Breakthrough in Key Materials of Semiconductor in China

With the development of electronic products, the requirement for the precision of semiconductors is increasing. Electronic grade Hydrofluoric Acid of PPT grade made in China has been adopted, which is of great significance to the development of semiconductor industry. Hydrofluoric acid, as a key material of semiconductor, acts as etchant and cleaner. The development of semiconductor materials can not be separated from Fluorine-based etching technology. With the development of electronic technology, the market requires more and more fineness of semiconductor materials, and the requirement of electronic hydrofluoric acid is more and more stringent when etching.

The original ppb level can no longer meet the market requirements, so the electronic grade hydrofluoric acid of PPT level has been adopted. China has mastered this technology. In addition to this product, we have another "lithium hexafluorophosphate" brand in hand. This is the key raw material for lithium ion batteries. With the unremitting efforts of R&D personnel in China, lithium hexafluorophosphate has achieved mass production. This has broken the original monopolized material market. While China ushered in a major turnaround in semiconductor industry, it has attracted other people's fears. In order to continue to monopolize the market share, some foreign enterprises have taken great pains to reduce their prices by a large margin. The original 1 million tons of goods have been directly reduced to 100,000 yuan a ton in an attempt to bring us down by price war. It is proud that Chinese enterprises have not been held back and withstood the pressure. Data show that the current market share of polyfluoride in fluorinated chemical industry is 30%, becoming the largest production enterprise of lithium hexafluorophosphate in China.

Without successfully replacing imported products, these foreign enterprises'market share has been squeezed out, and the products produced have also been pushed into the Korean market. With two iconic "brands" in hand, its derivatives have also touched the new energy industry.

Li Shijiang, chairman of Dofdo Chemical Co., Ltd., said in a media interview that a new material system will be introduced as the support, new energy vehicles as the Lead and lithium batteries as the core industry chain.

New materials are the links between supporting lithium batteries and connecting them. Only by actively developing these two important links, China will take the lead in the field of new energy electric vehicles in the future. In the semiconductor market, Chinese enterprises have made breakthroughs in key materials. With their excellent technical strength, they have ushered in tremendous market opportunities. With the advent of 5G era, the advantages of semiconductor materials have also successfully competed for the initiative of 5G era. The third generation semiconductor materials represented by silicon carbide can be widely used in high power and high frequency electronic devices, LED, 5G communication, automotive IGBT chip, logistics network and other microwave communication fields. It has broad prospects due to its wide band gap, high breakdown electric field, high thermal conductivity, high electron saturation drift speed and low dielectric constant.

Today, we have our own third-generation semiconductor material channel, which can guarantee unlimited material supply. In the era of 5G artificial intelligence, the third generation semiconductor materials will usher in great development and help China 5G have more initiative.

Today, China's development rate is an amazing world. Originally, because of our late start, semiconductor has been in the state of catching up with Europe, America, Japan and Korea in the past decades. But through concerted efforts, we have continuously shortened this gap and created one miracle after another, all of which are surprising.
