5 reasons why Electroforming is the best choice for semiconductor testing solutions

As integrated circuits (ICs) become increasingly complex and wafer designs become more intricate, the tools and components used in wafer testing face more and more challenging demands for accuracy, durability, and reliability. Electroforming has emerged as the preferred solution for producing intricate, high-precision components essential for semiconductor wafer testing. This blog reviews 5 reasons why Electroforming stands out among the manufacturing technologies.

1. umparalelled highprecision down to 1 micron

Electroforming is an advanced Additive Manufacturing process that "grows" high-precision metal parts atom by atom. With precision down to 1 micron, this extremely accurate manufacturing technique enables the production of metal components with complex designs and unmatched accuracy. As the industry leader, Veco is the first in the industry to apply the cutting-edge Laser Direct Imaging (LDI) technology in the Electroforming process for the production of high-precision metal parts. With the industry-leading Advanced Lithographic Electroforming technology, high quality, extreme accuracy, and fast turnaround can be achieved without additional tooling costs, making it particularly suitable for semiconductor testing solutions.

2. scalability and repeatability from prototype to production

Electroforming excels in both scalability and repeatability, allowing manufacturers to transition seamlessly and smoothly from prototyping to full-scale production. Unlike many traditional manufacturing methods that require additional tooling or process adjustments for increased volumes, Electroforming applies the same processes from prototype to mass production, guaranteeing uniformity across every piece. Besides, lead times are short for both prototyping and production with Electroforming, giving companies the agility to rapidly iterate and respond to evolving test requirements. This is particularly valuable in the semiconductor industry, where frequent design changes and fast innovation cycles demand solutions that can quickly adapt while maintaining the highest standards of precision and quality.

3. advanced materials for superior performance: HR Nickel and more

As the world-leading specialist in Electroforming, Veco has developed unique Electroforming materials that revolutionize semiconductor testing capabilities. Heat Resistant (HR) nickel, for example, is specifically engineered to withstand the thermal stresses common in rigorous semiconductor testing environments. It provides exceptional heat resistance and conductivity, enabling components to undergo extensive testing without material degradation. In practical applications, HR nickel components can perform several million test cycles before showing signs of wear, representing up to three times the durability of conventional materials. This enhanced longevity significantly reduces failure rates and makes testing processes faster, more reliable, and more cost-effective without compromising quality standards. Veco is also conducting further research into HR+ nickel that promises even greater heat resistance capabilities, pushing the boundaries of what's possible in high-temperature testing environments.

4. co-development with the experimental approach

Successful implementations of Electroforming technology in developing and producing semiconductor testing solutions often involve close partnerships. At Veco, these collaborative relationships go beyond traditional supplier-customer arrangements, involving application engineering resources, co-development projects, and customized solutions. Veco's expertise in Electroforming technology and collaborative co-development approach (learn more about co-development with Veco) make us the partner of industry leaders, empowering next-gen industry innovation. Our application engineering and R&D teams work closely with customers to create products, combining our knowledge and experience to design, prototype, and scale up to industrial production. Our co-development approach has proven particularly valuable for pushing technological boundaries, such as driving component sizes into the miniaturized range and developing new materials with enhanced performance characteristics.

5. process control and manufacturing excellence

Achieving the precision required for semiconductor testing applications demands rigorous process control throughout the Electroforming process. The lithographic process, combined with Electroforming, enables near-perfect process control and high repeatability in component production. Even the most delicate or intricate parts can be produced with outstanding repeatability and defect-free quality, a necessity for semiconductor testing where reliability and accuracy are paramount. In addition to its precision and process control, Electroforming technology enables the creation of complex features and 3D structures through multi-layer deposition (learn more about "3D Electroforming"). With the additive process, additional layers can be "grown" in specific directions, resulting in complex 3D or 2.5D geometries. This capacity creates new opportunities for delicate product design and is especially useful for complicated semiconductor applications where multiple materials are combined in use, making sure the best material functions in the perfect location.
