Abstract:
A method for creating a functional polymer coating on a substrate in vacuum from a deposited monomer material in absence of oxygen and/or radiation from a radiation source. The substrate may be preliminarily activated with inert gas to form an activated layer thereon. The method may include depositing a fluorine containing monomer having a first CF 3 :CF 2 ratio, and forming, on the substrate, the self-assembled polymer coating that has a second CF 3 :CF 2 ratio, where the first and second CF 3 :CF 2 ratios are equal.

There is provided a barrier film having a substrate, a low thermal conductivity organic layer and an inorganic stack. The inorganic stack will include a low thermal conductivity non-metallic inorganic material layer and a high thermal conductivity metallic material layer.
Abstract:
A method of manufacturing a patterned crystal structure for includes depositing an amorphous material. The amorphous material is modified such that a first portion of the amorphous thin-film layer has a first height/volume and a second portion of the amorphous thin-film layer has a second height/volume greater than the first portion. The amorphous material is annealed to induce crystallization, wherein crystallization is induced in the second portion first due to the greater height/volume of the second portion relative to the first portion to form patterned crystal structures.
Abstract:
The invention relates to medical devices and, more in particular, to medical devices suitable for use as stents that contain an antimicrobial coating and, optionally, a drug customized to patients requirements. The invention also relates to methods for obtaining devices having the above features.
Abstract:
A material processing system that prevents transmission of infrared radiation from its pyrolysis tube to one or more adjacent elements, such as a vaporization chamber or a deposition chamber, is disclosed. Such a material processing system may include at least one conduit with a non-linear element. The non- linear element of such a conduit may preclude the presence of a line-of-sight through the length of the conduit. The non-linear element may also have a shape that enables gas or vapor to flow therethrough with little or no turbulence, which, in embodiments where part or all of the material processing system lacks valves, enables the gas or vapor to flow freely through the material processing system, or at least through the valveless portion thereof.
Abstract:
A pyrolysis tube for use with a material deposition system includes a plurality of channels. The channels may be defined by internal elements of the pyrolysis tube, or by internal elements that form an insert for a conventionally configured pyrolysis tube. One or more of the channels may extend straight through the pyrolysis tube, providing a direct line of sight through the pyrolysis tube. Material deposition systems that include such an insert or pyrolysis tube are also disclosed, as are methods for efficiently pyrolyzing precursor materials at temperatures that are reduced relative to conventional pyrolysis temperatures and/or at rates that are increased relative to conventional pyrolysis rates.
Abstract:
A deposition arrangement (100; 600) for depositing a material on a substrate (110; 640) is described. The deposition arrangement includes a vacuum chamber (120); a roller device (200; 300; 400; 500; 604) within the vacuum chamber (120); and an electrical heating device (61; 220; 320; 420; 520) within the roller device (200; 300; 400; 500; 604), wherein the heating device comprises a first end (250) and a second end (260), and wherein the heating device is held at the first end and at the second end. Also, a method for heating a substrate in a vacuum deposition arrangement is described.
Abstract:
Embodiments described herein are related to methods for processing substrates such as silicon substrates. In some cases, the method may provide the ability to passivate a silicon surface at relatively low temperatures and/or in the absence of a solvent.
