The target quality is rather significant for the coating process, and targets’ features are affected by a variety of parameters like purity, density, porosity, grain sizes, shapes, etc. The better the target quality is, the better performance we have, and the firmer the coating layers are. Here we will discuss the details of how these characteristics of sputtering targets influence coating quality in this article.

Purity is one of the key factors affecting coating quality because impurities would cause lots of problems for the sputtering process.
Generally, there are mainly 3 kinds of impure content in the coating-making process– impurities in solids, oxygen, and water vapor. If these materials enter the vacuum chamber, they could not adhere to the surface of the substrate. Consequently, several coatings would not be firmer enough as expected, and they would even peel off. Therefore, effective measures should be taken to acquire high-purity targets.
Let’s further explain the danger of impure content with the specific case of the copper target. A small amount of sulfur is usually introduced to obtain suitable grain sizes for the target. However, if the sulfur content exceeds 18 ppm, micro-cracks can appear in the target, and discharge comes. Impurities could lead to cracks and discharges for Si-Al targets as well. Therefore, we’d better use high-quality targets with purity as high as possible.

Target density is another crucial factor affecting coating quality.
The density of target pieces not only has a great influence on their performance in the sputtering process but also determines the electrical and optical features of films. Additionally, high-density targets are needed to withstand the high temperature and pressure in the chamber. Actually, the casting target’s relative density should be over 98%, and the powder metallurgy target is supposed to exceed 97%. The relative density should be more than 90% generally.
Porosity also matters, and it is closely related to target density.
Low-density target materials usually have a loose and porous structure, which introduces high oxygen content and other impurities. Hence, the whole coating-making process is contaminated. Cracks and discharge situations happen consequently. Materials might be burnt out sometimes. Therefore, high-density target materials should be employed to prevent these problems.
There are many more elements influencing the coating preparation.

Experience is the foundation of reliability. A manufacturer with years of expertise in sputtering target production understands the nuances of materials and processes, ensuring consistent results. Look for a supplier with a strong track record in your industry—whether semiconductors, solar energy, or optics—as they’re better equipped to offer tailored solutions. For example, a semiconductor-focused manufacturer will know the specific requirements for indium tin oxide (ITO) targets, while an optics supplier excels in high-purity hafnium. Additionally, manufacturers with advanced design capabilities can optimize target shapes to maximize material use and performance.
Quality determines the success of your thin films. High-purity targets (e.g., 99.99% or 99.999%) minimize defects, while high-density and uniform grain structures enhance deposition efficiency. Choose a manufacturer with ISO certification to guarantee robust quality management. Ask about their testing methods, such as X-ray analysis or glow discharge mass spectrometry (GDMS), to verify material purity. A reliable supplier will provide detailed specifications and ensure targets meet your equipment’s needs, whether planar or rotary.
Flexibility is key to meeting unique project demands. A strong manufacturer offers a wide range of materials—metals, alloys, ceramics—and target types to suit various applications. They should also provide customization options, tailoring dimensions, compositions, or backing plates to your deposition system. This is especially critical for industries like solar energy, where specific conductive materials are required, or automotive, where large-area targets are common. Confirm their ability to deliver accessories that improve deposition efficiency.
Value matters more than the lowest price. While competitive pricing is important, focus on long-term cost savings through quality and efficiency. Some manufacturers offer value-added services like spent target recycling or flexible payment terms, which can significantly reduce expenses, particularly for precious metals. Environmentally conscious suppliers may also recycle materials, aligning with sustainability goals and cutting waste. Request transparent pricing and evaluate the overall return on investment.
Timely delivery keeps your projects on schedule. A dependable manufacturer has a proven record of fulfilling orders accurately and on time, even for large or urgent requests. They should maintain sufficient inventory and have robust supply chain management to avoid disruptions from raw material shortages. This is especially critical in volatile markets, where delays can derail production. Ask about their logistics processes and contingency plans to ensure reliability.
Strong communication builds trust. A manufacturer that responds quickly and clearly during initial inquiries is likely to provide ongoing support. Look for suppliers offering technical consultation to help select the right targets and troubleshoot issues. Easy ordering processes and accessible documentation are also signs of a customer-focused partner. Test their responsiveness early to gauge their commitment to your success.
Precious metal targets, such as gold, silver, or platinum, demand extra scrutiny due to their high cost and specialized requirements. Partner with a manufacturer experienced in precious metals to manage costs and ensure quality. They should excel in refining and processing these materials, handling price volatility, and meeting stringent purity standards. Optimized target designs can reduce material waste, lowering expenses during market fluctuations. Additionally, look for recycling programs that recover valuable materials from spent targets—sometimes up to 50% of a gold target—offsetting future costs. Flexible payment terms or inventory management can further ease financial pressures. For industries like aerospace or glass manufacturing, ensure the supplier is familiar with relevant certification processes to meet regulatory demands to ensure compliance.
To choose the right partner, follow these streamlined steps:
Test with Samples: Request trial targets to evaluate purity, density, and compatibility with your system. This minimizes risks before large orders.
Review Feedback: Ask for case studies or client references to confirm the manufacturer’s reliability and expertise in your industry.
