Introduction: In recent years, with the rapid rise of new energy vehicles and artificial intelligence, the demand for semiconductors has continued to grow. The rapid development of intelligent technology has accelerated the transition of semiconductor size from microelectronic level to atomic level. Third generation semiconductors usher in a new era of high-quality development! At the same time, the manufacturing process is also more complex. What products from Hikelok can help with semiconductor development? Let's learn more together!
Emerging technologies such as artificial intelligence and big data are key driving forces for development, leading to the need to package greater performance into smaller chips. This means that the manufacturing process will become more complex, requiring faster response capabilities and higher component reliability to ensure high-precision chemical transportation will become a top priority.
Due to the precision and complexity of semiconductor chip manufacturing, whether it is valves for precise gas control or pipeline connectors for carrying electronic gases, they should comply with relevant ASTM and SEMI industry standards and possess the following characteristics:
1. Stainless steel raw materials must be refined using ultra-high purity VAR or VIM-VAR to ensure the requirement of ultra-high purity from the source;
2. The inner surface in contact with the medium needs to undergo processes such as electrochemical polishing and passivation to achieve ultra cleanliness while improving the corrosion resistance of the product;
3. Stainless steel and plastic products must meet relevant ASTM and SEMI industry standards such as internal humidity analysis control, total organic carbon (TOC) analysis control, and ion pollution composition control.
Hikelok's ultra-high purity series products meet the requirements of the semiconductor industry for fluid components and comply with ASTM and SEMI industry standards, including raw material selection, high standard processing technology, and assembly testing in a 100 level dust-free workshop. The product types include ultra-high purity pressure reducing valves, ultra-high purity diaphragm valves, ultra-high purity bellows sealed valves, integrated panels, ultra-high purity fittings, and EP tubing. Multiple size types are available, and customization can be made according to on-site proprietary installation requirements.
Adopting a metal to metal sealing form to achieve reliable sealing of products within the vacuum and positive pressure range. After the standard treatment process, the average roughness of the surface polishing of the ultra-high purity joint in contact with the medium can meet 10% μ In. (0.25 μ m) Ra; After ultra-high purity process treatment, the average roughness of the surface polished in contact with the medium can meet 5 μ In. (0.13 μ m) Ra. The ultra-high purity joint nut is designed with a leak detection hole, which facilitates leak detection. The nut threads are treated with silver plating process to reduce thread wear and reduce the risk of thread engagement during installation.
