Abstract
A method of lithography patterning includes forming a mask layer on a material layer and forming a capping layer on the mask layer. The capping layer is a boron-containing layer with a higher resistance to an etching reaction of patterning process of the material layer. By adapting the boron-containing layer as the capping layer, the thickness of the mask layer can be thus reduced. Hence, a better gap filling for forming an interconnect metallization in the material layer could be achieved as well.
