Meeting the Demand for High Purity Electronic Grade Diamond

Diamond materials used in semiconductors, electronics, and advanced quantum applications require an exceptionally clean crystal lattice, precise dimensional control, and consistent batch-to-batch performance. ViQium Technologies Co., Ltd., a Shanghai-based company focused on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials, addresses this need through its High Purity Diamond product line. Built on a complete in-house production process covering diamond crystal growth, ion irradiation, and high-temperature annealing, ViQium provides materials suited for semiconductor inspection, optical windows, and both single and shallow NV-center fabrication.

Inside ViQium’s High Purity Diamond Product Line

The High Purity Diamond product is defined by strict material-grade specifications: nitrogen content below 5 ppb, boron content below 1 ppb, and carbon-12 enrichment of 98.9%. These parameters position the material for use in semiconductors and electronics, optical windows, and as a substrate for subsequent single and shallow NV-center fabrication.

The product is offered under multiple codes reflecting different crystal orientations and dimensions, including HPD100F12 (<100>, 220.5 mm), HPD100F13 (<100>, 330.5 mm), and HPD111F12 (<111>, 220.5 mm and 330.5 mm). This range allows researchers and industrial buyers to select an orientation and size that aligns with their specific fabrication or characterization requirements rather than being restricted to a single fixed configuration.

Customization Capabilities for Large-Size, High Purity Requirements

For customers requiring custom large size, high purity electronic grade diamond, ViQium’s stated customer service for this product line includes product customization along with factory calibration and characterization data. This is consistent with ViQium’s broader customization platform, which supports flexible orders starting from a single piece and covers diverse specifications and crystal orientations, including (111)-oriented materials.

According to ViQium’s disclosed delivery framework, standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days. This timeline structure gives customers a clear expectation when planning experiments or production schedules that depend on receiving diamond materials with specific dimensions or purity characteristics.

End-to-End Technical Support and Quality Assurance

Beyond the material itself, ViQium has established an integrated service chain covering diamond growth, NV center creation, characterization, and ODMR system integration. For customers working with high purity diamond substrates intended for later NV-center fabrication, this means technical support does not stop at material delivery. Based on customer requirements, ViQium provides customized material selection, testing solutions, competitive benchmarking, and experimental optimization recommendations, along with long-term technical support throughout the R&D process.

Quality control is addressed through batch-level control and traceability management applied throughout the entire production and delivery process, aimed at ensuring performance stability and consistency across different material batches. For technical information and project data generated during customer applications, ViQium applies internal access control and information segregation mechanisms to protect the security and independence of technical and application-related data. Customers also receive technical training covering material characteristics, operating procedures, and key experimental considerations, supported by a collaborative mechanism between sales and R&D teams that enables direct technical response and remote collaboration for urgent issues.

Addressing Common Customer Challenges

ViQium’s published case material identifies a recurring industry challenge: "Limited Access to Small-Batch Customization and High-Performance NV Diamond Materials." As described in ViQium’s own case documentation, leading international suppliers typically do not support small-volume customized orders, and even suppliers offering small-batch production often show gaps in key material parameters such as concentration, uniformity, and coherence time.

ViQium’s stated solution combines flexible small-batch customization with advanced in-house fabrication capabilities. Key parameters — including crystal orientation, NV concentration, sample dimensions, and microstructure processing — can be tailored to specific requirements. The company states that its high-density NV diamond materials deliver performance comparable to high-end products, paired with more competitive pricing and shorter delivery cycles for customized orders. While this specific case reference centers on NV diamond materials, the same in-house fabrication infrastructure — spanning diamond crystal growth, ion irradiation, and annealing — underpins the High Purity Diamond line as well.

Target Applications Across Research and Industry

ViQium describes its NV center quantum diamond technology, including related high purity diamond materials, as primarily serving quantum precision measurement and advanced sensing, with applications spanning fundamental scientific research, industrial precision inspection, and extreme-environment detection. Specific application areas named in ViQium’s materials include semiconductor inspection, power metrology, geological exploration, and aerospace & defense.

For research institutes and universities, ViQium notes that the core demand is obtaining high-quality, reproducible quantum materials and accessible experimental platforms to support fundamental physics validation. These customers typically prioritize technical performance, product pricing, delivery timelines, and technical support, and often face challenges related to unstable experimental results and insufficient reproducibility.

For advanced industrial inspection and precision manufacturing companies, including those in semiconductor inspection, power measurement, and geological exploration, the stated priority is overcoming performance limitations in precision measurement while gaining system integration, long-term operational reliability, customization capabilities, and scalable supply capacity.

Company Background Supporting Technical Credibility

ViQium’s technical foundation stems from a founding team with academic backgrounds from several leading universities in China and more than eight years of dedicated research in advanced quantum materials, including NV center quantum diamonds and black phosphorus. Through continuous work in material synthesis, defect engineering, and device integration, the company has built differentiated technological capabilities across key stages of quantum material development, combining expertise in quantum physics, materials science, and optical engineering with precision manufacturing experience.

For organizations evaluating custom large size, high purity electronic grade diamond for semiconductor, optical, or NV-center fabrication purposes, ViQium’s combination of documented material specifications (nitrogen below 5 ppb, boron below 1 ppb, carbon-12 enrichment of 98.9%), defined delivery timelines, batch-level traceability, and end-to-end technical support represents a structured, verifiable pathway from material selection to application deployment.
