The term electronic grade chemicals is used to refer to chemicals used in electronic industry, particularly in semi-conductor/ micro processor fabrication or simply “fab”. Solvents are widely used in electronics for cleansing, stripping, degreasing, operations, encapsulation. Gases are found in ion implanters, diffusion furnaces, expitaxial reactors, etc. Gases are also used in quality control to detect flaws in electronic components. Dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) in order to alter the electrical properties or the optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the material. These materials are very commonly either crystals of a semiconductor (silicon, germanium, etc.), for use in solid-state electronics or else transparent crystals that are used to make lasers of various types. Electronic specialty gases (ESGs) used in the manufacture of semi-conductor and electronic components are often hazardous due to their inherent physical properties and chemical and biological reactivity. Chemicals such as Silicon, Copper, gold & Aluminium are used in semiconductor manufacturing. Boron,is a semi-metallic element used as a dopant in semiconductor devices. Aqueous chemical cleaning is an example of an effective parts washing method. Its cleaners are generally environmentally friendly because the constituents are typically less toxic than solvents and do not contain ozone-depleting substances (ODSs). The electronic-grade hydrofluoric acid of China is limited in terms of both capacity and output by reason of technical barriers. Since 2009, two 1,000-ton-above projects have put into production successively in China, referring to 6,000 tons/year electronic-grade hydrofluoric acid project of Zhejiang Kaiheng Electronic Materials Co., Ltd and 3,000 tons/year electronic-grade hydrofluoric acid project of Fujian Shaowu Yongfei Chemical Industry Co., Ltd. The electronic industry worldwide stimulated the growing demand for electronic-grade hydrofluoric acid.
