Abstract
A method for fabricating an interposer includes providing an interposer substrate with at least one slot or aperture therethrough and forming at least one upwardly protruding dam on the interposer substrate, adjacent to the slot or aperture. The upwardly protruding dam or dams may at least partially surround the slot or aperture. Accordingly, the upwardly protruding dam or dams may laterally confine encapsulant material over the slot or aperture and over any intermediate conductive elements extending through the slot or aperture. Programmed material consolidation processes, such as stereolithography, may be used to form the at least one upwardly protruding dam.
Claims22
A method for fabricating an interposer, comprising:
- providing at least one interposer substrate that includes at least one slot therethrough;
- and
- forming at least one upwardly protruding dam at least partially around the at least one slot on a surface of the at least one interposer.
A method for fabricating an interposer, comprising:
- providing at least one interposer substrate that includes at least one slot or aperture therethrough;
- and
- selectively fabricating at least one upwardly protruding dam adjacent to at least a portion of the at least one slot or aperture under control of a program.
