Engineering the Crystal Materials Behind Modern Photonics
Jingxin New Materials (Zhuji) Co., Ltd. is a lithium niobate and lithium tantalate wafer manufacturer specializing in the R&D, production and sales of piezoelectric crystal materials — from LiNbO3 and LiTaO3 wafers to next-generation thin-film substrates — supporting SAW devices, optical communication and RF front-end applications.
Who We Are
Jingxin New Materials production facility — Zhuji, Zhejiang, China
Where It Starts
Raw Crystal Ingot
Jingxin New Materials (Zhuji) Co., Ltd. was founded in 2024 and is based in Zhuji, Zhejiang Province, China. As a lithium niobate and lithium tantalate wafer manufacturer, we specialize in the R&D, production and sales of piezoelectric crystal materials. Since our founding, we've built the business around one core capability: turning raw LiNbO3, LiTaO3 and quartz crystal into precision wafers that meet each customer's exact specification, with an in-house line covering crystal growth, slicing, lapping, CMP polishing, cleaning, inspection and cleanroom packaging. The company has passed evaluation as a Technology-based SME.
Building on our in-house crystal growth and wafer processing capability, Jingxin has achieved mass production of 8-inch large-diameter lithium niobate wafers, solved the mass-production challenges specific to 3–6 inch ultra-thin wafers, and industrialized a blackening process for lithium niobate wafers. These milestones are backed by a process engineering team with two to three decades of hands-on experience in crystal growth and precision wafer fabrication — the foundation that lets us take on non-standard specifications and respond quickly to customer-specific requirements.
For customers in SAW filters, RF front-end modules, optical communication systems and integrated photonics, working with a wafer supplier like Jingxin means not having to coordinate lead times and specifications across multiple vendors, and not having to worry about a sample that can't be repeated at volume. From raw ingot to finished wafer, the entire production line stays under our own roof — quality, lead time and technical support are owned by one team, start to finish.
Jingxin New Materials is committed to becoming a trusted supplier in the piezoelectric and photonic crystal materials industry, with continued investment in advanced processes such as optical-grade lithium niobate crystal growth — delivering more stable, higher-precision material solutions for SAW devices, optical communication, infrared sensing and frequency control applications.

Technology Milestones
Behind every milestone on this timeline is a process engineering team with two to three decades of hands-on experience in crystal growth and precision wafer fabrication. That depth of experience is why we can take on non-standard specifications, troubleshoot process issues quickly, and keep quality consistent as we scale — capabilities that matter more to our partners than production capacity alone.
Developed proprietary wafer restoration technology to address yield loss from micro-cracks and chipped edges during processing, and industrialized a blackening process for lithium niobate wafers to meet customer demand for light-blocking, anti-static wafers.
Solved the industry-wide challenge of warping and edge chipping in 3–6 inch ultra-thin wafers during slicing and polishing, through process parameter optimization and equipment modification — achieving stable volume production at mass-production yield levels.
Completed process validation and production-line integration for 8-inch large-diameter lithium niobate wafers, with flatness and thickness uniformity meeting both SAW-grade and optical-grade standards — expanding our large-diameter wafer supply capability.
Formally launched an optical-grade lithium niobate crystal growth initiative, targeting improved optical homogeneity and absorption coefficient to support higher-spec material requirements for electro-optic modulators and photonic integrated chips.
Based in Zhuji. Built for Global Delivery.
Zhejiang isn’t just where our factory happens to be — from equipment sourcing and skilled technicians to export logistics, the manufacturing cluster around Zhuji is part of what lets us deliver reliably to customers overseas.
Mature Manufacturing Ecosystem
Zhejiang has a deep base of precision equipment suppliers and skilled technicians. From crystal growth furnaces to CMP polishing equipment, parts sourcing and repair support are available locally, so our production line doesn’t face long lead-time waits for components or technical expertise.
Efficient Export Logistics
Our factory sits close to Zhejiang’s major export ports, shortening inland transit times for shipments to customers worldwide, with mature customs clearance and inspection processes that keep the overall logistics cycle tighter.
Direct Line to Engineering
Our sales and technical teams work in the same facility as the production line, not behind layers of subcontractors — questions about custom cut orientations, thickness adjustments or rush scheduling get a real, accurate answer on the spot.
Equipment & Processing
A few snapshots from our cleanroom production line — and it’s only part of the picture. From crystal growth furnaces to CMP polishing equipment, from optical inspection stations to cleanroom packaging, our capability spans all 12 processing steps from crystal growth to final packaging, each with dedicated equipment and standardized procedures. See the full manufacturing process for the complete picture.
Processing Line
CMP Polishing
Chemical mechanical polishing brings wafer surface flatness and roughness up to SAW-grade or optical-grade specification.
Quality Control
Optical Inspection
Interferometry and other optical metrology tools verify wafer flatness and optical quality on every piece, with traceable inspection data.
Handling & Storage
Wafer Cassette Carrier
Cleanroom-dedicated cassettes keep wafers separated to prevent cross-contamination and support batch tracking through the line.
