With the rapid development of technology,The semiconductor manufacturing industry has increasingly high requirements for quality and efficiency。In the field of micrometer to nanometer scale,Minor pollutants seriously affect chip performance。therefore,Efficient and precise cleaning equipment is crucial。Snowflake cleaning machineWith unique cleaning mechanism and deep cleaning ability,Plays an irreplaceable key role in semiconductor manufacturing。

one、Working principle of snowflake cleaning machine

Snowflake cleaning machine,Also known as dry ice cleaning machine,It is a type based on carbon dioxide(CO₂)Cleaning equipment。It uses high pressure to convert liquid carbon dioxide into tiny snowflake particles,When these particles collide with the surface of semiconductor materials at high speed,Capable of generating strong physical impact force,Simultaneously incorporating the low-temperature effect,Effectively remove pollutants from surfaces and microstructures。This non-contact cleaning method,Avoiding scratches and damages that may arise from traditional mechanical cleaning,Ensured thorough and efficient cleaning。

two、Snowflake cleaning machineAdvantages of

Micro level and even nano level cleaning:Snowflake cleaning machineThe snowflake particles are extremely small in size,Capable of penetrating into the tiny gaps and depressions on the surface of the wafer,Thoroughly remove pollutants at the micrometer or even nanometer level,Like particles、organic compound、Metal ions, etc。This high-precision cleaning capability,Provided reliable assurance for semiconductor manufacturing processes。

No residue、Pollution-free:Snowflake cleaning machineThe cleaning medium used is liquid carbon dioxide,Non toxic and harmless,And no harmful waste liquid or gas is generated during the cleaning process。meanwhile,The cleaned carbon dioxide can be recycled through a recovery system for reuse,Reduced operating costs,Sustainable utilization of resources has been achieved。

Protect the surface of the material:Due to the use of non-contact cleaning method,Snowflake cleaning machineWhile removing pollutants,Avoiding mechanical damage and chemical corrosion to the surface of wafers or other semiconductor materials。This is particularly important for fragile chips and precise packaging structures in semiconductor manufacturing,Ensure the integrity and reliability of the product。
