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 ...

GDSII stream format (GDSII), is a binary database file format which is the de facto industry standard for Electronic Design Automation data exchange of integrated circuit or IC layout artwork. [1] It is a binary file format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form (two ...
The first time that A15 structure was observed was in 1931 when an electrolytically deposited layer of tungsten was examined. [2] Discussion of whether the β-tungsten structure is an allotrope of tungsten or the structure of a tungsten suboxide was long-standing, but since the 1950s there has been many publications showing that the material is a true allotrope of tungsten.
HTML Form format HTML 4.01 Specification since PDF 1.5; HTML 2.0 since 1.2 Forms Data Format (FDF) based on PDF, uses the same syntax and has essentially the same file structure, but is much simpler than PDF since the body of an FDF document consists of only one required object. Forms Data Format is defined in the PDF specification (since PDF 1.2).

Tungsten nitride (W 2 N, WN, WN 2) is an inorganic compound, a nitride of tungsten. [1] It is a hard, solid, brown-colored ceramic material that is electrically conductive and decomposes in water. It is used in microelectronics as a contact material , for conductive layers, and barrier layers between silicon and other metals, e.g. tungsten or ...
In semiconductor design, standard-cell methodology is a method of designing application-specific integrated circuits (ASICs) with mostly digital-logic features. Standard-cell methodology is an example of design abstraction, whereby a low-level very-large-scale integration layout is encapsulated into an abstract logic representation (such as a NAND gate).
