Through silicon via (TSV) back surface exposure process
ActiveCN103219281AAvoid damagePrevent oxidation and corrosionSemiconductor/solid-state device manufacturingHigh surfaceCopper
The invention discloses a through silicon via (TSV) back surface exposure process. By retaining a substrate above a TSV during the grinding of the back surface of the substrate, the damage to an exposed part of the TSV and the substrate caused by a physical thinning process is avoided, and the ground surface of the substrate with high total thickness variation (TTV) has high surface smoothness, so that the consistency in the subsequent etching process is high. The substrate is etched by an etching solution with high selection ratio of the substrate to a medium layer through a first wet method, the situation of etching of the medium layer and a barrier layer on the TSV for the first time decides whether or not the substrate is etched for the second time and the third time, the exposed part of the TSV has an enough height, and a conductive column of the exposed part is protected from being damaged by the etching solution. A photosensitive material serves as a medium protection layer, and a final TSV exposure structure is etched in an exposure and development manner, so that the corrosion and oxidization of conductive column copper in the conventional process are avoided, and the subsequent processing steps are simplified.
