    Abstract: An optical coating, such as anti-reflective coating (ARC) or colored coating for optical devices, suitable especially for mobile devices. The ARC is made up of alternating layers of low refractive index and high refractive index. At least one of the layers, preferably the top layer, is made up of nano-laminate. The nano-laminate is a structure of alternating nano-layers, each nano-layer made out of a material having refractive index similar to the layer it replaces. Optionally, each of the layers are made up of nano-laminates, such that a layer having low refractive index is made up of nano-laminates of nano-layers having low refractive index, while high index layers are made up of nano-lamonate of nano-layers having high refractive index. Each of the nano-layers is of 2-10 nanometer thickness.

    Abstract: A system for transporting substrates and precisely align the substrates horizontally and vertically. The system decouples the functions of transporting the substrates, vertically aligning the substrates, and horizontally aligning the substrates. The transport system includes a carriage upon which plurality of chuck assemblies are loosely positioned, each of the chuck assemblies includes a base having vertical alignment wheels to place the substrate in precise vertical alignment. A pedestal is configured to freely slide on the base. The pedestal includes a set of horizontal alignment wheels that precisely align the pedestal in the horizontal direction. An electrostatic chuck is magnetically held to the pedestal.

    Abstract: A system for processing substrates in plasma chambers, such that all substrates transport and loading/unloading operations are performed in atmospheric environment, but processing is performed in vacuum environment. The substrates are transported throughout the system on carriers. The system's chambers are arranged linearly, such that carriers move from one chamber directly to the next. A conveyor, placed above or below the system's chambers, returns the carriers to the system's entry area after processing is completed. Loading and unloading of substrates may be performed at one side of the system, or loading can be done at the entry side and unloading at the exit side.

    Abstract: The use of non-mass analyzed ion implanter is advantageous in such application as it generates ion implanting at different depth depending on the ions energy and mass. This allows for gaining advantage from lubricity offered as a result of the very light deposition on the surface, and at the same time the hardness provided by the intercalated ions implanted below it, providing benefits for cover glass, low E enhancement, and other similar materials. In further aspects, ion implantation is used to create other desirable film properties such anti-microbial and corrosion resistance.

    Abstract: A sputtering system having a processing chamber with an inlet port and an outlet port, and a sputtering target positioned on a wall of the processing chamber. A movable magnet arrangement is positioned behind the sputtering target and reciprocally slides behinds the target. A conveyor continuously transports substrates at a constant speed past the sputtering target, such that at any given time, several substrates face the target between the leading edge and the trailing edge. The movable magnet arrangement slides at a speed that is at least several times faster than the constant speed of the conveyor. A rotating zone is defined behind the leading edge and trailing edge of the target, wherein the magnet arrangement decelerates when it enters the rotating zone and accelerates as it reverses direction of sliding within the rotating zone.
