TFLN Photonic Foundry Services
From Prototyping to Industrial-Scale Wafer Manufacturing
CCRAFT is an independent pure-play thin-film lithium niobate (TFLN) photonic foundry, delivering advanced chip manufacturing services from prototyping to industrial-scale production.
Built on years of intensive R&D and manufacturing know-how, we offer MPW runs, dedicated wafer fabrication, TFLN chiplets and specialized processing services. Our engineers manufacture chips today while we scale toward the world's first dedicated TFLN photonic fab.
Our Solutions
Monolithic TFLN Chips
Fabricated on lithium niobate on insulator (LNOI) substrates using up to 10 main advanced process steps for full photonic integration.

TFLN Chiplets
Chiplets compatible with micro-transfer printing, enabling cost-effective, customizable, and scalable heterogeneous integration.
TFLN-Enhanced Silicon Photonics
TFLN micromachining services to support SiPh fabs and platform developers looking to integrate TFLN into their workflows.
We Offer
Multi-Project Wafer (MPW)
Ideal for: Prototyping, research, early-stage validation
Volume: Shared wafer access
Cost: Entry-level, $/mm²
We offer MPW services based on our standardized TFLN platform and the process design kit (PDK). Customers can access high-performance photonic technology at low cost by sharing wafer area, perfect for proof-of-concept designs or academic projects.

Custom Dedicated Wafer Runs
Ideal for: Pre-production, product integration, process qualification
Volume: Dedicated wafers, minimum order 4 wafers
Cost: Scales per wafer or per chip based on order size
When your design requires more space, flexibility, or tailored process steps, or you deliver to niche markets, we offer dedicated wafer runs on our industrial-grade TFLN platform. Custom runs give you full control over layout, design integration, and fabrication parameters — enabling you to fine-tune your product or system before moving to scale.
This option is also ideal for qualification and validation prior to high-volume production, helping de-risk your transition from prototyping to manufacturing.
High-Volume TFLN Manufacturing
Ideal for: Industrial-scale photonic chip production
Target capacity: 2,000 wafers per month
CCRAFT already manufactures and delivers TFLN chips through MPW and dedicated wafer runs. Building on years of industrial R&D and manufacturing experience, we are establishing a dedicated TFLN fab to scale production to 2,000 wafers per month.
Our industrialization roadmap focuses on reproducible processes, consistent quality and scalable manufacturing, enabling customers to move confidently from prototype to volume production.
Specialty Process Services on TFLN and Related Materials
Ideal for: Platform developers, foundries, and R&D partners
Volume: From 4 wafers and up
Cost: Project-based, depends on process steps and volume
We offer targeted fabrication services for customers needing specific processing steps on TFLN and similar materials. This includes etching, metal deposition, oxide deposition, and periodic poling, tailored primarily for integrated photonic applications.
We support both prototype-level engagements and scalable volume production, acting as a flexible and collaborative partner throughout the development cycle.
