摘要： This invention is a residue-free vapor-phase process for etching metallic layers during the manufacturing of integrated circuits. The process comprises contacting a portion of the metallic surface to be etched with an effective amount of an etching agent comprising a .beta.-diketone or .beta.-ketoimine dispersed in an atmosphere capable of oxidizing the metal to be removed at a temperature sufficient to form a volatile metal-ligand complex. The volatile metal-ligand complex is sublimed from the surface thereby etching successive layers of the metal.

摘要： This invention is a vapor-phase process for cleaning metal-containing contaminants from the surfaces of integrated circuits and semiconductors between the numerous fabricating steps required to manufacture the finished electronic devices. The process comprises contacting the surface to be cleaned with an effective amount of a cleaning agent comprising a carboxylic acid selected from acetic acid or formic acid at a temperature sufficient to form volatile metal-ligand complexes on the surface of the substrate to be cleaned. The volatile metal-ligand complexes are sublimed from the surface of the substrate providing a clean, substantially residue-free surface.

摘要： This invention is a vapor-phase process for cleaning metal-containing contaminants from the surfaces of integrated circuits and semiconductors between the numerous fabricating steps required to manufacture the finished electronic devices. The process employs cleaning agents comprising an effective amount of a partially halogenated or fully halogenated linear or branched carboxylic acid having from 2 to about 10 carbon atoms wherein the halogen is selected from fluorine or chlorine. The process comprises contacting the surface to be cleaned with an effective amount of the desired cleaning agent at a temperature sufficient to form volatile metal-ligand complexes on the surface of the substrate to be cleaned. The volatile metal-ligand complexes are sublimed from the surfaces of the substrate providing a clean, substantially residue-free surface.

摘要： A residue-free fluxing process wherein the active fluxing agent comprises a .beta.-diketone or .beta.-ketoimine ligand. Such ligands react with surface metal oxides on workpieces to be soldered to form volatile metal-ligand complexes as reaction products which are sublimed from the surface leaving essentially no residue on the workpieces. The fluxing agents can be utilized in gas-phase processes wherein the workpieces are contacted with an effective amount of one or more ligands which are dispersed in a carrier gas or solvent or by incorporating the ligands into an alloy-vehicle mixture for use as conventional creams or pastes. The invention eliminates the need for post-reflow cleaning using solvents since no flux residue remains on the workpieces to be soldered following volitilization of the metal-ligand complex.

摘要： The present invention addresses the use of at least partially fluorinated organometallic compounds in reactive deposition applications. More specifically, the present invention addresses the use of the fluoroorganometallic compounds M(CF.sub.3).sub.3, M(CF.sub.2 CF.sub.3).sub.3, or any M(C.sub.n F.sub.(2n+1)).sub.3-y H.sub.y compound where (y.ltoreq.2), M(CH.sub.2 CF.sub.3).sub.3 or any fluoroalkyl organometallics of the general formula M(C.sub.n H.sub.[(2n+1)-x] F.sub.x).sub.3-y H.sub.y, where y.ltoreq.2; x has a value 1.ltoreq.x.ltoreq.2n+1; and M=As, P, or Sb, in processes requiring deposition of the corresponding element. These uses include a number of different processes; the organometallic vapor phase epitaxy of compound semiconductor materials such as GaAs, InP, AlGaAs, InSb, etc.; doping of SiO.sub.2 or borosilicate based glasses to enhance the reflow properties of the glass; in-situ n-type doping of silicon epitaxial material; sourcing of arsenic or phosphorus for ion implantation; chemical beam epitaxy; and diffusion doping into electronic materials such as silicon dioxide, silicon and polycrystalline silicon. These types of materials generally have high volatilities, low toxicities, labile metal-ligand bonds, and stable decomposition products.Specifically, the use of tris-trifluoromethyl arsenic (As(CF.sub.3).sub.3) as a substitute for arsine in the manufacture of silicon integrated circuits, Group III-V compound semiconductors, optoelectronics and other electronic devices has been identified.

摘要： The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.
