With the rapid development of semiconductor technology,The cleanliness requirements in the chip manufacturing process are becoming increasingly stringent。Even tiny pollutants can have a significant impact on the performance and reliability of chips。In this context,Snowflake cleaning technology as an efficient method、Environmentally friendly and precise cleaning methods,Gradually becoming the new favorite of the semiconductor industry。

one、Overview of Snowflake Cleaning Technology

Snowflake cleaningTechnology is based on high-pressure carbon dioxide(CO₂)The cleaning method,It uses high pressure to convert liquid carbon dioxide into tiny snowflake particles,And clean the surface of the object through the high-speed impact force of these particles。This cleaning method can not only effectively remove surface grease、granule、Chemical substances and other pollutants,It also has non-contact properties、Non abrasive characteristics,Avoiding surface damage that may be caused by traditional cleaning methods。

two、Snowflake cleaningAdvantages of application in the semiconductor industry

1. Efficient and precise,Improve cleanliness

In the manufacturing process of semiconductor chips,The cleanliness of the chip surface directly affects its performance and reliability。Traditional cleaning methods often struggle to completely remove tiny contaminants from the surface of chips,And the snowflake cleaning machine can rely on its high-precision cleaning ability,Deeply penetrate the microstructure and pores of the chip,Thoroughly remove residual chemicals and particles。This not only improves the quality of the chip,It also reduces the defect rate caused by pollutants。

2. Environmental protection and energy conservation,Meet the requirements of sustainable development

Snowflake cleaningTechnology uses solid carbon dioxide as a cleaning medium,During the cleaning process,Dry ice sublimates into carbon dioxide gas,Will not produce any harmful substances,No pollution to the environment。meanwhile,The cleaning machine can also recycle and reuse carbon dioxide gas,Improve energy utilization efficiency。This meets the requirements of modern industry for environmental protection and sustainable development。

3. Wide applicability,Meet diverse needs

Snowflake cleaningMachines can be customized and adjusted according to actual needs,Suitable for cleaning chips of various sizes and shapes。It can remove various pollutants,Including oils and fats、Release agent、Welding slag, etc,Suitable for chip cleaning with different materials and processes。This multifunctionality makes the snowflake cleaning machine have a wide range of application prospects in the semiconductor industry。

three、The new trend of snowflake cleaning in the semiconductor industry

1. Technological innovation and upgrading

With the continuous advancement of semiconductor technology,The technical requirements for cleaning equipment are also increasing。Snowflake cleaningTechnology is constantly innovating and upgrading,To improve cleaning efficiency and cleanliness。for example,By optimizing nozzle design and control system,Realize more precise cleaning control；Develop new cleaning media,To meet the cleaning needs of different materials and processes。

2. Intelligent Manufacturing and Automation

Intelligent manufacturing is an important trend in the development of the manufacturing industry,The semiconductor cleaning equipment industry is no exception。Snowflake cleaningDevices will be more integrated into the Internet of Things、big data、Artificial intelligence and other technologies,Realize the automation and intelligence of the production line。This can not only improve production efficiency and product quality,It can also reduce labor costs,Improve the market response speed of enterprises。

3. Localization substitution acceleration

With the continuous improvement of the quality and performance of domestic equipment,Domestic wafer fabs will be more inclined to adopt domestically produced cleaning equipment。Snowflake cleaningTechnology as an important branch of semiconductor cleaning field,It will also usher in an accelerated period of localization substitution。This will help reduce dependence on imported technology,Enhance the independent and controllable capability of the domestic semiconductor industry。
