Precision Crystal Wafer
Manufacturing
Jingxin is a lithium niobate and lithium tantalate wafer manufacturer growing LiNbO3 and LiTaO3 single crystals in-house using the Czochralski method, and processing quartz wafers from qualified sourced material. Every wafer is processed through slicing, lapping and CMP polishing, cleaned, inspected and cleanroom-packaged at our own facility in Zhuji, Zhejiang — SAW-grade and optical-grade wafers, 3" to 8" in diameter, with quality and lead time under our direct control.
Lithium Niobate, Lithium Tantalate & Quartz Wafers
In-house grown, processed and inspected. We supply lithium niobate wafers, lithium tantalate wafers and quartz wafers — including black lithium niobate and MgO-doped lithium niobate variants — from 3" to 8" in diameter, plus contract wafer processing services.
LiNbO3 (Lithium Niobate) Wafers
SAW-grade and optical-grade LiNbO3 wafers, 3" to 8" in diameter, with X/Z/Y and rotated-Y cut orientations (Y41°, Y64°, Y128°). Used in SAW filters, RF front-end modules and electro-optic modulators.
LiTaO3 (Lithium Tantalate) Wafers
SAW-grade and optical-grade lithium tantalate wafers, 3" to 6" in diameter, with higher electromechanical coupling than LiNbO3. Cut orientations include X112°, Y28°, Y36°, Y42° and YZ — the substrate of choice for high-end SAW filters.
Quartz Wafers
Synthetic α-quartz wafers, 3" to 6" in diameter, in AT, BT, CT, DT, GT, SC and IT cut orientations — extremely low temperature coefficient and high Q value for frequency control and timing devices.
Custom Wafer Processing Services
Contract slicing, lapping, CMP polishing, cleaning and inspection for LiNbO3, LiTaO3, quartz and other piezoelectric or optical crystal materials, up to 8" in diameter — your material or ours.

Our Zhuji, Zhejiang facility runs the full wafer manufacturing process in-house — crystal growth, orientation, slicing, chamfering, lapping, CMP polishing, cleaning and full-spec inspection — for LiNbO3, LiTaO3 and quartz wafers, 3" to 8" in diameter. We also offer contract wafer processing services for customer-supplied crystal materials.
LiNbO3 and LiTaO3 crystals are grown in-house using the Czochralski method; quartz material is sourced and verified before entering the same line. Each is then oriented and sliced into standard-diameter ingots before moving through chamfering, lapping and CMP (chemical mechanical polishing) — the stages that bring wafer flatness and surface cleanliness up to SAW-grade or optical-grade specification. Cleaning removes particles and residue from processing, after which every wafer is individually inspected on TROPEL and Candela CS20 metrology equipment for thickness, warp and surface particle counts. Wafers that pass inspection are graded and packaged in a cleanroom to prevent contamination or damage in transit.

Where Our Materials Are Used
From RF front-end filters in telecom base stations to electro-optic modulators in optical communication systems, from infrared sensors to precision timing circuits, Jingxin's lithium niobate, lithium tantalate and quartz wafers are specified into the core material list of several high-precision electronic systems. Each application places different demands on material grade and cut orientation — these are the four categories where our wafers are used most.
SAW Filters & RF Front-End
SAW (surface acoustic wave) filters depend on piezoelectric material with high electromechanical coupling and precise, stable cut orientation. Our SAW-grade LiNbO3 and LiTaO3 wafers are supplied to base station RF front-end and mobile handset filter manufacturers where filtering performance is critical.

Optical Comm & Photonics
Electro-optic modulators require material with high optical homogeneity and low absorption. Our optical-grade lithium niobate wafers are tested to tight optical specifications and also support LNOI (lithium niobate on insulator) thin-film processing for high-speed photonic devices.

Pyroelectric Sensors
Lithium tantalate's strong pyroelectric effect makes it the core sensing material for infrared detectors. Our LiTaO3 wafers are supplied for flame detection, gas analysis and PIR motion-sensing applications.

Frequency Control
Quartz crystal's low temperature coefficient and high Q value have long made it the standard material for oscillators and resonators. We supply quartz wafers in AT, BT, SC and other cut orientations for timing circuit designs with varying frequency-stability requirements.

For most customers evaluating a new supplier, the real risk isn't the first sample — it's whether that sample can be repeated at volume. Jingxin has kept full in-house production as a non-negotiable from day one: every step from crystal growth to cleanroom-packaged wafers happens inside our own facility in Zhuji, Zhejiang, so quality, timing and technical support stay under one roof instead of being split across subcontractors.
Full In-House Production
Crystal growth, slicing, lapping, CMP polishing, cleaning and inspection all run on the same production line, not outsourced piecemeal across vendors. Every step from ingot to finished wafer stays under our direct control — no delays or spec mismatches caused by coordinating multiple external processors.
Direct Production Contact
Quotes and lead times come straight from the engineers running the line, not a layer of sales intermediaries. For custom cut orientations, non-standard thickness or rush orders that need a technical judgment call, you get an accurate, actionable answer the first time, not a delayed relay through account management.
Broad Material & Grade Coverage
LiNbO3, LiTaO3 and quartz, across SAW-grade, optical-grade, black lithium niobate and MgO-doped variants, in diameters from 3" to 8". Whether your project needs a single material or a mix of substrates, you can source it from one supplier and simplify your supply chain instead of qualifying multiple vendors.
Certified Quality System
Our facility is ISO 9001 and ISO 14001 certified, with a documented, auditable process from raw material to finished wafer. Every batch is individually inspected on TROPEL and Candela metrology equipment for thickness, warp and surface particle counts, with traceable inspection data on request.
Have a wafer spec in mind?
Whether you need standard-spec wafers or a custom cut orientation, thickness or surface finish, send us your material, grade, diameter and thickness — our production engineers will get back with a quote, lead time and any technical recommendations within 1-2 business days.
