The centrifugal two-medium gas combination compressor independently developed by us has been successfully tested and put into use in a global leading integrated circuit manufacturing enterprise in Jiangsu Province. All parameters meet the design requirements and are well received by users.
As we all know, among the eight core materials in the semiconductor industry, electronic gas is the main raw material next to silicon, accounting for 13.5% of the value of semiconductor wafer manufacturing materials. Electronic gas is widely used in the manufacturing process of electronic products in ion implantation, etching, gas phase, deposition, doping and other processes, known as integrated circuits, liquid crystal panels, LED and photovoltaic materials such as the "food" and "source". The performance of electronic semiconductor devices is closely related to the quality of electronic gas, and high purity/ultra-high purity nitrogen is one of the most important members of electronic gas, and it is an indispensable raw gas and process gas in the semiconductor production process, such as inert protection, carrier gas, special gas, pipeline purge exhaust, dilution, plasma injection, etc. The centrifugal double medium gas compressor is the core equipment of high purity nitrogen production technology. The market for this type of compressor has long been dominated by American companies.
The unit successfully put into operation this time is the first set of this type of compressor manufactured by our company with fully independent intellectual property rights. It is used in the nitrogen production system of one of the world's top 500 international well-known gas companies. This is also the first time for this company to cooperate with a Chinese compressor manufacturer. The success of this operation greatly enhanced the market competitiveness of the company's high purity nitrogen preparation system. This is the result of four years of joint efforts by both sides.
At the same time, the commissioning work of two sets of this type of compressor used in the domestic high purity nitrogen preparation system has been completed, and the parameters meet the design requirements, or even some parameters exceed the design requirements.
Over the past two decades, we have continued to invest heavily in core technologies, and gradually built up certain technological advantages in screw, turbine, reciprocating and other types of compressors, expanders, vacuum pumps and many other fields. Under the background of the increasing demand for "localization", this technological advantage enables our Chinese users not to sacrifice the quality of required equipment due to "localization", but to obtain more reliable product quality and lower energy consumption after "localization". And for our international users, they find that the Chinese equipment represented by us has brought them greater benefits. The successful operation of the centrifugal two-medium gas combination compressor is just a small example of the above words.
