Tungsten electrode used in a gas tungsten arc welding torch Tungsten filament is used in incandescent lightbulbs, where it is heated until it glows Because of its conductive properties and relative chemical inertness, tungsten is also used in electrodes , and in the emitter tips in electron-beam instruments that use field emission guns , such ...

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
Formation of HF is a drawback, as the HF vapor is very aggressive and etches away most materials. Also, the deposited tungsten shows poor adhesion to the silicon dioxide which is the main passivation material in semiconductor electronics. Therefore, SiO 2 has to be covered with an extra buffer layer prior to the tungsten deposition. On the ...
Global interconnects can transmit further, such as over large-area sub-circuits. Consequently, local interconnects may be formed from materials with relatively high electrical resistivity such as polycrystalline silicon (sometimes silicided to extend its range) or tungsten. To extend the distance an interconnect may reach, various circuits such ...
It is a binary file format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form (two-dimensional/2D CAD file format). The data can be used to reconstruct all or part of the artwork to be used in sharing layouts, transferring artwork between different tools, or creating photomasks .
