摘要： The invention is carried out in a plasma reactor for processing a semiconductor wafer, the plasma reactor having a chamber for containing a processing gas and having a conductor connected to an RF power source for coupling RF power into the reactor chamber to generate from the processing gas a plasma inside the chamber, the chamber containing at least one surface exposed toward the plasma and susceptible to contamination by particles produced during processing of the wafer, the invention being carried out by promoting, during processing of the wafer, bombarding of particles from the plasma onto the one surface to remove therefrom contaminants deposited during processing of the wafer. Such promoting of bombarding is carried out by providing an RF power supply and coupling, during processing of the wafer, RF power from the supply to the one surface. The coupling may be performed by a capacitive cleaning electrode adjacent the one surface, the capacitive cleaning electrode connected to the RF power supply. The capacitive cleaning electrode preferably is disposed on a side of the one surface opposite the plasma so as to be protected from contact with the plasma. Alternatively, the coupling may be carried out by a direct electrical connection from the RF power supply to the one surface.

摘要： An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. In one embodiment the first chamber includes an interior surface that has been roughened to at least 100 Ra and the second chamber includes an interior surface that has a roughness of less than about 32 Ra. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a barrier layer and a feature in the substrate to be contacted into the first chamber where the dielectric layer is etched in a process that encourages polymer formation over the roughened interior surface of the chamber. The substrate is then transferred from the first chamber to the second chamber under vacuum conditions and, in the second chamber, is exposed to a reactive plasma such as oxygen to strip away the photoresist mask deposited over the substrate. After the photoresist mask is stripped, the barrier layer is etched through to the feature to be contacted in the second chamber of the multichamber substrate processing system using a process that discourages polymer formation over the relatively smooth interior surface of the second chamber. All three etching steps are performed in a system level in situ process so that the substrate is not exposed to an ambient between steps. In some embodiments the interior surface of the first chamber has a roughness between 100 and 200 Ra and in other embodiments the roughness of the first chamber's interior surface is between 110 and 160 Ra.

摘要： The present disclosure pertains to a method for plasma etching of low k materials, particularly polymeric-based low k materials. Preferably the polymeric-based materials are organic-based materials. The method employs an etchant plasma where the major etchant species are generated from a halogen other than fluorine and oxygen. The preferred halogen is chlorine. The volumetric (flow rate) ratio of the halogen:oxygen in the plasma source gas ranges from about 1:20 to about 20:1. The atomic ratio of the halogen:oxygen preferably falls within the range from about 1:20 to about 20:1. When the halogen is chlorine, the preferred atomic ratio of chlorine:oxygen ranges from about 1:10 to about 5:1. When this atomic ratio of chlorine:oxygen is used, the etch selectivity for the low k material over adjacent oxygen-comprising or nitrogen-comprising layers is advantageous, typically in excess of about 10:1. The plasma source gas may contain additives in an amount of 15% or less by volume which are designed to improve selectivity for the low k dielectric over an adjacent material, to provide a better etch profile, or to provide better critical dimension control, for example. When the additive contains fluorine, the amount of the additive is such that residual chlorine on the etched surface of the low k material comprises less than 5 atomic %.

摘要： Disclosed herein is a post-etch treatment for plasma etched metal-comprising features in semiconductor devices. The post-etch treatment significantly reduces or eliminates surface corrosion of the etched metal-comprising feature. It is particularly important to prevent the formation of moisture on the surface of the feature surface prior to an affirmative treatment to remove corrosion-causing contaminants from the feature surface. Avoidance of moisture formation is assisted by use of a high vacuum; use of an inert, moisture-free purge gas; and by maintaining the substrate at a sufficiently high temperature to volatilize moisture. The affirmative post-etch treatment utilizes a plasma to expose the etched metal-comprising feature to sufficient hydrogen which is in a kinetic state permitting reaction with residual halogen-comprising residues on the etched surface, while maintaining the etched feature surface at a temperature which supports volatilization of the byproducts of a reaction between the active hydrogen species and the halogen-comprising residues. For an etched copper surface, if moisture forms on the etched surface prior to an affirmative treatment to remove corrosion-causing contaminants, it is very important to avoid contact of the etched surface with pollutants which are capable of forming copper carbonates and/or copper sulfates.

摘要： A first embodiment of the present invention pertains to a method of patterning a semiconductor device conductive feature while permitting easy removal of any residual masking layer which remains after completion of the etching process. A multi-layered masking structure is used which includes a layer of high-temperature organic-based masking material overlaid by either a patterned layer of inorganic masking material or by a layer of patterned high-temperature imageable organic masking material. The inorganic masking material is used to transfer a pattern to the high-temperature organic-based masking material and is then removed. The high-temperature organic-based masking material is used to transfer the pattern and then may be removed if desired. This method is also useful in the pattern etching of aluminum, even though aluminum can be etched at lower temperatures. A second embodiment of the present invention pertains to a specialized etch chemistry useful in the patterning of organic polymeric layers such as low k dielectrics, or other organic polymeric interfacial layers. This etch chemistry is useful for mask opening during the etch of a conductive layer or is useful in etching damascene structures where a metal fill layer is applied over the surface of a patterned organic-based dielectric layer. The etch chemistry provides for the use of etchant plasma species which minimize oxygen, fluorine, chlorine, and bromine content.

摘要： Copper can be pattern etched at acceptable rates and with selectivity over adjacent materials using an etch process which utilizes a solely physical process which we have termed "enhanced physical bombardment". Enhanced physical bombardment requires an increase in ion density and/or an increase in ion energy of ionized species which strike the substrate surface. To assist in the removal of excited copper atoms from the surface being etched, the power to the ion generation source and/or the substrate offset bias source may be pulsed. In addition, when the bombarding ions are supplied from a remote source, the supply of these ions may be pulsed. Further, thermal phoresis may be used by maintaining a substrate temperature which is higher than the temperature of a surface in the etch chamber. It is also possible to use a chemically reactive species in combination with the physical ion bombardment without causing copper corrosion problems, so long as the concentration of the chemically reactive ion component is sufficiently low that the etching is carried out in a physical bombardment dominated etch regime.
