Hexachlorodisilane HCDS has high technical barriers and great market potential in the semiconductor field

Hexachlorodisilane, the molecular formula is Cl6Si2, abbreviated as HCDS, also known as hexachlorodisilane and disilicone hexachloride. Hexachlorodisilane appears as a colorless and transparent liquid with stable performance and low volatility. It will react violently when exposed to water and is insoluble in alcohols and strong alkali. Hexachlorodisilane belongs to chlorosilanes and is one of the products with higher application value among oligochlorosilanes. It is an organic intermediate that can be used to prepare disilane and other products, and can also be used to deposit thin films. It is important in the semiconductor and solar energy industries. downstream market.

The purity of electronic grade hexachlorodisilane needs to be above 99.9%. The purity between 99% and 99.9% belongs to low purity hexachlorodisilane. The purity of 99.9% to 99.999% belongs to standard purity hexachlorodisilane. The purity reaches 99.999% – 99.99999% is high purity hexachlorodisilane. In comparison, the semiconductor industry has higher requirements for the purity of hexachlorodisilane, while the solar energy industry has relatively low requirements. Hexachlorodisilane has good low-temperature properties and can replace silane and dichlorosilane. Chemical vapor deposition (CVD) and atomic layer deposition (ALD) are used to prepare high-quality silicon oxide films and silicon nitride films. In addition, it can also be used In the field of photochemical optical fiber, siloxane precursor and other product preparation fields.

According to the “2021-2025 Hexachlorodisilane (HCDS) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center Shows that global demand for hexachlorodisilane continues to grow, benefiting from the continued expansion of the semiconductor and solar industries. In 2019, the global hexachlorodisilane market size was approximately 960 million yuan; it is expected that the global hexachlorodisilane market will grow at an average annual compound growth rate of approximately 4.2% from 2020 to 2025, and the market size will reach 1.23 billion yuan by 2025 Yuan or so. In 2019, the semiconductor industry was the largest downstream market for hexachlorodisilane, with demand accounting for about 78%.

Globally, the main manufacturers of hexachlorodisilane include Dow Corning of the United States, Evonik of Germany, Air Liquide of France, Toagosei of Japan, Hansol of South Korea, etc., with leading enterprise shares It accounts for a large proportion and the global market concentration is high. The price of electronic grade hexachlorodisilane is high. In order to meet the needs of the domestic semiconductor and solar industry, my country’s hexachlorodisilane production capacity has been continuously improved. The main manufacturers include Luoyang China Silicon, Yangzhou Sanyou, Mairel, Jinjinle, etc.

my country already has the capacity to mass-produce standard-purity hexachlorodisilane and can provide supporting services for the solar industry. High-purity hexachlorodisilane used in the semiconductor field has high technical barriers. my country’s production capacity is weak, and market demand mainly relies on imports.

Industry analysts said that my country’s semiconductor industry is developing rapidly and is currently the world’s largest semiconductor market. The government’s support for the development of the semiconductor industry Large, hexachlorodisilane plays an important role in the field of thin film deposition in the semiconductor industry and has broad market prospects in the future. Against this background, my country’s high-purity hexachlorodisilane market needs to accelerate the pace of import substitution. Companies that take the lead in mass production of high-purity hexachlorodisilane and are recognized by downstream customers have great potential for future development.
