    Abstract: A high plasma density etch process for etching an oxygen-containing layer overlying a non-oxygen containing layer on a workpiece in a plasma reactor chamber, by providing a chamber ceiling overlying the workpiece and containing a semiconductor material, supplying into the chamber a process gas containing etchant precursor species, polymer precursor species and hydrogen, applying plasma source power into the chamber, and cooling the ceiling to a temperature range at or below about 150 degrees C. The etchant and polymer precursor species contain fluorine, and the chamber ceiling semiconductor material includes a fluorine scavenger precursor material. Preferably, the process gas includes at least one of CHF3 and CH2F2. Preferably, the process gas further includes a species including an inert gas, such as HeH2 or Ar. If the chamber is of the type including a heated fluorine scavenger precursor material, this material is heated to well above the polymer condensation temperature, while the ceiling is cooled. In some cases, the plasma source power applicator is an inductive antenna overlying the semiconductor ceiling, and the ceiling has a cooling/heating apparatus contacting the ceiling through semiconductor rings. The inductive antenna in this case constitutes inductive elements between adjacent ones of the semiconductor rings.

    Abstract: The magnetron sputtering apparatus of this invention has planar bodies 13 made of a material capable of capturing oxygen and water, heaters 14 to heat the planar bodies 13, an oxygen monitor 15 and others in a load lock chamber 11 and separate chamber 12. After a metal film has been formed on a silicon substrate 18 in a film forming chamber, the substrate is subjected to a heating treatment such that a metal silicide layer is formed. Before the silicon substrate being still hot is transferred to the load lock and separate chambers 11 and 12, oxygen and water in the same chambers have been removed. Through this arrangement it is possible to prevent oxidation of the metal silicide layer, and to form a high melting point silicide layer having a low resistance.

    Abstract: An apparatus and method for scavenging etchant species from a plasma formed of etchant gas prior to the etchant gas entering a primary processing chamber of a plasma reactor. There is at least one scavenging chamber, each of which is connected at an inlet thereof to an etchant gas source and at an outlet thereof to a gas distribution device of the primary processing chamber. Each scavenging chamber has a radiation applicator that irradiates the interior of the scavenging chamber and creates a plasma therein from etchant gas flowing through the chamber from the etchant gas source to the gas distribution apparatus of the primary processing chamber. The applicator uses either an inductive discharge, capacitive discharge, direct current (DC) discharge or microwave discharge to irradiate the interior of the scavenging chamber and ignite the plasma. An etchant species scavenging source is also disposed within the scavenging chamber. This source provides scavenging material that interacts with the plasma to scavenge etchant species created by the dissociation of the etchant gas in the plasma and form etch by-products comprised of substances from both the etchant species and the scavenging source. The scavenging chambers can be employed, as is or in a modified form, as excitation chambers to excite gases at optimal conditions and feed the modified gases into the primary chamber. The scavenging chamber is modified by removing its scavenging source if this source would adversely interact with the gas being excited.

    Abstract: A plasma-processing method used in processes for manufacturing semiconductor devices. During plasma processing, ultraviolet radiation is emitted from a region where a plasma is created. An ultraviolet radiation-blocking means blocks the ultraviolet radiation from impinging on the sample surface to protect it. The blocking means passes particles forming a plasma onto the sample surface. The particles passed through the ultraviolet radiation-blocking plates are implanted into the sample. Alternatively, the processed surface of the sample is etched, or a film is deposited on the processed surface of the sample.

    Abstract: A method and apparatus for reducing particulates in a plasma tool using steady state flows includes a device, operatively coupled to a housing in which an object to be processed is positioned, for generating a plasma flow adjacent the object toward a pumping aperture. A pumping mechanism pumps a medium adjacent the object. The medium supports the plasma and entrains particulates in the plasma away from the object and out the pumping aperture. Magnetic fields, produced by multipole magnets forming a ring cusp, are preferably used to produce the plasma flow which is directed radially away from the object to be processed. In a second embodiment, an array of magnets which form a line cusp is provided to produce an opening through which plasma will flow.
