Abstract:
Methods and apparatuses for a deposition system are provided to deposit a thin coating layer on flat substrates, such as semiconductors or panels. In an embodiment, liquid supplied rollers accepting liquid media provide liquid chemicals to the substrates for coating the substrates. The liquid delivery system can control the flow and the pressure of the liquid to achieve optimum process condition with minimum excess waste. In another embodiment, rollers with non-uniform distribution of liquid media provide a non-uniform thickness profile on the substrates, which can be used to compensate for the non-uniformity of subsequent processes.
Abstract:
The present invention relates to a process for covering a substrate with a polymer film characterized in that, prior to the deposition of said polymer film, nanoparticles are adsorbed electrostatically onto the surface of said substrate to be covered.
Abstract:
The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS) that can be modified as desired. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of objects, referred to herein as Object A (Solid A or Liquid A). Use of an external stimuli or degradation of the Liquid B can be utilized to change the characteristics of SLIPS structures reversibly or irreversibly that may be desired in a number of different applications. Numerous characteristics, such as adhesion, optical, mechanical, and the like, can be dynamically changed.
Abstract:
Disclosed in this specification is a method for aligning nanostructures. A substrate is coated with a liquid solution comprising particles. Before the solution is cured, circularly-polarized light is applied to the substrate to induce a magnetic field in the particles. A low strength magnetic field is then applied. The induced magnetic field of the particles aligns with the applied magnetic field. The solution is permitted to cure while simultaneously exposed to both the circularly-polarized light and the applied magnetic field. The resulting composite retains the particle alignment.
Abstract:
The present invention relates to a functional film and a method for manufacturing the same, the functional film being organically and inorganically laminated to have a desired function such as high gas barrier performance and having high adhesiveness between inorganic and organic layers. The organic layer on top of the inorganic layer contains an organic solvent; an organic compound formed of the organic layer; and a silane coupling agent with a concentration between 0.1 and 25 percentages by mass excluding the organic solvent, the organic layer uses a coating material not containing a pH controller, and the organic layer is formed through curing via a heating process after coating.
Abstract:
In one aspect, a method for fabricating metal structures in two or three dimensions is disclosed, which includes providing a mixture of a polymer, a metal precursor and a solvent, and applying the mixture to a surface of a substrate. The applied mixture can then be cured (e.g., via a heat treatment) to generate a polymeric layer (e.g., a polymeric film) with ions associated with the metal precursor distributed therein. Subsequently, radiation (e.g., radiation pulses) at a wavelength to which the polymeric layer is substantially transparent is focused onto at least one location of the polymeric layer so as to cause chemical reduction of metal ions associated with the metal precursor within at least a portion of that location, thereby generating at least one metalized region.
Abstract:
The invention relates to a method for enhancing a metallic coating on a steel strip or steel plate, the coating being melted by heating to a temperature above the melting temperature of the material of the coating, the heating taking place by irradiation of the surface of the coating with electromagnetic radiation having a high power density over a limited irradiation time of not more than 10 μs, and the mandated irradiation time and the energy density introduced into the coating by the electromagnetic radiation being selected such that the coating melts completely over its entire thickness down to the boundary layer with the steel strip, thereby forming a thin alloy layer at the boundary layer between the coating and the steel strip. The invention further relates to a steel strip or steel plate having a metallic coating, more particularly a coating of tin, zinc or nickel, in which, at the boundary layer between the steel and the coating, an alloy layer which is thin—compared with the thickness of the coating—and at the same time is dense, and is composed of iron atoms and atoms of the coating material, is formed, the thickness of the alloy layer corresponding to an alloy-layer add-on of less than 0.3 g/m2.
Abstract:
The invention relates to a process for heating an organic coating applied to a number of substrates, especially a mirror, laser radiation being applied to the organic coating while the substrates run past without stopping. This process especially allows paints or inks to be dried or baked with little heat transfer to the substrate.

Abstract:
Apparatuses and processes for maskless deposition of electronic and biological materials. The process is capable of direct deposition of features with linewidths varying from the micron range up to a fraction of a millimeter, and may be used to deposit features on substrates with damage thresholds near 100° C. Deposition and subsequent processing may be carried out under ambient conditions, eliminating the need for a vacuum atmosphere. The process may also be performed in an inert gas environment. Deposition of and subsequent laser post processing produces linewidths as low as 1 micron, with sub-micron edge definition. The apparatus nozzle has a large working distance—the orifice to substrate distance may be several millimeters—and direct write onto non-planar surfaces is possible.
