Research on semiconductor Special gas industry
Globally, the size of the global specialty gas market is expected to reach us $46.9 billion in 2019, and the CAGR for 2014-2019 is 7.95%. Within China, the size of China's electronic gas market reached 12.16 billion yuan in 2018, an increase of 11.2 percent over the previous year, and the CAGR from 2013 to 2018 reached 13.3 percent.
Gas assets are favored by capital. Among them, the valuation center of special gas assets has increased from 50 times PE in the first half of 2019 to nearly 100 times PE on average at present, and the valuation center of empty assets has increased from less than 20 times PE in the first half of 2019 to more than 30 times at present.
Semiconductor chip manufacturing
Gases: the "blood" of industry: Special gases are important branches of industrial gases, among which electronic semiconductor is the important market of special gases.
Semiconductor electronic gas is used in deposition, photolithography, etching, heat treatment, doping and other aspects of wafer manufacturing. The main gas categories are fluorocarbon (mainly etching and cleaning), elemental (dilution, insulation and oxidation), doped (arsenane, phosphane, etc.), lithography (inert gas mixture), CVD (silane, germanium, etc.), etc.
