In the semiconductor manufacturing process, a variety of chemicals are used, which pose potential health risks to the human body.
01
Dangerous Chemicals of Acetone
Hazard: Acetone at moderate to high concentrations can cause irritation to the nose, throat, lungs, and eyes, confusion, and even coma. Ingesting large amounts can lead to loss of consciousness and damage to the oral and skin tissues. Prolonged exposure can result in kidney, liver, and nerve damage, increase the risk of birth defects, and decrease male reproductive capacity.
Precaution: Ensure good ventilation when using acetone, and wear appropriate protective equipment, such as respirators and safety goggles.
02
Dangerous Chemicals of Arsenic
Hazard: Arsenic at low concentrations can cause nausea, vomiting, diarrhea, decreased red and white blood cell production, arrhythmia, and vascular damage. High concentrations (above 60ppm) may lead to damage to the nervous system, gastrointestinal tract, skin, and other tissues, and could be fatal. Long-term exposure can cause lung cancer and is a known human carcinogen.
Precaution: Avoid direct contact with arsenic, use appropriate personal protective equipment, and avoid working in unventilated areas.
03
Dangerous Chemicals of Arsine
Hazard: Arsine can cause headaches, weakness, dizziness, difficulty breathing, abdominal and back pain, nausea, vomiting, jaundice, peripheral neuropathy, and may damage the blood, kidneys, and liver.
Precaution: Wear protective clothing, gloves, and a mask, and ensure the work environment is well-ventilated.
04
Dangerous Chemicals of Benzene
Hazard: Benzene can damage bone marrow, reduce red blood cell production, cause anemia, excessive bleeding, immune system problems, increase the risk of infections, affect the reproductive system, and even lead to leukemia. It is a known human carcinogen.
Precaution: Avoid prolonged exposure, use ventilation systems, and wear appropriate respirators and protective equipment.
05
Dangerous Chemicals of Cadmium
Hazard: Cadmium can cause lung damage, kidney dysfunction, liver damage, skeletal defects, hypertension, reproductive toxicity, and teratogenic effects. It is reasonably expected to be a human carcinogen.
Precaution: Minimize exposure time, use protective equipment (such as gloves and masks), and undergo regular health check-ups.
06
Dangerous Chemicals of Hydrochloric Acid
Hazard: Hydrochloric acid is a highly corrosive chemical. Contact can cause severe burns to the eyes and skin. Long-term or repeated exposure may lead to skin allergies. Inhalation can cause severe respiratory irritation, coughing, burning sensations, difficulty breathing, and even coma. Ingestion can result in digestive tract burns, abdominal pain, vomiting, and even death.
Precaution: Wear protective clothing, face shields, gloves, and ensure the work area is well-ventilated.
07
Dangerous Chemicals of Lead
Hazard: Lead can damage the kidneys and immune system, lead to premature birth, low birth weight, learning disabilities, attention deficit, memory loss, anemia, weakness in the fingers, wrists, and ankles, miscarriage, and other reproductive system damage.
Precaution: Avoid lead exposure, regularly test blood lead levels, and use protective equipment.
08
Dangerous Chemicals of Methyl Chloroform
Hazard: Methyl chloroform can cause headaches, depression, poor balance, irritation of the eyes, nose, throat, and skin, and even cause arrhythmia.
Precaution: Avoid prolonged exposure, wear appropriate respirators and protective clothing.
09
Dangerous Chemicals of Toluene
Hazard: Prolonged exposure to low to moderate concentrations of toluene can cause fatigue, confusion, weakness, memory loss, nausea, and hearing loss. Short-term high-concentration inhalation can lead to brain, speech, vision, and hearing impairments, loss of muscle control, and poor balance. It is neurotoxic to children and may cause growth retardation. It is reasonably expected to be a human carcinogen.
Precaution: Use ventilation equipment, wear safety goggles and respirators, and reduce exposure.
10
Dangerous Chemicals of Trichloroethylene
Hazard: Trichloroethylene can irritate the eyes and respiratory tract. Inhalation may cause dizziness, drowsiness, and headaches. Long-term exposure can lead to speech and hearing impairments, kidney disease, blood disorders, strokes, anemia, diabetes, rashes, and more.
Precaution: Avoid inhalation, use proper ventilation facilities, and wear protective clothing.
11
In Conclusion
In the semiconductor manufacturing process, various chemicals with potential hazards to human health are used. For these substances, appropriate preventive measures are essential, including wearing personal protective equipment (such as masks, gloves, goggles), ensuring good ventilation in the work environment, and conducting regular health check-ups. Additionally, increasing workers’ awareness of these toxic substances and implementing strict management measures can effectively reduce hazards and ensure worker safety.
