Decomposition of sf 6 in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of insulating gas. The decomposition fraction of Sulfr hexafluoride [etagaz sf6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/Sulfr hexafluoride ratio in an SiO2 reactor.Get price

Gas detection systems from Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.Get price

The Carbon Brief Profile: South Korea

PoliticsParis Pledge‘Green Growth’ Policies‘New and Renewable’ EnergyNuclearCoalTransportIndustryImpacts and AdaptationSince the hostilities of the Korean War ended in 1953, the Republic of Korea – one of the “four Asian tigers” – has grown from a developing country into a significant economic power with the 12th-highestGDP in the world. In particular, it has become known as a major exporter and an industrial leader in many sectors, including electronics, cars, shipbuilding and steel. Following decades of authoritarian rule, South Korea held its first free parliamentary election in 1988. Its two major political parties are the conservative United Future Party and the ruling liberal Democratic Party, with Moon Jae-inserving as the nation’s current Democratic president. The next legislative election, in which all 300 members of the country’s national assembly will be chosen, is set to take place on 15 April. Not only will this election be the first since the Korean voting age was lowered from 19 to 18, it will also see some politicians elected via proportional representation for the first time, potent...Get price
