A component carrier includes a stack with at least one electrically conductive layer structure and at least one electrically insulating layer structure, a component embedded in the stack, and a via formed in the at least one electrically insulating layer structure along a horizontal path having a length being larger than a horizontal width.

Component carrier with embedded component and horizontally elongated via

A component carrier includes an electrically insulating layer structure, a first electrically conductive layer structure, a second electrically conductive layer structure, and a laser through-hole with an electrically conductive medium filling at least part of the through-hole. The first electrically conductive layer structure covers a first side of the electrically insulating layer structure and has a first window extending through the first electrically conductive layer structure formed by etching using a conformal mask. The second electrically conductive layer structure covers an opposed side of the electrically insulating layer structure and has a second window extending through the second electrically conductive layer structure formed by etching using a conformal mask. The laser through-hole extends through the electrically insulating layer structure. At least a portion of at least one sidewall of the electrically conductive layer structures delimiting the windows is tapered.

Component carrier with electrically conductive layer structures having windows defined by a conformal mask and tapering at least partially

A component carrier and a method of manufacturing a component carrier are provided. The component carrier includes a stack having a front side and a back side, the stack including a plurality of stacked electrically insulating layer structures, a through hole being narrower in its inner portion compared to its exterior portions and extending through the plurality of electrically insulating layer structures so that sidewalls of each of the electrically insulating layer structures delimit respective parts of the through hole, and an electrically conductive filling medium filling at least a part of the through hole.

Component carrier with through hole extending through multiple dielectric layers

A component carrier includes a layer stack formed of an electrically insulating structure and an electrically conductive structure with a bore extending into the layer stack. The bore includes a first bore section with a first diameter and a connected second bore section with a second diameter differing from the first diameter. The component carrier further comprises a thermally conductive material filling substantially the entire bore. The bore is in particular formed by mechanical drilling.
