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.
