Chip scale package with specific contact ball arrangement
A recently granted patent (Publication Number: US11887924B2) discloses a chip scale package (CSP) design that includes a semiconductor die, two sets of CSP contact balls or bumps positioned within the perimeter of the die, and a channel routing region devoid of any contact balls or bumps. The CSP is designed to be mounted directly on a substrate of a host device, with the contact balls or bumps facilitating electrical coupling. The unique feature of this CSP is the presence of a channel routing region created by a discontinuity in the arrangement of contact balls or bumps, allowing for efficient signal routing within the package.
Furthermore, the patent also covers a substrate arrangement designed to receive the CSP, comprising two sets of substrate contact pads and a channel routing region with signal routing channels in a metal layer of the substrate. The channel routing region facilitates the efficient transfer of signals between the CSP and the substrate, enhancing the overall performance of the electronic device. Additionally, the substrate includes a second metal layer connected to the first metal layer through vias, further optimizing signal transmission within the package. Overall, this patented CSP and substrate arrangement offer a novel and efficient solution for electronic devices requiring compact and high-performance packaging.
