What are the Main Materials of Etch Rings?

2026-05-19

In semiconductor manufacturing, etch rings (more commonly referred to as focus rings or edge rings) are consumable components that surround the silicon wafer inside a plasma etching chamber. Their primary job is to physically protect the electrostatic chuck (ESC) and electrically shape the plasma sheath to ensure uniform etching right up to the very edge of the wafer.   Because they are directly exposed to aggressive, high-energy plasma, they must be made of high-purity materials that resist chemical corrosion and physical sputtering. The most common materials used include:   1. High-Purity Quartz (SiO₂) Historically the most common material, ultra-high-purity quartz (99.99%+ silica) is widely used in fabs due to its clean properties and cost-effectiveness. Best Used For: Silicon etching and applications where minimizing trace metal contamination is critical.  Pros: Extremely pure, low thermal expansion, and lower upfront material cost.   Cons: Erodes relatively quickly when exposed to aggressive fluorine-based plasmas (CF₄, SF₆, NF₃). As it wears down, the altered ring geometry causes "edge drift," forcing frequent tool shutdowns for replacements.   2. Silicon Carbide (SiC) Silicon Carbide—specifically manufactured via Chemical Vapor Deposition (CVD SiC) or high-grade sintering—has rapidly become the mainstream choice for advanced, high-power nodes. Best Used For: High-aspect-ratio (HAR) etching, such as 3D NAND staircase etching and FinFET/GAA fabrication.   Pros: Exceptional hardness and wear resistance. It erodes orders of magnitude slower than quartz in fluorine and chlorine plasmas, significantly extending its lifetime and lowering the tool's Total Cost of Ownership (TCO). It also boasts high thermal conductivity, keeping wafer edge temperatures stable.   Cons: High initial manufacturing and material costs (often 3x to 5x the price of quartz).   3. Single-Crystal (Monocrystalline) or Polycrystalline Silicon (Si) Using high-purity silicon ensures that the focus ring behaves exactly like an extension of the wafer itself. Best Used For: Oxide (SiO₂) etching processes. Pros: Since the ring matches the chemical composition of a standard wafer, any minor material sputtered or etched off the ring introduces absolutely zero foreign elemental contamination into the chamber. Cons: Like quartz, it behaves as a consumable that degrades over time under specific chemistries, requiring routine scheduled replacements. 4. Advanced Ceramics & Coatings For niche or highly corrosive environments, specialized ceramics are deployed:Alumina (AI₂O₃): Provides high mechanical strength and good dielectric performance, though it can shed particles if severely bombarded.Yttrium Oxide (Y₂O₃ / Yttria): Often used as a highly plasma-resistant coating over ceramic or metal ring bases to combat aggressive halogen plasmas.Silicon Nitride (Si₃N₄): Chosen for specific thermal shock resistance and mechanical stiffness requirements.

As foundries in the United States, South Korea, and Japan push the boundaries of nano-scale physics, the role of the photomask substrate has become more critical than ever. Specifically, the 6.6-inch Synthetic Quartz Photomask has emerged as the cornerstone for high-precision lithography. 1. The Foundation of Nano-Scale Accuracy Why is this specific substrate gaining such traction among Tier-1 manufacturers and specialized research labs alike? The answer lies in the intrinsic properties of synthetic quartz—a material engineered to withstand the extreme demands of Deep UV (DUV) light sources while maintaining near-perfect structural integrity. Ultra-Low Thermal Expansion: During high-volume production with intense exposure cycles, even microscopic thermal fluctuations can cause pattern shifts. Synthetic quartz ensures absolute stability in pattern overlay accuracy, preventing costly wafer defects. Superior Optical Clarity: Optimized for i-line, KrF, and ArF lithography, our substrates offer Deep UV (DUV) transmission rates typically exceeding 99%, ensuring crisp and accurate pattern transfer without stray light interference. Zero-Defect Quality: High-purity synthetic silica minimizes internal inclusions and bubbles, which is paramount for maximizing wafer yields in advanced nodes. 2. Strategic Regional Insights: Meeting Global Demand North America: Driving AI and Automotive Chip Resurgence In North America, with the resurgence of domestic manufacturing, there is a surging demand for substrates capable of withstanding long exposure cycles. Our 6.6-inch quartz plates provide the extreme durability required for the production of AI accelerators and high-performance power semiconductors. Asia-Pacific (Japan, Korea, SE Asia): The Hub of Mass Production As world leaders in memory and advanced logic chips, clients in Japan and South Korea demand uncompromising flatness (TIR). Our products strictly adhere to SEMI standards, ensuring seamless integration with mainstream scanners. Meanwhile, we support the transition of Southeast Asian facilities (e.g., Vietnam, Malaysia) from back-end assembly to front-end manufacturing. Australia: Leading in Photonics and Quantum Research In the specialized sectors of quantum computing and specialized sensors, the high transmission of synthetic quartz is key to achieving precise experimental data. 3. Core Technical Specifications Conclusion: Empowering Next-Gen Lithography with High-Purity Optical Solutions As the semiconductor industry pushes toward smaller nodes, the margin for error has virtually disappeared. A photomask is only as reliable as the substrate it is built upon. For manufacturers in high-tech hubs from Silicon Valley to Seoul and Tokyo, our 6.6-inch substrates are the preferred choice for balancing durability with extreme optical clarity.

Lastest company news about BYD Stop Importing Cars into Indonesia - by Calvin WEE from LinkedIn
BYD Stop Importing Cars into Indonesia - by Calvin WEE from LinkedIn

2026-04-15

They stopped importing because their $670 million factory in West Java is coming online. 150,000 units a year, 18,000 jobs, full local production. BYD  is relocating an entire manufacturing ecosystem into ASEAN — factory, supply chain, R&D centre, training facilities.  Indonesia isn't a sales market for them. It's a production base. And this is the part that matters for Singapore: When a Chinese manufacturer builds a 150,000-unit factory in Indonesia, they don't just bring the assembly line. They create an industrial gravitational pull that reshapes how capital, talent, and technology flow through the region. Singapore is not part of that gravitational pull. We don't make things. We finance them, advise on them, and trade them. That's fine — as long as we understand the ecosystems we're financing. But here's the question I keep asking in client meetings and getting no answer to: if you're managing a portfolio with ASEAN exposure, can you explain BYD's Indonesia strategy? Do you understand why they chose Karawang, and what that signals about Indonesia's industrial policy? If not, you're advising on a region you don't fully understand. And your clients will eventually notice. China's ASEAN manufacturing strategy is the single most important structural shift in regional capital flows this decade.  Singapore professionals, especially those in wealth management and advisory, need to understand it at a level deeper than "China is investing in Southeast Asia." The specifics matter. The factory locations matter. The supply chain architecture matters. The regulatory incentives matter.  And right now, not enough people in Singapore's financial sector is paying attention to any of it.

WHAT CUSTOMERS SAYS
Mr. PARK Sang Jun
This is Sang Jun from South Korea. We are sourcing agency for semiconductor parts of quartz, ceramic and silicon. We started the cooperation with Nantong Jingcai Precision since 2024. Their products are of good quality and excellent lead time. We'll keep cooperating for longer time!
Ms. Johanna Krüger
Hi I am Procurement Manager of an RTP equipment manufacturer of Germany. Nantong Jingcai Precision Co., Ltd. is one of our strategic suppliers for key quartz part of the reaction chamber. To be frank, our quartz parts are not easy to be fabricated, but NTJC did great jobs by sending us FA samples with excellent ETD.
Mr. Kenneth James
Hello, my company is engaged in supplying consumable parts to the US fab customers, such as Intel, GF, TSMC and etc. I sent them the part drawings for AMAT and LAM etchers. They quoted me good price and short lead time. So far, I've received more than 10 shipments by air, and I think I'll buy more from them in 2026~
