| 摘要 |
Package substrates and methods to fabricate therein are described. A package substrate may include conductive layers, vias, dielectric layers and traces fabricated therein, all patterned on one or two sides of a core embedded within a package substrate. For an embodiment, vias and traces may be formed by an ablation process and a subsequent ink printing process. For other embodiments, vias and traces may be formed by various combinations of other processes such as, but not limited to, ablation, ink printing, paste deposition, and laser assisted deposition. For various embodiments, the traces may have aspect ratios greater than 1.
