Driving Innovation in Semiconductor Manufacturing

At Piedmont Plastics, we understand that the semiconductor industry operates incredibly precisely, demanding the utmost precision and cleanliness. Any contamination in the manufacturing process can introduce significant defects in the final products, necessitating strict cleanroom environments.

The production of semiconductors also exposes materials and equipment to extreme temperatures and harsh chemicals used in etching and cleaning processes. This challenging environment requires specialized materials that can withstand these conditions without deteriorating, ensuring the reliability and functionality of the semiconductor devices produced.

Our advanced engineering solutions and high-performance materials are designed to meet these rigorous standards of durability and resistance, supporting the critical needs of the semiconductor industry.

Role of Plastics in Semiconductor Fabrication

In the semiconductor industry, high-performance plastics are gaining popularity over traditional materials like ceramics or quartz. Their flexibility and, most importantly, their cost-effectiveness make them a preferred choice. Plastics such as HDPE, polycarbonate, and polypropylene offer unique advantages, including lower cost, ease of machining, and excellent resistance to the harsh chemicals used in semiconductor manufacturing.

For instance, HDPE is widely used for parts that require strong resistance to acids and contaminants. It also proves its versatility by being ideal for protective surfaces and containers within cleanrooms.

Polycarbonate is utilized not just for its strength and impact resistance but also to demonstrate its adaptability in making protective covers and structural components of semiconductor machinery. In contrast, polypropylene is not just preferred for its chemical resistance, but it also shows its flexibility in wet benches and chemical handling systems.
