Toxic compounds are still in use because of their exceptional conductive properties, which may be challenging to top without copious research. The safety of semiconductor manufacturing employees is a top priority. Still, these facilities handle toxic materials that can pose a hazard to human health.
Worker safety is essential in manufacturing. Unfortunately, many microelectronics manufacturing processes involve toxic chemical elements that can pose health hazards. Semiconductor manufacturing processes with corresponding toxic chemicals. Image used courtesy of EPA What risks exist, and how are personnel working to mitigate them?
Semiconductor facilities utilize multiple liquids and solvents— acidic, alkaline, or otherwise—that can be as hard on human physiology as they are on the materials they treat. Aside from being caustic, many commonly-used chemicals are known human carcinogens.
Some examples that can carry high risk are toluene, acetone, methylene chloride, xylene, chloroform, and isopropyl alcohol. Others—like glycol ethers—may even cause reproductive harm. Often, workers can accidentally absorb these substances through direct skin contact; however, direct contact isn't the only way to be affected.
