GB/T 33140-2016 in English

1. Background and significance of standard formulation

With the rapid development of the integrated circuit industry, phosphor copper anodes are key electroplating materials, and their performance directly affects the quality and efficiency of semiconductor manufacturing. In order to standardize industry standards and ensure product quality and technical consistency, "GB/T33140-2016 Phosphor Copper Anodes for Integrated Circuits" came into being. This standard is managed by the National Technical Committee for Standardization of Nonferrous Metals, filling the gap in the field of high-purity phosphor copper materials in China.

2. Standard Framework and Main Contents

3. Technology evolution and application cases

The application of phosphor copper anode is mainly concentrated in the electroplating process in semiconductor manufacturing. With the improvement of chip integration, the requirements for material purity and grain size are becoming increasingly stringent. For example, in advanced processes, the average grain size of 150μm~450μm can effectively reduce coating defects and improve electroplating uniformity.

4. Implementation Suggestions and Future Outlook

• Both the supply and demand parties should strictly inspect and accept according to the standards to ensure product quality.
• It is recommended that enterprises establish a complete quality traceability system to achieve full-process monitoring from raw materials to finished products.
• In the future, with technological advances, phosphor copper anodes will develop towards higher purity and better grain size.
