Abstract:
1. A method of forming a through substrate interconnect, comprising: forming a passivation dielectric over a back-side of a semiconductor substrate; after forming the passivation dielectric, etching through the passivation dielectric and then into semiconductive material of the substrate from the substrate back-side to form a via; applying a liquid dielectric over the passivation dielectric and into the via to line only an elevationally outermost portion of sidewalls of the via; solidifying the liquid dielectric within the via; vapor depositing a dielectric material to within the via to line over the solidified dielectric within the via and to line over sidewall portions of the via received elevationally inward of the solidified dielectric within the via; and forming conductive material within the via over the vapor deposited dielectric material and forming a through substrate interconnect with the conductive material.
