Tungsten Nitride Powder / Targets (WN and WN2) General Description:
Tungsten nitride (WN2) is an inorganic compound, a nitride of tungsten. It is a ceramic material. It is electrically conductive. It is a very hard solid material. It has brown color. It decomposes in water.
Tungsten Nitride Powder / Tungsten Nitride Targets (WN and WN2) Typical Chemical Purities Available:
a) Tungsten nitride (WN) is another film used for conductive layers or barrier layers within integrated circuit manufacturing. Its use is not as common as pure tungsten films or titanium nitride films but appears to have much promise in the future as geometries shrink. It provides compatibility for applications using barriers in layers of W/WN and WSix / WN.
b) It is used in microelectronics as a contact material, for conductive layers, and barrier layers between silicon and other metals, eg. tungsten or copper. It is less commonly used than titanium nitride or tungsten films.
