Latest Patents
Zhang's latest invention is a silicon wafer carrier that consists of a unique composition. This composition includes (a) 100 parts by weight of a polyester, (b) 5 to 100 parts by weight of a polyether ester amide, (c) 10 to 2,500 ppm of an alkaline metal, and (d) 0 to 40 parts by weight of a modified polyolefin. The carrier is designed to generate not more than 10 ppm of volatile gas when heat-treated at 150°C for 60 minutes. Additionally, it elutes not more than 10 ppm of the alkaline metal when immersed in pure water at 80°C for 120 minutes. This innovative carrier effectively suppresses the generation of volatile gas and the elution of metal, thereby preventing surface contamination of silicon wafers. It also boasts excellent permanent antistaticity, high mechanical properties, and heat resistance.
