摘要:
A method is disclosed for reducing metal diffusion in a semiconductor device. After forming a first metal portion over a substrate, a silicon carbon nitro-oxide (SiCNO) layer is deposited on the first metal portion. A dielectric layer is deposited over the SiCNO layer, and an opening is generated in the SiCNO layer and the dielectric layer for a second metal portion to be connected to the first metal portion, wherein the SiCNO layer reduces the diffusion of the first metal portion into the dielectric layer.

摘要:
A method for cleaning residual material from a chemical vapor deposition (CVD) apparatus in situ employing dry etching. There is first employed a high density plasma chemical vapor deposition (HDP-CVD) method to deposit layers of silicon oxide material upon substrates within a chemical vapor deposition reactor apparatus. After removal of substrates, the reactor chamber is closed off. The interior of the reactor is then filled with a gas and a plasma formed therewithin, to which oxygen is added and the reactor allowed to come to an increased temperature and bake for a period of time. The reactor power is then turned off and the reactor evacuated. There is then carried out a normal cleaning step within the reactor chamber employing a reactive gas such as NF3, with greater cleaning efficiency due to the increased temperature caused by the baking step.

A plasma treatment method which is capable of extending the MTF (mean-time-to-failure) of metal interconnects fabricated on a semiconductor wafer substrate, is disclosed. The invention includes providing a trench typically in a dielectric layer on a substrate; depositing a metal in the trench; and exposing the metal to a nitrogen-based plasma. The plasma-treatment step accelerates grain growth and re-orients the grains in the metal to a closely-packed crystal orientation texture which approaches or approximates the crystal orientation texture of copper.
摘要:
A shallow trench isolation (STI) structure for semiconductor devices is formed using a deposited silicon layer formed over a polish stop layer formed over an oxide formed on a substrate. The polish stop layer may be nitride. An opening is formed extending through the deposited silicon layer and the nitride and oxide layers and extending into the substrate. A deposited oxide is formed filling the opening and extending over the top surface of deposited silicon layer. A chemical mechanical polishing operation polishes the deposited silicon layer at a rate faster than the deposited oxide layer to produce an STI with a convex portion extending above the nitride layer. Dishing problems are avoided and the structure may be subsequently planarized.

摘要:
A method for capping over a copper layer. A copper layer is deposited overlying a substrate. The copper surface is treated with hydrogen-containing plasma to remove copper oxides formed thereon, thereby suppressing copper hillock formation. The treated copper surface is treated again with nitrogen-containing plasma to improve adhesion of the copper surface. A capping layer is formed on the copper layer.
