Methods of forming planarized multilevel metallization in an integrated circuit
Abstract:
A method is provided for forming a semiconductor device that reduces metal-stress-induced photo misalignment by incorporating a multi-layered anti-reflective coating over a metal layer. The method includes providing a substrate with a conductive layer formed over the substrate, depositing a multi-layered anti-reflective coating (including alternating layers of titanium and titanium nitride), defining a plurality of conductive lines in connection with a first etching step, depositing a dielectric layer, and defining at least one via in connection with a second etching step.
