Abstract
A semi-flexible component carrier includes a stack having at least one electrically conductive layer structure and at least one electrically insulating layer structure The layer structures are stacked on top of each other in a stacking direction s. A recess extends from a first main surface of the stack into the stack and extends only partially into one of the at least one electrically insulating layer structure so that an electrically insulating layer structure having a stepped portion is formed. The stepped portion provides a flexible region of the stack with respect to a rigid region of the stack.

A semi-flexible component carrier, comprising:
- a stack comprising at least one electrically conductive layer structure and at least one electrically insulating layer structure, wherein the layer structures are stacked on top of each other in a stacking direction;
- a recess
- extending from a first main surface of the stack into the stack and
- extending only partially into one of the at least one electrically insulating layer structure so that an electrically insulating layer structure having a stepped portion is formed,
- wherein the stepped portion provides a flexible region of the stack with respect to a rigid region of the stack.
A method of forming a semi-flexible component carrier, comprising:
- forming a stack comprising at least one electrically conductive layer structure and at least one electrically insulating layer structure, wherein the layer structures are stacked on top of each other in a stacking direction;
- forming a recess
- extending from a first main surface of the stack into the stack and
- extending only partially into one of the at least one electrically insulating layer structure so that an electrically insulating layer structure having a stepped portion is formed,
