Abstract:
1. A method of forming a high density structure, comprising the steps of: providing a substrate wherein the high density structure is to be formed with a release liner, said release liner being self-removable; forming at least one cavity in the substrate through the release liner, said at least one cavity forming at least a part of the high density structure; at least partially filling the at least one cavity with a filler material; sintering the thus formed structure; removing the release liner from the substrate after the step of sintering, wherein an outer surface of a structure provided by the filler material in the at least one cavity is substantially flush with an outer surface of the substrate; providing a second release liner on the surface of the substrate; forming at least one further cavity in the substrate through the second release liner, said at least one further cavity forming a further part of the high density structure; and at least partially filling the at least one further cavity with a further filler material.
