Tetramethylsilane TMS can be used in the electronics industry, and there is a large market space for high-purity products

Tetramethylsilane, referred to as TMS, the chemical formula is C4H12Si, also known as tetramethylsilane, and its appearance is a colorless liquid. Tetramethylsilane is insoluble in water and soluble in most organic solvents. It has stable chemical properties and good thermal stability and will not be decomposed by concentrated sulfuric acid or strong alkali. Tetramethylsilane is volatile and flammable. It can burn when exposed to open flames, high heat, and oxidants. There is a risk of explosion in a closed environment. The decomposition products are silicon oxide, carbon monoxide and carbon dioxide. When exposed to ultraviolet rays, chloromethyltrimethylsilane can be generated.

Tetramethylsilane can be used in nuclear magnetic resonance reference materials, reagents, solvents, aviation fuel and other fields. In NMR Pop analysis, due to its low electronegativity and little impact on hydrogen atoms, it can give strong signals and absorption peaks. Tetramethylsilane can be used as a reference material to measure the chemical shifts of hydrogen, carbon, and silicon. , is an ideal standard reagent for NMR Pop analysis. Tetramethylsilane can also be used as aviation fuel due to its flammable properties.

According to the “Tetramethylsilane (TMS) Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” released by the Industrial Research CenterIt shows that tetramethylsilane is a silicon-based gas. High-purity tetramethylsilane with high purity and low impurity content is an electronic gas and can be used in the semiconductor industry. Tetramethylsilane can be used as a precursor gas to prepare thin films using chemical vapor deposition (CVD). It can be used in fields such as etching hard masks, depositing carbon-doped silicon-containing films, and depositing silicon carbide thin films. As the scale of the electronics industry continues to expand, the demand for electronic gases in the semiconductor field continues to rise, and the tetramethylsilane market continues to grow.

In 2020, the global electronic gas market size was approximately US$5.92 billion. The scale of the global electronics industry is still expanding, existing product updates are accelerating, new products are constantly being developed, and the development momentum of the semiconductor market is still strong, which will continue to drive the demand for electronic gases. It is expected that the global electronic gas market will grow at a compound annual growth rate of approximately 6.6% from 2020 to 2025, and the market size will reach approximately US$8.14 billion by 2025. As a kind of electron gas, tetramethylsilane has good development space.

Globally, tetramethylsilane production companies mainly include Air Liquide of France, Versum Materials of the United States, Dupont of the United States, Gelest of the United States, etc.; in the Chinese market, tetramethylsilane production companies mainly include Shanghai Merrill Chemical Technology Co., Ltd., Jiangsu Kaimei Electronic Materials Co., Ltd., etc. However, among my country’s tetramethylsilane production companies, the number of companies that can produce high-purity electronic grade tetramethylsilane products is small, and there is still much room for optimization of the industry structure in the future.

Industry analysts said that there are many types of electronic gas products, and a single product usually has a small amount, but it is highly indispensable. . Compared with high-purity ammonia, carbon tetrafluoride, hydrogen chloride, sulfur hexafluoride, etc., the annual demand for tetramethylsilane is small and the market size is small. However, my country is the world’s largest producer of electronic products. The scale of the semiconductor industry continues to expand. The market demand for tetramethylsilane will continue to grow in the future. Therefore, my country’s electronic-grade tetramethylsilane production strength needs to be enhanced.
