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.

A method includes forming a hard mask over a low-k dielectric layer, and patterning the hard mask to form an opening. A stress tuning layer is formed over the low-k dielectric layer and in physical contact with the hard mask. The stress tuning layer has an inherent stress, wherein the inherent stress is a near-zero stress or a tensile stress. The low-k dielectric layer is etched to form a trench aligned to the opening, wherein the step of etching is performed using the hard mask as an etching mask.

A interconnect structure includes a first etch stop layer over a substrate, a dielectric layer over the first etch stop layer, a conductor in the dielectric layer, and a second etch stop layer over the dielectric layer. The dielectric layer contains carbon and has a top portion and a bottom portion. A difference of C content in the top portion and the bottom portion is less than 2 at %. An oxygen content in a surface of the conductor is less than about 1 at %.

A interconnect structure includes a conductive layer formed in a dielectric layer. An adhesion layer is formed between the dielectric layer and a substrate. The adhesion layer has a carbon content ratio greater than a carbon content ratio of the dielectric layer.
摘要:
In the formation of an interconnect structure, a metal feature is formed in a dielectric layer. An etch stop layer (ESL) is formed over the metal feature and the dielectric layer using a precursor and a carbon-source gas including carbon as precursors. The carbon-source gas is free from carbon dioxide (CO2). The precursor is selected from the group consisting essentially of 1-methylsilane (1MS), 2-methylsilane (2MS), 3-methylsilane (3MS), 4-methylsilane (4MS), and combinations thereof.
