摘要: 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. In the T-shape interconnects, their embedded metal traces are reduced in width in a horizontal direction(s) as compared to their respective metal contact pads to provide room for additional metal traces for additional signal routing capacity.

摘要: Certain aspects of the present disclosure generally relate to an embedded trace substrate with partially buried traces, methods for fabrication thereof, and apparatus comprising such an embedded trace substrate. One example method of fabricating an embedded trace substrate generally includes creating a pattern of conductive traces above a dielectric layer and mechanically pressing on the pattern of conductive traces such that lower portions of the conductive traces are buried in the dielectric layer.

摘要: Embedded trace substrate (ETS) with embedded metal traces having multiple thicknesses for integrated circuit (IC) package height control, and related IC packages and fabrication methods. The IC package includes a die that is coupled to a package substrate to provide signal routing paths to the die. The IC package also includes an ETS that includes metal traces embedded in an insulating layer(s) to provide connections for signal routing paths for the IC package. To control (such as to reduce) the height of the IC package, the embedded metal traces embedded in an insulating layer in the ETS are provided to have multiple thicknesses (i.e., heights) in a vertical direction. The embedded metal traces in the ETS whose thicknesses affect the overall height of the IC package by being coupled to interconnects external to the ETS in the vertical direction, can be reduced in thickness to control IC package height.

摘要: Integrated circuit (IC) package substrate with an embedded trace substrate (ETS) layer on a substrate, and related fabrication methods. The package substrate of the IC package includes an ETS layer provided on the substrate to facilitate providing higher density substrate interconnects to provide bump/solder joints for coupling a semiconductor die to the package substrate. ETS interconnects in the ETS layer in the package substrate facilitates die connections having a reduced line-spacing ratio (L/S) (e.g., 5.0 micrometers (μm)/5.0 μm or less) over substrate interconnects in a substrate. In additional exemplary aspects, raised metal pillar interconnects are formed in contact with respective ETS interconnects of the ETS layer of the package substrate to avoid or reduce metal consumption by die solder disposed on metal pillar interconnects of the ETS layer providing bump/solder joints.
