Abstract
A scored green tape (100) is disclosed. The scored green tape comprises a green ceramic material that has a first surface (108) and a second surface (112) opposite the first surface. The first surface and the second surface define a thickness (T) of the scored green tape. The scored green tape further comprises a score track (116) with an ablated region (120) that penetrates the green ceramic material (104) through the first surface. The ablated region is disposed along a contour (124) of the score track that extends parallel to the first surface. The ablated region has a depth from the first surface that is in a range of from about 20% to about 85% of the thickness of the scored green tape. The contour defines a section (128) of the green ceramic material configured to be separated after sintering of the scored green tape. In an exemplary embodiment, the scored green tape is scored via laser ablation.
