1、 Semiconductor industry: the guardian of process stability

The precision requirements for gas flow control in semiconductor manufacturing are almost stringent, and any small deviation may lead to a decrease in wafer yield. Qingdao Xinsheng's MFC products are deeply involved in core processes such as chemical vapor deposition (CVD), physical vapor deposition (PVD), etching, and ion implantation

• CVD processWhen depositing silicon dioxide thin films, it is necessary to accurately ratio the flow rates of silane and oxygen. Qingdao Xinsheng MFC ensures stable gas ratio and avoids uneven film thickness or abnormal electrical performance through real-time monitoring and dynamic adjustment.

• etching processThe flow control of fluorinated gases (such as SF ₆) directly affects the etching depth and pattern accuracy. The product quickly responds to changes in process parameters, ensuring the controllability of the etching process.

• ion implantationThe flow stability of the doped gas determines the conductivity of the chip. Qingdao Xinsheng MFC is designed with low leakage rate to prevent gas leakage from contaminating equipment and extend its service life.

2、 Photovoltaic industry: an invisible driving force for efficiency improvement

Photovoltaic manufacturing, from silicon wafer deposition to module packaging, relies on precise control of gas flow rate. Qingdao Xinsheng MFC products cover key links in the entire industry chain:

• PECVD (Plasma Enhanced Chemical Vapor Deposition)By accurately proportioning silane and ammonia, the uniformity and photoelectric performance of the film are optimized to improve the conversion efficiency of the battery cells.

• Atmosphere control of single crystal furnaceStabilize the vacuum inside the furnace in an inert gas environment (such as nitrogen or helium) to ensure high purity and low defect rate of single crystal silicon growth.

• Welding and packagingDuring the component welding process, control the flow rate of nitrogen or argon to prevent material oxidation; The packaging process is protected by inert gas to extend the service life of the battery board.

3、 Biological fermentation industry: the "core engine" of process optimization

During the process of biological fermentation, the growth environment of microorganisms is highly sensitive to gas components. Qingdao Xinsheng MFC products achieve process optimization through the following methods:

• Oxygen and carbon dioxide regulationIn antibiotic and amino acid fermentation, precise control of oxygen flow promotes microbial metabolism, while regulating carbon dioxide emissions to maintain pressure balance inside the tank and improve product purity.

• Anaerobic environment simulationIn anaerobic processes such as lactic acid bacteria fermentation, oxygen is eliminated through nitrogen flow control to protect sensitive enzyme activity and ensure the stability of the fermentation process.

• Real time monitoring and abnormal warningCompare the set flow rate with the actual value, promptly detect tank leaks or metabolic abnormalities, and provide data support for process adjustments.

4、 Instrumentation industry: the 'precise ruler' for scientific research experiments

In analytical instruments such as gas chromatographs and mass spectrometers, the stability of gas flow rate directly affects the detection results. Qingdao Xinsheng MFC products have become an ideal choice for scientific research experiments due to the following characteristics:

• Carrier gas controlIn gas chromatography analysis, precise control of the flow rate of carrier gases such as helium and nitrogen ensures the separation efficiency and repeatability of the sample in the chromatographic column.

• Ionizing gas regulationDuring the electron impact ionization (EI) process of a mass spectrometer, stabilizing the ionized gas flow rate enhances signal strength and quality resolution.

• environment simulationIn the development of biosensors, simulating different gas concentration environments provides reliable data for sensor calibration.

5、 The food and medical industry: a "dual guarantee" of safety and quality

In fields such as food packaging and medical equipment, precise control of gas flow is directly related to product safety and user experience. Qingdao Xinsheng MFC products demonstrate their technological value through the following applications:

• food packagingIn nitrogen filled packaging of potato chips, nuts, etc., high-purity nitrogen gas is quickly filled to control the residual oxygen rate at an extremely low level and extend the shelf life; In the modified atmosphere packaging of fruits and vegetables, the proportion of oxygen and carbon dioxide is adjusted to inhibit respiration and maintain freshness.

• medical equipmentIn the anesthesia machine, precise control of oxygen and nitrous oxide (nitrous oxide) flow rate ensures safe anesthesia dosage for patients; In a ventilator, oxygen supply is dynamically adjusted based on the patient's respiratory parameters to maintain stable blood oxygen saturation.

• Fermented food productionIn the fermentation of beer and yogurt, the oxygen flow curve is programmed to optimize microbial metabolic pathways and improve flavor quality.
