Abstract

Implementations of semiconductor packages may include: a first substrate having a first dielectric layer coupled between a first metal layer and a second metal layer; a second substrate having a second dielectric layer coupled between a third metal layer and a fourth metal layer. A first die may be coupled with a first electrical spacer coupled in a space between and coupled with the first substrate and the second substrate and a second die may be coupled with a second electrical spacer coupled in a space between and coupled with the first substrate and the second substrate.
