  • Publication number: 20240250009
    Abstract: Embedded trace substrates (ETS) having an ETS metallization layer with T-shaped interconnects with reduced-width embedded metal traces, and related integrated circuit (IC) packages and fabrication methods. The ETS includes an outer ETS metallization layer that includes T-shaped interconnects for supporting input/output (I/O) connections between the ETS and another opposing package substrate. To increase density of I/O interconnections, the pitch of the embedded metal traces in the ETS metallization layer is reduced. The T-shaped interconnects also each include an additional metal contact pad that is coupled to a respective embedded metal trace to increase the height of the embedded metal trace to eliminate a vertical connection gap between the ETS and an opposing package substrate.
