Abstract:
In a surface treatment method of treating the surface of a material to be treated, by irradiating with light the material to be treated and a mediating material in contact with each other, the mediating material itself causes substantially no interaction upon irradiation with light. The surface of the material to be treated is treated by provision of a chemical reaction field, in which a substituent of the material to be treated and an atom of atomic group of the mediating material is induced by excitation, by irradiating with light by using the logical product of the contact interface between the material to be treated and the mediating material and the light irradiation region, thereby causing and progressing bonded state transition.
Abstract:
The described deposition systems are designed to accommodate new precursors and chemical processes used for transport polymerization and chemical vapor deposition. The systems consist primarily of a reactor, a liquid injector or gas mass flow controller, a cracker and a deposition chamber under sub-atmospheres pressure. The cracker utilizes one or more types of energy, including heat, photons, and plasmas. This invention is especially useful for preparing F-PPX (fluorinated poly(para-xylylenes) and other fluorinated polymer thin films for intermetal dielectric (IMD) and interlevel dielectric (ILD) applications in the manufacture of integrated circuits with features

The present invention provides a method for forming a coating film, which comprises ejecting a curable coating composition from a spray gun, spray-coating the ejected composition while applying thereto an active energy beam, and heat-curing the resulting coating film, wherein the curable coating composition contains an epoxy group-containing resin (A) and a photo-induced cationic polymerization initiator (B).
Abstract:
An apparatus for light curing of an adhesive resin coating on a continuous string-like linear product is shown. It consists of an elongated chamber having a light reflective inner side wall and removable end caps. The product coated with the adhesive resin is passed through the chamber through transverse slots formed in the end caps. The ultraviolet curing light is injected into the chamber by a light guide inserted through the peripheral side wall. Nitrogen gas may be also passed through the chamber to enhance the curing process of the resin.
Abstract:
An improvement in the photochemical vapor deposition apparatus for the preparation of a functional deposited film on a substrate by exciting and decomposing, or polymerizing a raw material as by way of a photochemical reaction, which comprises a reaction chamber with a raw material gas introducing means and an exhaust means, a radiant light transmissive window and a means to supply a light energy through the light transmissive window to the raw material gas introduced into the reaction space of the reaction chamber. The improvement comprises providing the above apparatus with a means to irradiate an infrared energy ray containing a wavelength having a vibrational absorption power for the raw material gas molecule concurrently with the irradiation of light energy.The improved photochemical vapor deposition apparatus enables one to stably and repeatedly prepare a desired functional deposited film of high quality and having a wealth of practically applicable characeristics at an improved film deposition rate without foreign matter resulting from the raw material gas being deposited on the inner face of the light transmissive window.
Abstract:
A process for treating metal surfaces to obtain improved susceptibility to bonding with adhesive compositions is disclosed. A metal surface is oxidized with a halogen to form a monolayer of halide ions on the surface. The halide ions are then exchanged with azide ions to form an azide monolayer on the metal surface. Upon contact of the treated surface with an adhesive composition, the azide layer may be thermally or photochemically decomposed to form active nitrene species, which react to bond the adhesive composition to the metal surface.

A method for forming a deposited film comprises forming in a vacuum chamber housing a substrate therein a deposited film containing silicon on the substrate by subjecting a gas represented by the general formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4, can be the same or different and are each independently hydrogen or a hydrocarbon group, to polymerization.
Abstract:
A THIN, CONTINUOUS FILM IS FORMED ON A SUBSTRATE BY ULTRAVIOLET SURFACE PHOTOPOLYMERIZATION OF A MATERIAL IN THE GASEOUS PHASE. THE MATERIAL IS SELECTED FROM VARIOUS ANHYDRIDES AND DIANHYDRIDES. SUCH FILMS, WHICH CAN BE SELECTIVELY FORMED AS ELECTRICALLY INSULATING OR ELECTRICALLY CONDUCTIVE, ARE USEFUL AS COATINGS ON METALIC AND NONMETALLIC SUBSTRATES, AND FOR CORROSION PROTECTION. THE ELECTRICALLY INSULATING FILMS ARE USEFUL FURTHER AS CAPACITOR DIELECTRICS, CRYOGENIC DEVICE INSULATION, INSULATION FOR MICROELECTRIC DEVICES, AND PRIMER OR INSULATION ON ELECTRI-
CALLY CONDUCTIVE WIRE, WHILE THE ELECTRICALLY CONDUCTIVE FILMS CAN ALSO BE EMPLOYED AS CONDUCTIVE LAYERS IN MICROELECTRIC DEVICES.
