摘要: A method providing a high aspect ratio through substrate via in a substrate is described. The through substrate via has vertical sidewalls and a horizontal bottom. The substrate has a horizontal field area surrounding the through substrate via. A first metallic barrier layer is deposited on the sidewalls of the through substrate via. A nitridation process converts a surface portion of the metallic barrier layer to a nitride surface layer. The nitride surface layer enhances the nucleation of subsequent depositions. A first metal layer is deposited to fill the through substrate via. A selective etch creates a recess in the first metal layer in the through substrate via. A second barrier layer is deposited over the recess. A second metal layer is patterned over the second barrier layer filling the recess and creating a contact. Another aspect of the invention is a device produced by the method.
