Electronic Grade Diamond Purity Specifications by ViQium

Understanding Electronic Grade Diamond Purity Requirements

For semiconductor manufacturers, optical engineers, and quantum device developers, the term “electronic grade diamond” typically points to a material defined by exceptionally tight control over lattice impurities rather than a single universal metric. Within this context, ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, has built its High Purity Diamond product line around the specific purity parameters that directly govern electronic and optical performance: nitrogen content, boron content, and carbon-12 enrichment.

Core Purity Specifications of ViQium’s High Purity Diamond

ViQium’s High Purity Diamond is engineered with the following documented parameters:

• Nitrogen content: below 5 ppb
• Boron content: below 1 ppb
• Carbon-12 enrichment: 98.9%

These three parameters are the foundation of what makes a diamond suitable for demanding electronic and photonic applications. Low nitrogen and boron concentrations reduce unwanted lattice defects and charge carriers that can interfere with signal clarity, while high carbon-12 enrichment minimizes isotopic disorder within the crystal lattice. According to ViQium’s product documentation, this High Purity Diamond material is “widely used in semiconductors and electronics, optical windows, and both single and shallow NV-center fabrication.”

Available Product Configurations

ViQium offers its High Purity Diamond in multiple crystal orientations and dimensions to accommodate different downstream fabrication needs. 

Beyond these standard configurations, ViQium provides product customization along with factory calibration and characterization data, allowing customers to verify material properties before integrating the diamond into their own processes.

Why Purity Control Matters for Electronic and Sensing Applications

ViQium’s strategic positioning centers on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials. The company’s founding team draws on more than eight years of dedicated research in advanced quantum materials, including NV center quantum diamonds, with expertise spanning material synthesis, defect engineering, and device integration. This background directly informs how the High Purity Diamond line is produced: ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing, which supports precise control over impurity levels during fabrication.

This level of control is particularly relevant because high purity diamond substrates serve as the starting material for further processing into single NV diamond and shallow NV diamond products. As noted in ViQium’s technical materials, the same high-purity substrates that support semiconductor and optical window applications also form the basis for single and shallow NV-center fabrication, connecting electronic-grade purity requirements directly to the company’s broader quantum diamond material portfolio.

Manufacturing Capabilities Supporting Consistent Quality

ViQium has established a comprehensive technology platform for fabricating NV centers in diamond through both high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) methods. This platform supports controllable fabrication of quantum diamond materials, and the company’s broader product portfolio spans bulk, micro-scale, and nano-scale quantum diamond materials. For customers focused specifically on high purity diamond for electronic applications, this manufacturing infrastructure translates into consistent material quality and traceable production records.

ViQium implements batch-level control and traceability management throughout the entire process of diamond material production and delivery, which helps ensure performance stability and consistency across different material batches. This is a meaningful consideration for electronics and semiconductor customers, who often require repeatable material characteristics across production runs.

Delivery and Technical Support

Standard products from ViQium can be delivered within 28 days, while conventional customized products can be delivered within 45 days. This timeline applies across ViQium’s quantum materials series, including the High Purity Diamond line, giving customers a defined expectation for procurement planning.

ViQium’s service framework covers the entire process from requirement alignment, solution design, and sample validation through to delivery implementation and application support. For customers without prior experience specifying diamond materials for electronic or optical applications, ViQium provides tailored technical guidance covering material characteristics, operating procedures, and key experimental considerations, supporting effective material utilization and reliable reproducibility.

Addressing Common Customer Challenges

Many first-time buyers face difficulty establishing clear reference standards when selecting diamond materials, particularly in determining the optimal crystal orientation for specific applications. ViQium addresses this by categorizing products based on application requirements and offering professional online consultation, reducing the need to purchase multiple samples for comparison purposes.

Additionally, ViQium combines flexible small-batch customization with in-house fabrication capabilities, allowing key parameters such as crystal orientation, sample dimensions, and microstructure processing to be tailored to specific project requirements. This flexibility extends to the High Purity Diamond line, where customers can request configurations beyond the standard catalog codes.

Target Applications and Customer Base

ViQium’s High Purity Diamond materials are positioned to serve research institutes and universities pursuing fundamental physics validation, as well as advanced industrial inspection and precision manufacturing companies working in semiconductor inspection and related fields. These customer segments typically prioritize technical performance, product pricing, delivery timelines, and ongoing technical support—areas that ViQium addresses through its documented specification transparency and customization options.

Summary

For organizations searching specifically for thermal conductivity figures in electronic grade diamond, it is worth noting that ViQium’s published specifications for its High Purity Diamond line center on nitrogen content, boron content, and carbon-12 enrichment rather than thermal conductivity values. These purity metrics remain central to determining suitability for semiconductor, electronics, and optical window applications, and they form the material foundation from which ViQium’s single and shallow NV-center diamond products are subsequently fabricated. Customers evaluating electronic grade diamond options can request factory calibration and characterization data directly from ViQium to confirm whether specific batches meet their application requirements.
