When northeast Japan was hit by tsunami following a devastating earthquake two weeks ago, we provided an account of the direct impact suffered by Japanese consumer electronics companies including Sony, Panasonic and Toshiba. However, a fortnight later more details have emerged regarding the potential disruption to the supply chain of flat-screen LCD HDTV production – affecting even non-Japanese manufacturers – courtesy of the smart folks over at DisplaySearch.

The California-based display market research and consulting firm has listed several key materials used in the making of LCD TVs, which are likely to run low as a consequence of the natural disaster. Nitrogen Trifluoride (NF3), a gas that is used to clean Chemical Vapour Deposition (CVD) chambers during the manufacturing of TFT LCD panels, was already in short supply prior to the earthquake/ tsunami as gas producers refrained from expanding production capacity due to depressed prices. After Shibukawa city (that houses an NF3 plant owned by Kanto Denka Kogyo which together with Mitsui Chemicals and Central Gas accounts for 30% of the world’s NF3 supply) was hit by the earthquake and ensuing electricity power blackouts, DisplaySearch is predicting a temporary NF3 gas shortage at the very least.

Two Japanese firms, JX Nikko and Mitsui, in combination hold more than 70% share of the global Indium Tin Oxide (ITO) market: the material is a transparent conductor used widely in TFT LCDs. While Mitsui has escaped any direct impact from the earthquake, JX Nikko’s ITO factory – only 80km away from the Fukushima nuclear power reactor – is shut down at this time of writing, prompting fears about supply constraints.

Supply of green pigments used in colour filters may also be affected, as Japanese organic pigment supplier DIC (formerly Dainippon Ink and Chemicals) hinted that its production has been hurt by the earthquake. It appears that connectors made by Hirose and JAE, which transmit power and video signals in LCD television modules, may see some shortages too. That said, DisplaySearch does not expect any significant production delays in the very short term, because most LCD TV panel makers typically stock at least a few weeks’ worth of inventory, which buys them some time to source these materials from alternative suppliers.

Nitrogen trifluoride (NF3) is an inorganic, colorless, non-flammable, toxic gas with a slightly musty odor. It finds increasing use within the manufacturing of flat-panel displays, photovoltaics, LEDs and other microelectronics.greenhouse gas. Its atmospheric burden exceeded 2 parts per trillion during 2019 and has doubled every five years since the late 20th century.

Nitrogen trifluoride did not exist in significant quantities on Earth prior to its synthesis by humans. It is a rare example of a binary fluoride that can be prepared directly from the elements only at very uncommon conditions, such as an electric discharge.Otto Ruff prepared nitrogen trifluoride by the electrolysis of a molten mixture of ammonium fluoride and hydrogen fluoride.nitrogen trichloride, nitrogen tribromide and nitrogen triiodide, all of which are explosive. Alone among the nitrogen trihalides it has a negative enthalpy of formation. It is prepared in modern times both by direct reaction of ammonia and fluorine and by a variation of Ruff"s method.

Nitrogen trifluoride is primarily used to remove silicon and silicon-compounds during the manufacturing of semiconductor devices such as LCD displays, some thin-film solar cells, and other microelectronics. In these applications NF3 is initially broken down within a plasma. The resulting fluorine radicals are the active agents that attack polysilicon, silicon nitride and silicon oxide. They can be used as well to remove tungsten silicide, tungsten, and certain other metals. In addition to serving as an etchant in device fabrication, NF3 is also widely used to clean PECVD chambers.

NF3 dissociates more readily within a low-pressure discharge in comparison to perfluorinated compounds (PFCs) and sulfur hexafluoride (SF6). The greater abundance of negatively-charged free radicals thus generated can yield higher silicon removal rates, and provide other process benefits such as less residual contamination and a lower net charge stress on the device being fabricated. As a somewhat more thoroughly consumed etching and cleaning agent, NF3 has also been promoted as an environmentally preferable substitute for SF6 or PFCs such as hexafluoroethane.

The utilization efficiency of the chemicals applied in plasma processes varies widely between equipment and applications. A sizeable fraction of the reactants are wasted into the exhaust stream and can ultimately be emitted into Earth"s atmosphere. Modern abatement systems can substantially decrease atmospheric emissions.NF3 has not been subject to significant use restrictions. The annual reporting of NF3 production, consumption, and waste emissions by large manufacturers has been required in many industrialized countries as a response to the observed atmospheric growth and the international Kyoto Protocol.

Highly toxic fluorine gas (F2, diatomic fluorine) is a climate neutral replacement for nitrogen trifluoride in some manufacturing applications. It requires more stringent handling and safety precautions, especially to protect manufacturing personnel.

Nitrogen trifluoride is also used in hydrogen fluoride and deuterium fluoride lasers, which are types of chemical lasers. There it is also preferred to fluorine gas due to its more convenient handling properties

Although NF3 has a high GWP, for a long time its radiative forcing in the Earth"s atmosphere has been assumed to be small, spuriously presuming that only small quantities are released into the atmosphere. Industrial applications of NF3 routinely break it down, while in the past previously used regulated compounds such as SF6 and PFCs were often released. Research has questioned the previous assumptions. High-volume applications such as DRAM computer memory production, the manufacturing of flat panel displays and the large-scale production of thin-film solar cells use NF3.

Since 1992, when less than 100 tons were produced, production has grown to an estimated 4000 tons in 2007 and is projected to increase significantly.3 is expected to reach 8000 tons a year by 2010. By far the world"s largest producer of NF3 is the US industrial gas and chemical company Air Products & Chemicals. An estimated 2% of produced NF3 is released into the atmosphere.−2 of IR forcing.3 has risen from about 0.02 ppt (parts per trillion, dry air mole fraction) in 1980, to 0.86 ppt in 2011, with a rate of increase of 0.095 ppt yr−1, or about 11% per year, and an interhemispheric gradient that is consistent with emissions occurring overwhelmingly in the Northern Hemisphere, as expected. This rise rate in 2011 corresponds to about 1200 metric tons/y NF3 emissions globally, or about 10% of the NF3 global production estimates. This is a significantly higher percentage than has been estimated by industry, and thus strengthens the case for inventorying NF3 production and for regulating its emissions.3 emissions to the overall greenhouse gas budget of thin-film Si-solar cell manufacturing is clear.

The UNFCCC, within the context of the Kyoto Protocol, decided to include nitrogen trifluoride in the second Kyoto Protocol compliance period, which begins in 2012 and ends in either 2017 or 2020. Following suit, the WBCSD/WRI GHG Protocol is amending all of its standards (corporate, product and Scope 3) to also cover NF3.

Skin contact with NF3 is not hazardous, and it is a relatively minor irritant to mucous membranes and eyes. It is a pulmonary irritant with a toxicity considerably lower than nitrogen oxides, and overexposure via inhalation causes the conversion of hemoglobin in blood to methemoglobin, which can lead to the condition methemoglobinemia.National Institute for Occupational Safety and Health (NIOSH) specifies that the concentration that is immediately dangerous to life or health (IDLH value) is 1,000 ppm.

One recent example concerns the greenhouse gas (GHG) nitrogen trifluoride (NF3), a chemical that is released in some high-tech industries, including in the manufacture of many electronics. The GHG Protocol now requires NF3 to be included in GHG inventories under the Corporate Standard, Value Chain (Scope 3) Standard, and Product Standard. A new GHGP Amendment updates the existing requirements.

NF3 is used in a relatively small number of industrial processes. It is primarily produced in the manufacture of semiconductors and LCD (Liquid Crystal Display) panels, and certain types of solar panels and chemical lasers. To the extent that these processes occur in your company’s direct operations or value chain, they may need to be reflected in future inventories to ensure conformance with GHG Protocol standards.

NF3 is now considered a potent contributor to climate change and is therefore mandated to be included in national inventories under the United Nations Framework Convention on Climate Change (UNFCCC). The GHG Protocol closely aligns its reporting requirements with those of the UNFCCC to ensure consistency between national, corporate and product lifecycle inventories.

More details on NF3 and answers to frequently asked questions are on the GHG Protocol website. This document is the first in a series of new GHG Protocol publications – GHG Protocol Amendments – that alter existing requirements in the standards to reflect new scientific information or changes in business practice. We view them as an essential way to keep our standards up-to-date and to facilitate more impactful emissions-reduction efforts. Please make sure to keep an eye out for future Amendments on lease accounting and other topics.
