Abstract:
The present disclosure is directed to an apparatus and method of sintering inorganic powder coatings on substrates, and includes a flame and an electric plasma. The method is capable of being used in an open atmospheric environment. The substrate is electrically conductive and is used as one electrode while the flame is used as the other electrode that is moved over the areas of the powder coating to be sintered. An electrical current is used to cause a plasma produced through the flame, resulting in a combined energy and temperature profile sufficient for inorganic powder-powder and powder-substrate bonding. This method is referred to as “flame-assisted flash sintering” (FAFS).

A method and system of modifying a substrate using a plasma are described comprising providing a first electrode and a second electrode; arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis of linear displacement during said movement; and wherein said second electrode is arranged relative to said axis of linear displacement such that said linear movement causes a first section of the portion of substrate to have a greater residence time between the electrodes during said linear displacement than a second section of said portion of the substrate. A method and system of modifying a substrate using a plasma is also described comprising providing a first electrode and a second electrode; arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis of linear displacement during said movement; and further comprising the step of rotating either the substrate or said second electrode about an axis of rotation during said relative linear displacement along said axis, so that a first section of the portion of substrate has a greater residence time between the electrodes than a second section of said portion of substrate.
Abstract:
A porous SiCOH dielectric film in which the stress change caused by increased tetrahedral strain is minimized by post treatment in unsaturated Hydrocarbon ambient. The p-SiCOH dielectric film has more —(CHx) and less Si—O—H and Si—H bonding moieties. Moreover, a stable pSiOCH dielectric film is provided in which the amount of Si—OH (silanol) and Si—H groups at least within the pores has been reduced by about 90% or less by the post treatment. A p-SiCOH dielectric film is produced that is flexible since the pores include stabilized crosslinking —(CHx)— chains wherein x is 1, 2 or 3 therein. The dielectric film is produced utilizing an annealing step subsequent deposition that includes a gaseous ambient that includes at least one C—C double bond and/or at least one C—C triple bond.

In one particular exemplary embodiment, the techniques may be realized as an apparatus for temperature-controlled ion implantation. The apparatus may comprise a platen to hold a wafer in a single-wafer process chamber during ion implantation, the platen including: a wafer clamping mechanism to secure the wafer onto the platen and to provide a predetermined thermal contact between the wafer and the platen, and one or more heating elements to pre-heat and maintain the platen in a predetermined temperature range above room temperature. The apparatus may also comprise a post-cooling station to cool down the wafer after ion implantation. The apparatus may further comprise a wafer handling assembly to load the wafer onto the pre-heated platen and to remove the wafer from the platen to the post-cooling station.

Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. In one embodiment, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst, which may be passive or active. A passive plasma catalyst may include, for example, any object capable of inducing a plasma by deforming a local electric field. An active plasma catalyst can include any particle or high energy wave packet capable of transferring a sufficient amount of energy to a gaseous atom or molecule to remove at least one electron from the gaseous atom or molecule, in the presence of electromagnetic radiation.
Abstract:
A method of forming a titanium silicide nitride (TiSiN) layer on a substrate id described. The titanium silicide nitride (TiSiN) layer is formed by providing a substrate to a process chamber and treating the substrate with a silicon-containing gas. A titanium nitride layer is formed on the treated substrate and exposed to a silicon-containing gas. The titanium nitride (TiN) layer reacts with the silicon-containing gas to form the titanium silicide nitride (TiSiN) layer. The formation of the titanium silicide nitride (TiSiN) layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the titanium silicide nitride (TiSiN) layer may be used as a diffusion barrier for a tungsten (W) metallization process.
