Electronic chemicals, also known as electronic chemical materials, refer to fine chemical materials that are specifically designed for the electronic industry, ie integrated circuits, electronic components, printed circuit boards, industrial and consumer machine production and packaging Chemicals and materials. Electronic chemicals are integrated disciplines with multiple disciplines such as chemistry, chemical engineering, materials science, and electronic engineering.

Electronic chemical products and technologies are very extensive. Products can be divided into microelectronic chemicals, optoelectronic chemicals, display chemicals, printed circuit board chemicals, surface assembly chemicals,

Battery chemicals and other several categories.

Electronic chemicals can be divided into more than ten categories according to different application fields. They typically include: microfabricated photoresists, wet electronic chemicals, electronic specialty gases, electronic packaging materials, polishing polishing materials for silicon wafers, electronic chemicals for printed circuit boards, electronic molding materials, inorganic electronic chemicals, Hybrid circuit chemicals, capacitor materials, rare earth compounds, electrical coatings, conductive polymers and other electronic and electrical chemicals, battery materials, flat panel display industry supporting electronic chemicals. The number of electronic chemicals involved exceeds 16,000, accounting for about 65% of the total number of electronic materials. Electronic chemicals can be divided into microelectronics chemical materials (used in integrated circuits and discrete devices), chemical materials for printed circuit board surface treatment and assembly technologies, and chemical materials for display devices.

Electronic chemicals upstream are basic chemical products. Basic chemical products have an important influence on the quality and production costs of electronic chemicals. The downstream of electronic chemicals is the electronic information industry (information and telecommunications, consumer electronics, home appliances, automotive electronics, energy-saving lighting (LED, etc.), flat panel displays, solar cells, industrial control, aerospace, military and other fields), electronic information industry To a certain extent, it affects and determines the development of electronic chemicals. Therefore, electronic chemicals have become one of the key materials for the development of the electronics industry in the world.

1.1.2 The importance of electronic chemicals in the development of electronic information industry   With the continuous development of technological innovation, the field of application of electronic chemicals is also expanding, and has penetrated into various fields of national economy and national defense construction. Electronic chemicals, to a certain extent, determine or influence the development and progress of the downstream and terminal industries, and have important implications for the upgrading of domestic industrial structure, national economy, and national defense construction.

At present, the number of electronic chemicals has reached tens of thousands, with high quality requirements, less dosage, high requirements for the cleanliness of production and use of the environment, and product replacement and replacement. "Generation materials, generation products" and advanced materials can produce advanced products. With the advent of a new generation of electronic technologies, there will be a new generation of electronic chemicals.

The development of electronic technology can not be separated from the supporting electronic chemicals. Taking electronic chemicals used in the microelectronics industry as an example, it is a microelectronic micromachining technology that is a key material in the manufacturing process of integrated circuits and discrete devices, mainly including the wet electronic chemicals (also called process chemicals) and electronics used in the previous processes. Special gas and electronic plastic materials used in post process. The quality of these materials directly affects the performance and quality of electronic products, especially wet electronic chemicals, photoresists and electronic specialty gases are the bottlenecks restricting the development of microelectronics micro-processing technology. And with the rapid development of electronic technology, higher and higher requirements have been put forward for these materials. It can be said that without the development of microelectronics chemicals, there will be no rapid development of the modern electronics industry. These microelectronic chemicals play an irreplaceable role in the development of electronic technology and are the cornerstone of the development of modern electronic technology.

According to the latest statistical data on global electronic chemical consumption, the Asia-Pacific region, especially China, has become the leading market for the global electronics industry and its chemicals. Chemical companies including Dow, Honeywell, Mitsubishi Chemical, and BASF competed to focus their electronic chemicals business in the Asia Pacific region. The domestic electronic chemicals industry is in a period of rapid development. It is expected that by 2015, the market capacity will reach 40 billion to 45 billion yuan, with an average annual growth rate of more than 15%.

In 2015, the global wet electronic chemicals market capacity was approximately 20.8 billion yuan, and it is expected to maintain a growth rate of 7% to 8% in the next few years. The huge market demand has provided opportunities for China's wet electronic chemicals industry. Since the mid-1990s, the wet electronic chemicals industry in China has developed rapidly and has accounted for nearly 30% of the Asian market. In 2013, the market sales totaled 2.4 billion yuan, and it is expected to reach 5 billion to 6 billion yuan in 2015. China is already the second largest integrated circuit market in the world. It is estimated that the total annual amount of wet chemical used in integrated circuits in 2015 is estimated at 162,000 tons. With the continuous development of China's integrated circuit and optoelectronics industry, its demand for wet electronic chemicals will continue to rise.
