ISO 5 level (formerly Class 100) belongs to an extremely high level of cleanliness. It has extremely strict control over the concentration of particles in the air with a size of ≥ 0.5 μm. It is suitable for high-precision fields that have zero tolerance for dust and microbial contamination. When combined with a rapid rolling-type air shower room, it can not only meet the extremely high cleanliness requirements but also adapt to the frequent and rapid turnover of goods. The core application industries and specific scenarios are as follows:
1. Semiconductor and microelectronics industry (the most typical field with ISO 5-level cleanliness requirements)
This industry is the most typical field with ISO 5-level cleanliness requirements. Even tiny particles can cause the failure of chips and wafers. High-cleanliness air shower rooms must be used to achieve dust removal and clean isolation of materials.
Core scenarios: Core process areas such as lithography, etching, film deposition, and ion implantation in wafer manufacturing plants, used for transporting wafer boxes, photomask plates, high-purity chemical reagents, and precision manufacturing components; Clean areas for packaging and testing of high-end chips and storage chips, transporting chip products, packaging substrates, and precision testing fixtures; Core process areas for the mass production and pilot production of Micro-LED and Mini-LED chips.
2. Biopharmaceutical and high-end medical device industry
It needs to meet strict requirements for sterility, low particle count, and microbial control, complying with GMP and biosafety standards. ISO 5-level air shower rooms are used to block external pollution and ensure that the production environment meets standards.
Core scenarios: Clean areas for the production of biological products such as vaccines, sterile powder injections / water injections, monoclonal antibodies, recombinant proteins, etc., and sterile preparations; Production, assembly, and sterilization after transportation of implantable medical devices such as heart stents, artificial joints, implantable pacemakers, and artificial crystals; P3 and P4-level biosafety laboratories, used for transporting experimental consumables, standard samples, and compliant experimental waste; Clean laboratories for cell and gene therapy (CGT) such as cell culture, formulation preparation.
3. Precision optics and optoelectronics industry
Tiny particles on the surface of optical components can directly affect the light transmittance, imaging accuracy, and performance of the products. The cleanliness level requirements are extremely high.
Core scenarios: Processing, coating, and inspection areas for lenses for lithography, high-precision industrial lenses, prisms, optical filters; Production and assembly workshops for infrared detectors, high-energy laser components, and core optical components of laser radar; Clean areas for the assembly of high-magnification microscopes and medical optical diagnostic equipment.
4. Aerospace and high-precision manufacturing industry
The precision requirements of core components in aerospace and aviation are extremely high. Particle contamination can cause component failures, affect the service life of equipment, and even cause major safety hazards. ISO 5-level environment is required for guarantee.
Core scenarios: Production and assembly clean areas for satellite precision components, aerospace sensors, inertial navigation system components, and precision components of rocket engines; Precision machining and inspection workshops for aerospace engine blades, high-precision aerospace bearings, and servo motors; Production and storage areas for high-end radar components, precision guidance components, and military special chips in the military field.
5. Photovoltaic and advanced display manufacturing industry
The ordinary processes in the photovoltaic and display industries are mostly adapted to 10,000-level or 100,000-level cleanliness, but their core and high-end processes must use ISO 5-level environment to avoid particle contamination affecting the photoelectric conversion efficiency and display effect of products.
Core scenarios: Core process areas such as HJT, IBC, and TopCon high-efficiency photovoltaic cells, transporting silicon wafers, battery cells, and high-purity targets; Core process areas for vapor deposition, lithography, and packaging of OLED and flexible screens, transporting glass substrates, organic light-emitting materials, and precision display modules.
6. Research and high-end new materials industry
For cutting-edge research and the preparation of nanoscale materials, there are extreme requirements for environmental cleanliness. ISO 5-level air shower rooms are required to ensure that experiments and production are not contaminated by external factors. Core scenario: Laboratory and pilot production lines for the preparation of nanomaterials, development of quantum devices, and high-end superconducting materials; storage and transportation areas for high-purity chemicals and electronic special gases used in semiconductors and biomedicine.
Key adaptation features
ISO 5 level rapid rolling-style air shower room, which requires a H14 level high-efficiency filter to ensure that the outlet particles meet standards. At the same time, with the advantages of rapid opening and closing of the rolling door and high sealing performance, it reduces air convection between the clean area and non-clean area, eliminates cross-contamination, and perfectly meets the dual requirements of these industries of “high cleanliness + high frequency goods turnover”.
