Semiconductor manufacturing processes have extremely high requirements for the cleanliness of the production environment. Tiny particles and trace ionic contaminants can lead to a significant drop in yield. The semiconductor industry's demand for cleanroom wipers has evolved from simple wiping tools to key consumables that ensure process stability and yield.




1. Requirements for Cleanroom Wipers in Advanced Processes

  • Ultra-high cleanliness level:
Must meet Class 10 and above cleanroom standards, effectively control particle release, and comply with the strict cleanliness requirements of high-precision industries such as semiconductor manufacturing.

  • Minimal chemical elution:
Strictly control the elution of specific ions such as sodium (Na⁺) and chloride (Cl⁻), as well as Non-Volatile Residue (NVR), to prevent chemical contamination from affecting device performance.

  • Excellent physical properties:
Possess good liquid absorption capacity and contaminant adsorption efficiency; feature high strength, low particle generation, and good wear resistance to ensure that fibers do not easily fall off during repeated wiping.

  • Broad chemical compatibility:
Able to withstand high-purity solvents commonly used in semiconductor manufacturing, such as Isopropyl Alcohol (IPA), ethanol, and deionized water, while maintaining stable performance.

2. Technical Advantages of Baoshili Cleanroom Wipers

Different from ordinary cleanroom wipes, Baoshili Cleanroom Wipers are upgraded "ultra-clean" solutions specifically designed for high-tech electronics industries such as semiconductors. With superior product characteristics and innovative independent technologies, they are more suitable for the needs of advanced semiconductor processes. Their advantages are reflected in the following aspects:




  • Superior micro-contaminant control:
Operations are carried out in Class 10 cleanrooms, and ultra-pure water cleaning is used to effectively remove ionic residues; in terms of process, anti-fiber shedding technology is adopted, combined with hot cutting, laser, and ultrasonic edge-sealing technologies to prevent edge debris.

  • Precise static voltage control:
Baoshili anti-static wipes are woven from anti-static fibers and polyester fibers, effectively preventing breakdown of nanoscale circuits and thus ensuring device yield.

  • Excellent liquid absorption performance and physical structure:
Adopt continuous weaving technology, using 100% polyester fibers or microfibers, making the surface of the cleanroom wiper soft to avoid damage to the surface of wafers and devices. At the same time, it has strong water absorption capacity, enabling effective cleaning of devices.

3. Applications of Cleanroom Wipers in the Semiconductor Industry

Currently, Baoshili has become a qualified supplier to many world-leading wafer foundries. The products are widely used in key process links such as advanced logic chip and memory chip manufacturing lines, as well as compound semiconductor production. Their performance and reliability have been verified by customers over the long term. Their application scope includes:

  • Precision component cleaning:
In the semiconductor manufacturing process, cleanroom wipers are used to remove tiny particles, organic residues, and metal ions from the surface of precision components, ensuring their surface cleanliness.

  • Equipment cleaning:
Clean dust, oil stains, and metal debris inside semiconductor production equipment to prevent contaminants generated during equipment operation from spreading to the wafer surface and affecting product quality.

  • Cleanroom environment maintenance:
Regularly wipe surfaces such as cleanroom walls, floors, and workbenches to maintain the high cleanliness of the cleanroom, reduce the concentration of suspended particles in the air, and provide a stable dust-free environment for semiconductor manufacturing.

Baoshili is committed to providing high-performance and highly reliable cleanroom wiper products for the semiconductor industry. We will continue to invest in R&D and production, strictly adhere to quality standards to meet the evolving cleanliness needs of advanced processes, and become a trustworthy partner for customers.
