High performance plastics play a vital role in the semiconductor industry because of their special chemical resistance and mechanical properties. Fabs require carefully controlled environments that dampen noise and vibrations to limit static electricity Over 270 chemicals are used in the development of integrated circuits. Many of these chemicals are corrosive and require materials that will not degrade over time. This paper includes descriptions of many of the most popular plastics used in the semiconductor industry. Each description includes the special properties of the material in question along with how the material is typically used in the industry.
