Abstract: A bumpless hybrid organic glass interposer. One or more high density pattern (HDP) routing layers are placed on a functional, thin, carrier, separate from the intended organic substrate patch or package. The HDP layer(s) is/are then attached to the substrate package. The interposers achieve electrical connections between the HDP layer and underlying routing layer of the substrate package by utilizing a self-align dry etch process through landing pads connected to the HDP routing.

Abstract: Through-glass vias (TGVs) are formed without the use of a planarization step to planarize the TGV fill material after filling holes that extend through a glass layer with the fill material. After the holes are filled with the fill material, the fill material is etched and the glass layer is etched. After etching of the glass is performed, the top and bottom surfaces of the glass layer are recessed relative to the top and bottom surfaces of the fill material in the holes, resulting in formation of fill material stubs. TGV pads are then formed on the fill material stubs. The resulting pads can have protrusions that extend away from a surface of the glass layer. If the TGVs are plated through-holes, a portion of the metal lining the inner wall of a TGV hole can extend past a surface of the glass layer and into a TGV pad.
