  • Publication number: 20240170384
    Abstract: DSM-LGA using substrates with different surface finish options include copper posts for electrical communication. The copper posts include a height-to-width ratio that cannot be achieved in traditional copper posts, as well as a taper ratio that forms a more rectangular cross section as opposed to traditional copper posts. Additionally, by using copper, the copper posts include a relatively high thermal conductivity (as compared to solder), thus allowing the copper posts to dissipate thermal energy generated by integrated circuits and other processors. Copper posts can take the form of a single, cylindrical post. Alternatively, copper posts can be merged to form a variety of copper structures used for various applications, including I/O, grounding/isolation, and substrate support.
