Anode The electrode in device out of which electrons flow out of and return to the circuit. | Arc An electrical breakdown of gas which produces an ongoing plasma discharge resulting from a current flowing through normally nonconductive media such as air. | Baking the chamber (250 °C-400 °C) removes water or hydrocarbons adsorbed to the walls. |
Cathode The electrode at which electrons go into a cell, tube or diode. | Ceramics Inorganic non-metallic materials. | Coercivity The intensity of the applied magnetic field required to reduce the magnetization of that material to zero after the magnetization of the sample has been driven to saturation. |
Compression Fittings A fitting pressed against a pipe so tightly that no water may leak through. | Conductive A fitting pressed against a pipe so tightly that no water may leak through. | Electron Density The measure of the number of electrons being present in a given volume. |
Flange An external or internal rib or rim, used to add strength or to hold something in place. | Glow Discharge A plasma formed by passing an electric current through a gas - usually argon. | Insulating Prevents the flow of electrical charges. |
Ion An atom with a net electric charge. | Lines of Force The curve whose tangent gives the direction of the field at that point. | Magnetic Field A physical phenomenon produced by both an electric current and/or the orbit and spin of electrons in an atom. |
Substrate The base material to be coated with a thin film. | Target The solid source of material to be deposited through a sputtering process. | Thin Film Deposition Any technique used to deposit a thin film of material onto a substrate or previously deposited materials. |
Magnetron Sputtering Uses magnetic fields to confine plasma to the region closest to the target plate, maintaining a higher ion density and creating a higher electron/ion collision rate, thus increasing the sputter yield. | Metals An element that readily forms ions and creates metallic bonds. | NdFeB Magnets Made from a combination of neodymium, iron and boron and are 30% stronger than other rare-earth magnets. |
O-ring A loop of elastomer with a round cross section used as a mechanical seal. | Out-gassing The slow release of a gas that was trapped, frozen or absorbed in some material. | Permanent magnet A magnet that does not rely upon outside influences to generate their magnetic field. |
Plasma A state of matter which contains an equal number of positive and negative charges. | Power density The amount of power delivered by an energy source, divided by some measure of the source's surface area. | Rare-earth magnet A permanent magnet, stronger in magnitude than ferrite or ceramic magnets. |
RF Shielding The protection of sensitive electrical equipment from external radio frequency electromagnetic radiation by enclosing it in a conductive metal such as a wire mesh. | Short circuit An accidental low-resistance connection between two nodes of an electrical circuit that are different voltages. | Sputtering The vacuum process during which energized plasma ions strike a target composed of the desired coating materials and causes the atoms from that target to eject with enough energy to travel to and bond with a substrate to form a thin film. |
Thin Films A layer of material. | Threaded A ridge running in a spiral down the length of a cylinder which turns rotation into linear movement. | Torr A millimeter of mercury used as a unit of pressure. |
Turbulent water flow A flow regime characterized by chaotic property changes, including low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time. | UHV Requires the use of special materials, extreme cleanliness, and baking the entire system to remove water and other trace gases. | Utilization The proportion of a target used compared to its total resources. |
Vacuum Chamber A rigid enclosure from which air and other gases are removed by a vacuum pump. | ||
