Product Description
To address the stringent demands of ultrathin 4-inch wafer storage scenarios, the DOHONE 4-inch metal wafer cassette breaks through traditional design limitations by innovatively adopting a Teflon-backed stopper structure, providing professional-grade protection for wafer safe storage and transportation.
Teflon offers excellent properties such as low friction coefficient, wear resistance, and impact resistance. The Teflon-backed stopper creates a flexible buffer barrier during wafer handling. In cases of operational errors such as excessive pushing force, the stopper quickly disperses impact energy, preventing direct rigid collisions between the wafer edge and the metal cassette. This fundamentally addresses industry pain points like edge chipping and notch damage commonly seen in ultrathin wafers.
Compared to traditional metal or plastic stoppers, Teflon combines chemical stability and high-temperature resistance, making it compatible with various process conditions in semiconductor production environments without generating particle contamination, thus ensuring wafer surface cleanliness. The product is specifically customized for ultrathin 4-inch wafers, precisely matching their fragile and delicate physical characteristics. Whether for long-term static storage or frequent handling operations, it ensures safe wafer protection, providing a stable and reliable carrying solution for scenarios such as semiconductor device R&D and small-batch production.
Founded in 2003, DOHONE specializes in semiconductor chip handling and storage solutions, having delivered 3,000+ customized product solutions to industry clients, all highly favored for their precision. We are confident in our ability to assist you. Simply provide your design specifications or samples, and we will deliver a tailored solution that meets your exact needs.
