Used Applied Materials Semiconductor Electroplating System Nokota™ ECD

The Nokota™ ECD is a 300mm wafer-level electrochemical deposition (electroplating) system from Applied Materials. Part of the company’s electroplating product line, it primarily serves advanced packaging and back-end-of-line (BEOL) copper interconnect applications, while also covering certain front-end-of-line (FEOL) copper interconnect processes.

Process Focus: The system utilizes electroplating to deposit metal layers—most notably copper. Typical applications include under-bump metallization (UBM), copper pillars, redistribution layers (RDL), through-silicon via (TSV) filling, and copper interconnects for wafer-level packaging. It addresses challenges such as achieving uniform film thickness for micron-scale metal interconnects and ensuring defect-free filling of high-aspect-ratio structures—a distinct process category from the atomic-level precision offered by ALD/CVD technologies used in front-end manufacturing.

Design Priorities: The Nokota ECD emphasizes film thickness uniformity, high-quality filling, and repeatability for high-volume manufacturing. It features precision plating cells and advanced flow-field control, with optimizations specifically designed to mitigate wafer-edge effects. The system supports automated wafer handling and recipe management, meeting the throughput and stability requirements of high-volume production lines. Its platform architecture allows for flexible switching between various packaging-related plating recipes, enabling production lines to accommodate a diverse range of packaging requirements.

Market Positioning: The Nokota competes in the advanced packaging electroplating space alongside systems like the RAIDER Edge ECD and the ASMPT Stratus P300/P500; it is classified as electroplating equipment rather than a general thin-film deposition tool. Within the broader process chain, it complements Applied Materials’ own front-end deposition equipment, establishing a workflow that spans from front-end film formation to back-end electroplated interconnects.

In short, the Nokota ECD is one of Applied Materials’ primary high-volume production platforms for 300mm wafer-level packaging electroplating.
