Abstract:
A method of manufacturing an array of planar wafer level metal posts includes plating an array of posts within a photoresist (PR) pattern mold on a substrate of a first wafer. Stripping the PR pattern mold from the substrate and array of posts. Applying an oxide layer, at a temperature of below 150 degrees Celsius, over a surface of the first wafer. Applying chemical-mechanical polishing (CMP) to planarize the oxide layer and the array of posts.

Claim (Index 11):
A method of manufacturing a bonded wafer assembly with Indium interconnections comprising:\n a) providing a first wafer with a substrate layer, an insulating layer, and a metal seed layer, the metal seed layer connected to the substrate layer by vias extending through a first plurality of holes in the insulating layer; b) applying a photoresist (PR) pattern mold over the metal seed layer such that a second plurality of holes through the PR pattern mold align with the vias; c) plating Indium within the second plurality of holes in the PR pattern mold to form an array of Indium posts on the first wafer; d) stripping the PR pattern mold; e) etching a portion of the metal seed layer to singulate the array of Indium posts; f) applying an oxide layer, at a temperature below 150 degrees Celsius, over a surface of the first wafer; g) applying chemical-mechanical polishing (CMP) to form a planar surface, the planar surface including the array of Indium posts and the oxide layer; h) performing steps a)-g) to create a second wafer; i) aligning the Indium posts of the first and second wafers; and j) bonding the first wafer and the second wafer together to form the bonded wafer assembly.
