“Do you have any in stock? I want to buy directly.”
This is the question our sales team at Rich Special Materials Ltd. hears most often. Many customers, when they first approach us, instinctively assume that sputtering targets—like ordinary industrial supplies—come with ready-made specifications and inventory, orderable by simply quoting a model number.
But our answer is almost always: “It needs to be customized according to your requirements.”
Why? Does that mean we’re too small to keep stock? — Quite the opposite. The reality that sputtering targets are ”not off-the-shelf, but made-to-order” is dictated by technical fundamentals, not a choice made by any single manufacturer, but the ground rule of the entire industry.
Customer Equipment Comes in “A Thousand Faces” — No Unified Sizes
Sputtering targets are critical consumables installed in customers’ coating equipment. The challenge is that different manufacturers, different generations of production lines, and different machine models all demand entirely different shapes and sizes for targets.
Planar targets, rotary targets, custom-shaped targets — each has its own exclusive specifications. A target designed for Customer A’s chamber likely won’t even fit into Customer B’s equipment, and even if it does, the sputtering performance would be completely off.
That’s exactly why Beijing Rui Chi’s product specifications are often listed as “machined or custom-made per drawing.” It’s not that we don’t want to offer standard products — it’s that target dimensions are inherently non-standard.
Customer Applications Vary Endlessly — No Universal Compositions
Beyond dimensions, the composition of a target also has no “standard answer.”
Take alloy targets as an example: for semiconductor chips, purity must reach above 99.995%; for decorative coatings, purity requirements are less extreme; for aerospace high-temperature components, oxidation-resistant and corrosion-resistant high-entropy alloys are needed; for smart devices, specific electrical or optical properties are required.
The composition is determined by the customer’s end product and process requirements, not pre-set by the manufacturer. Rich Special Materials Ltd. 20+ years of accumulated experience lies precisely in our ability to flexibly adjust composition, purity, and microstructure according to customer needs, rather than offering a one-size-fits-all standard product.
No “Universal Formula” for Manufacturing Processes
Even when customers provide composition requirements and dimensional drawings, transforming different metals with varying melting points and distinct characteristics into a high-quality, homogeneous target is itself a monumental technical challenge.
Some materials are best processed by vacuum melting; others, due to significant melting-point differences or special compositions, must go through the powder metallurgy route. The same alloy formulation may correspond to completely different process parameters, equipment settings, and quality standards.
Beijing Rui Chi is equipped with both vacuum melting and powder metallurgy capabilities precisely to choose the optimal process route based on material properties. This ”one-to-one” manufacturing model means every batch is custom-tailored — mass stockpiling is simply not feasible.
Long Customer Qualification Cycles Make “Off-the-Shelf” Impractical
Even if we pre-produced “standard” targets, would customers dare to use them directly?
For high-end applications like semiconductor chips and advanced optical coatings, the qualification process is extremely rigorous — technical review, sample testing, pilot runs, stability validation, and mass production — the entire cycle often takes years.
Once a target passes a customer’s process qualification, a long-term, stable partnership is formed, and the customer will not easily switch suppliers. This means that each qualified target is essentially ”deeply bonded” with a specific customer — producing “stock” in advance is neither necessary nor realistic.
We Hope You Understand:
It’s not that we don’t keep stock — it’s that every single target deserves to be custom-tailored for your unique process.
If you have any custom target needs — whether small-batch R&D or industrial-scale production — please reach out to Rich Special Materials Ltd. Let customization become your competitive advantage.
