  • Patent number: 8889233
    Abstract: The present invention addresses provides improved methods of preparing a low-k dielectric material on a substrate. The methods involve multi-step ultraviolet curing processes in which UV intensity, wafer substrate temperature and other conditions may be independently modulated at each step. In certain embodiments, a film containing a structure former and a porogen is exposed to UV radiation in a first step to facilitate removal of the porogen and create a porous dielectric film. In a second step, the film is exposed to UV radiation to increase crosslinking within the porous film. In certain embodiments, the curing takes place in a multi-station UV chamber wherein UV intensity and substrate temperature may be independently controlled at each station.

  • Patent number: 8784931
    Abstract: A method of manufacturing ULSI wiring in which wiring layers are separately formed via a diffusion prevention layer and an insulating interlayer portion made of SiO2. The method comprises the steps of treating, with a silane compound, a SiO2 surface of the insulating interlayer portion on which the diffusion layer is to be formed, performing catalyzation with an aqueous solution containing a palladium compound, forming the diffusion prevention layer by electroless plating, and then forming the wiring layer on this diffusion prevention layer. A capping layer may be formed on the wiring layer by electroless plating. Consequently, a diffusion prevention layer having good adhesive properties can be formed through a simple wet process, and, the wiring layer can directly be formed on this diffusion prevention layer by a wet process. The capping layer can also be directly formed on the wiring layer by electroless plating.

  • Patent number: 8778462
    Abstract: A composite sheet comprises a substrate and a multi-layer coating on its outer surface, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes an olefin group and a moisture curable group, such as an isocyanate or silane group. The function of the polymeric layer includes protecting the metal layer from corrosion. A production process for the composite sheet includes depositing the precursor and exposing it to both beam radiation and moisture, which respectively promote polymerization and curing at different sites of the precursor. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation.

Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.
