Electronic industrial chemicals, industrial chemicals for the high-tech industry. Industry plays a key role in all manufacturing sectors.
The electronics industry makes heavy use of specialty chemicals in many processing steps. The end products of electronics industry manufacturers require high precision. Therefore, strict requirements for electronic chemicals are inevitable. Suppliers of electronic chemicals subject their chemicals to extremely strict criteria. These expenditures are called electronic levels. So what are electronic industrial chemicals and what types do they include? The following article will send you this information.
Electronic industrial chemicals
What are electronics industry chemicals?
Electronic industrial chemicals or simply electronic chemicals. This concept often refers to semiconductors and printed circuit boards (PCB). However, in reality this definition includes semiconductors, semiconductor processing chemicals and semiconductor packaging materials.
Semiconductor processing chemicals include specialty gases, wet chemicals, photoresists, thin-film metals, and CMP slurries.
Electronic industrial chemicals
There are many types of electronics industry chemicals used today. The electronics industry has the fastest growth rate, so does the electronic chemicals industry. The development of the electronics industry is constantly expanding and requires high technical skills. This is a mandatory requirement for electronic chemicals that meet production requirements. Electronic chemicals include specialty chemicals used in the manufacture of integrated circuits or silicon chips including silicon wafers, natural and specialty gases, photoresists, auxiliary chemicals, wet process chemicals , CMP slurry, metal thin films, chemicals and new materials such as copper plating.
Electronic chemicals require high precision and careful testing during production
Electronic chemical classes include:
- Heavily used gases include nitrogen, oxygen, argon, helium and hydrogen.
- Dopants gases, including arsine, phosphine, boron trifluoride, boron trifluoride and dibo-rane.
- Etchant gas: includes boron trorloride, chlorine, chlorine trifluoride, hydrogen chloride, hydrogen fluoride, nitro trifluoride, silicon tetrafluoride, sulfur hexafluoride, tetra-fluoromethane, trifluoromethane, difluoromethane, fluoromethane, hexafluoroethane, pentafluoroethane, octafluoropropane and octafluorocyclobutane.
- Chemical vapor deposition (CVD) chemicals: includes silane, dichlorosilane, trichlorosi-lane, silicon tetrachloride, disilane, tetraethylorthosilicate, silicon tetrafluoride, methyl-silane, germane, ammonia, nitrous oxide and tungsten hexafluoride.
- Wet chemicals: including acetic acid, acetone, ammonium fluoride, ammonium hydroxide, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, isopropyl alcohol, nitric acid, phosphoric acid and sulfuric acid.
With 54% of total electronic chemical consumption, silicon accounts for the largest proportion of use in the entire electronic chemical industry. Growth in wafer area revenues and prices is requiring better chemical product manufacturing. Wafer price increases for all diameter sizes are driven by the ongoing silicon shortage and rising energy costs in the process.
The four largest silicon wafer manufacturers accounted for 90.8% of the global market in 2010. The manufacturers in order of size are: Shin-Etsu Handotai, Sumitomo Mitsubishi Silicon Corporation (SUMCO), Siltronic and MEMC Electronic Materials. It is expected that the total market share of the four largest companies will increase further.
Consumption of electronic gases used in the semiconductor industry ranks second. Development statistics will increase by an average of about 6%. As semiconductor complexity increases, the number of processing steps and layers increases, such as gas phase etching and cleaning in some wet processes. About 55% of total consumption by value is accounted for by compressed air in cylinders. The remaining 45% includes silanes and derivatives, dopants and etchants, detergents, reagents.
The global electronics industrial gas chemical market for the semiconductor industry is dominated by Air Liquide, Air Products, Linde Nippon Sanso and Praxair. A variety of other companies are individual gas producers and suppliers.
Electronic chemicals for manufacturing semiconductors
Growth in consumption of IC treatment chemicals is driven by increased demand. This value has more than doubled in the past ten years. The majority of the new capacity is at the 45-180 nm nodes and the treated silicon wafer surface. Besides, more expensive chemicals are consumed by new technology industries. The increased technological efficiency provided by the semiconductor device industry results in lower material usage per silicon wafer surface area. Famous product lines are photoresists, wet chemicals, special purpose gases, CMP mud.
In 1998, about three-quarters of the world's electronic chemicals market was concentrated in the United States, Western Europe and Japan. This dominance was soon usurped by the other nations of Asia. These countries emerged as manufacturing regions within the next 10 years, accounting for 47% of the world's chemical consumption.
Specialized and increasingly improved electronic chemicals
This trend is driven by the growing global consumer electronics market. The consumer electronics manufacturing industry is growing stronger in Asia. In addition, the strategy of integrated equipment manufacturers in the US, Europe and Japan is shifting to the strategy of outsourcing less important items to factories in Taiwan and Korea. , China or Singapore. IC's largest chemical consumption region is Japan, accounting for about 25% of the total. This is followed by South Korea (18%), United States (16%), Taiwan (16%), Europe (12%), Other Asia (7%), and China (6%).
