Abstract
A method of forming a through-substrate via includes forming a through-substrate via opening at least partially through a substrate from one of opposing sides of the substrate. A first material is deposited to line and narrow the through-substrate via opening. The first material is etched to widen at least an elevationally outermost portion of the narrowed through-substrate via opening on the one side. After the etching, a conductive second material is deposited to fill the widened through-substrate via opening. Additional implementations are disclosed. Integrated circuit substrates are disclosed independent of method of manufacture.
