrate.

1. A method of forming a stiffener for a semiconductor package, the method comprising:
forming a recessed groove in a stiffener; embedding a passive component within the recessed groove; attaching the stiffener with the embedded passive component to a first surface of a substrate; and forming leads in the passive component and connecting the leads to a power line and a ground connection derived from a predetermined power distribution network (PDN) layout on the substrate.
