Cleanliness Requirements & Contaminants

Electronics cleanrooms generally require cleanliness of Class 100,000 or higher, calculated based on the number of 0.5 μm particles per cubic meter of air. According to cleanliness levels, they are divided into:

  • Class 100 (< 3.5 particles/m³)
  • Class 1000 (< 35 particles/m³)
  • Class 10,000 (< 350 particles/m³)
  • Class 100,000 (< 3500 particles/m³)

During integrated circuit (electronics) production, major contaminants include particulate impurities, inorganic ions, organic substances, microorganisms, and gaseous impurities. In a broader sense, unsuitable temperature, humidity, illumination, excessive static electricity, electromagnetic noise, airborne noise, and micro‑vibrations are also special contaminants.

When the amount of particulate impurities, inorganic ions, organic substances, microorganisms, and gaseous impurities exceeds a certain limit, they can cause surface scratches, pattern breaks, short circuits, pinholes, peeling, etc., leading to circuit leakage and abnormal electrical characteristics. Mild cases affect circuit performance and service life; severe cases can lead to product scrapping. Unsuitable temperature, humidity, illumination, excessive static electricity, vibration, and noise not only affect the processing accuracy and service life of equipment but also impact operators' mood, thereby affecting product quality, production efficiency, and yield. Contamination‑related failures can account for up to 60% of product failures.
