摘要: Etching a layer over a substrate is provided. The substrate is placed in a plasma processing chamber. A first gas is provided to an inner zone within the plasma processing chamber. A second gas is provided to the outer zone within the plasma processing chamber, where the outer zone surrounds the inner zone and the first gas is different than the second gas. Plasmas are simultaneously generated from the first gas and second gas. The layer is etched, where the layer is etched by the plasmas from the first gas and second gas.

摘要: A method for designing an etch recipe is provided. An etch is performed, comprising providing an etch gas with a set halogen to carbon ratio, forming a plasma from the etch gas, and etching trenches over via. Via faceting is measured. The halogen to carbon ratio is reset according to the measured via faceting, where the halogen to carbon ratio is increased if too much faceting is measured and the halogen to carbon ratio is decreased if too little faceting is measured. The previous steps are repeated until a desired amount of faceting is obtained.
