    摘要: A method of detecting and calibrating dry fluxing metal surfaces of one or more components to be soldered by electron attachment using a gas mixture of reducing gas comprising hydrogen and deuterium, comprising the steps of: a) providing one or more components to be soldered which are connected to a first electrode as a target assembly; b) providing a second electrode adjacent the target assembly; c) providing a gas mixture comprising a reducing gas comprising hydrogen and deuterium between the first and second electrodes; d) providing a direct current (DC) voltage to the first and second electrodes to form an emission current between the electrodes and donating electrons to the reducing gas to form negatively charged ionic reducing gas and molecules of hydrogen bonded to deuterium; e) contacting the target assembly with the negatively charged ionic reducing gas and reducing oxides on the target assembly. Related apparatus is also disclosed.

    摘要: This invention relates to a process for selective removal of materials, such as: silicon, molybdenum, tungsten, titanium, zirconium, hafnium, vanadium, tantalum, niobium, boron, phosphorus, germanium, arsenic, and mixtures thereof, from silicon dioxide, silicon nitride, nickel, aluminum, TiNi alloy, photoresist, phosphosilicate glass, boron phosphosilicate glass, polyimides, gold, copper, platinum, chromium, aluminum oxide, silicon carbide and mixtures thereof. The process is related to the important applications in the cleaning or etching process for semiconductor deposition chambers and semiconductor tools, devices in a micro electro mechanical system (MEMS), and ion implantation systems. Methods of forming XeF2 by reacting Xe with a fluorine containing chemical are also provided, where the fluorine containing chemical is selected from the group consisting of F2, NF3, C2F6, CF4, C3F8, SF6, a plasma containing F atoms generated from an upstream plasma generator and mixtures thereof.
