  • Patent number: 9508616
    Abstract: A method for forming a multilayer structure comprises the steps of: depositing a first polymerizable layer on a substrate; applying microwave energy to the polymerizable layer while monitoring at least one property of the layer; and, ending the application of microwave energy when the monitored property indicates that the polymerizable layer has reached a desired degree of cure. The property monitored may be optical, e.g., Raman spectrum, or electrical, e.g., dielectric loss. This process control strategy lowers the overall thermal budget, and is especially suitable for curing polymer films on silicon. The method may be used repetitively to cure multiple layers of polymeric material when a thicker film is needed.

  • Patent number: 9481011
    Abstract: An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

  • Patent number: 9447501
    Abstract: A non-aqueous photocurable composition contains dispersed carbon-coated metal particles in an organic diluent in an amount of at least 10 weight %. The dispersed carbon-coated metal particles have a median diameter equal to or less than 0.6 ?m, and are dispersed using a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. The median diameter of the dispersed particles is determined using a dynamic light scattering method. Moreover, when the non-aqueous composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20° C.

  • Patent number: 9372241
    Abstract: A method by which portions of a wafer level fabrication can be selectively heated by forming plasmon generating layers of specific size, shape, orientation and material on the fabrication and then illuminating the formation with electromagnetic radiation of such wavelength and polarization as will optimally be absorbed by the plasmon generating layers so as to generate plasmons therein. The generated plasmons thereupon produce thermal energy which is transferred to portions of the fabrication with which the plasmon generation layer has thermal contact. This method is particularly advantageous for producing multiple anneals and different magnetic pinning directions for the anti-ferromagnetic pinning layer in each of an array of GMR or TMR devices. In that process, the anti-ferromagnetic layer must be raised above its Curie temperature at which point it loses its anti-ferromagnetic properties and can have a magnetization imposed by application of an external magnetic field.
