摘要： Methods of this invention relate to filling gaps on substrates with a solid dielectric material by forming a flowable film in the gap. The flowable film provides consistent, void-free gap fill. The film is then converted to a solid dielectric material. In this manner gaps on the substrate are filled with a solid dielectric material. According to various embodiments, the methods involve reacting a dielectric precursor with an oxidant to form the dielectric material. In certain embodiments, the dielectric precursor condenses and subsequently reacts with the oxidant to form dielectric material. In certain embodiments, vapor phase reactants react to form a condensed flowable film.

摘要： The present invention provides a SiC material, formed according to certain process regimes, useful as a barrier layer, etch stop, and/or an ARC, in multiple levels, including the pre-metal dielectric (PMD) level, in IC applications and provides a dielectric layer deposited in situ with the SiC material for the barrier layers, and etch stops, and ARCs. The dielectric layer can be deposited with different precursors as the SiC material, but preferably with the same or similar precursors as the SiC material. The present invention is particularly useful for ICs using high diffusion copper as a conductive material. The invention may also utilize a plasma containing a reducing agent, such as ammonia, to reduce any oxides that may occur, particularly on metal surfaces such as copper filled features. The invention also provides processing regimes that include using an organosilane as a silicon and carbon source, perhaps independently of any other carbon source or hydrogen source, and preferably in the absence of a substantial amount of oxygen to produce a SiC with a dielectric constant of less than 7.0. This particular SiC material is useful in complex structures, such as a damascene structure and is conducive to in situ deposition, especially when used in multiple capacities for the different layers, such as the barrier layer, the etch stop, and the ARC and can include in situ deposition of the associated dielectric layer(s).

摘要： A method of depositing and etching dielectric layers having low dielectric constants and etch rates that vary by at least 3:1 for formation of horizontal interconnects. The amount of carbon or hydrogen in the dielectric layer is varied by changes in deposition conditions to provide low k dielectric layers that can replace etch stop layers or conventional dielectric layers in damascene applications. A dual damascene structure having two or more dielectric layers with dielectric constants lower than about 4 can be deposited in a single reactor and then etched to form vertical and horizontal interconnects by varying the concentration of a carbon:oxygen gas such as carbon monoxide. The etch gases for forming vertical interconnects preferably comprises CO and a fluorocarbon, and CO is preferably excluded from etch gases for forming horizontal interconnects.

摘要： An apparatus for converting PFC gases exhausted from semiconductor processing equipment to less harmful, non-PFC gases. One embodiment of the apparatus includes a silicon filter and a plasma generation system. The plasma generation system forms a plasma from the effluent PFC gases. Constituents from the plasma react with silicon and/or oxygen in the filter and convert the effluent PFC gases to less harmful, non-PFC gaseous products and byproducts. Another embodiment includes a plasma generation system and a particle trapping and collection system. The particle trapping and collection system traps silicon containing residue from deposition processes that produces such residue, and the plasma generation system forms a plasma from the effluent PFC gases. Constituents from the plasma react with the collected residue to convert the effluent PFC gases to less harmful, non-PFC gaseous products and byproducts.

摘要： A method and apparatus for reducing oxidation of an interface of a semiconductor device thereby improving adhesion of subsequently formed layers and/or devices is disclosed. The semiconductor device has at least a first layer and a second layer wherein the interface is disposed between said first and second layers. The method includes the steps of providing the first layer having a partially oxidized interface; introducing a hydrogen-containing plasma to the interface; reducing the oxidized interface and introducing second-layer-forming compounds to the hydrogen-containing plasma. A concomitant apparatus (i.e., a semiconductor device interface) has a first insulating layer, one or more conductive devices disposed within the insulating layer, the insulating layer and conductive devices defining the interface, wherein the interface is treated with a continuous plasma treatment to remove oxidation and deposit a second layer thereupon. The insulating layer of the interface is selected from oxides and nitrides and is preferably a nitride.

摘要： This invention provides a stable process for depositing films which include silicon and nitrogen, such as antireflective coatings of silicon oxynitride. Nitrogen is employed to permit lower flow rates of the process gas containing silicon, thereby reducing the deposition rate and providing better control of film thickness. Additionally, the use of nitrogen stabilizes the process, improving film uniformity, and provides a higher-quality film. The invention is capable of providing more accurate and easier fabrication of structures requiring uniformly thin films containing silicon, nitrogen, and, optionally, oxygen, such as antireflective coatings.

摘要： A method and apparatus for depositing an etch stop layer. The method begins by introducing process gases into a processing chamber in which a substrate is disposed. An etch stop layer is then deposited over the substrate. An overlying layer is then deposited over the etch stop layer. The etch stop layer substantially protects underlying materials from the etchants used in patterning the overlying layer. Moreover, the etch stop layer also possesses advantageous optical characteristics, making it suitable for use as an antireflective coating in the patterning of layers underlying the etch stop layer.
