Diamfab product offering
Product offeringCore offering
Diamfab manufactures synthetic diamond semiconductor wafers (DF-SBD Schottky diode wafers and DF-FET field-effect transistor wafers) using MPCVD growth and proprietary in-situ boron and nitrogen doping. The products are epitaxial diamond layers engineered for high-power, high-temperature, high-voltage, radiation-hardened electronics, as well as quantum applications leveraging NV centers in diamond.
Product overview
DIAMFAB offers a portfolio of synthetic diamond semiconductor products for high-power and extreme-condition electronics, as well as quantum applications. The core product line includes DF-SBD (Diamond Film – Schottky Barrier Diode) wafers for diode fabrication and DF-FET (Diamond Film – Field-Effect Transistor) wafers for transistor manufacturing, both utilizing proprietary MPCVD-grown epitaxial diamond with controlled doping (boron and nitrogen). These are complemented by custom-made products for specialized applications. All products are designed for cleanroom processing and target markets including power electronics, electric mobility, aerospace, nuclear, and quantum computing.

Diamfab competitors and assessment
Company assessmentDirect peers
- AKHAN Semiconductor: US-based developer of diamond semiconductor technology for electronics and optics. Competes head-to-head with DIAMFAB in synthetic diamond wafer and device manufacturing, targeting similar high-power and extreme-condition electronics markets.
- Element Six: De Beers Group subsidiary and the world's leading producer of synthetic industrial diamond, including electronic-grade diamond for quantum and power applications. Most directly comparable peer to DIAMFAB in CVD-grown diamond materials for semiconductors.
- IQE: Global leader in compound semiconductor epitaxial wafer services (MOCVD/MBE) for GaAs, InP, GaN, and SiC. Highly comparable to DIAMFAB's epitaxy service business model delivering doped epi layers to device manufacturers.
Broad incumbents
- Coherent (formerly II-VI): Large compound semiconductor materials company producing SiC substrates and GaAs/InP wafers. Comparable as a wide-bandgap substrate supplier scaling toward power electronics applications that DIAMFAB also targets with diamond.
- Infineon Technologies: Global power semiconductor leader with growing SiC and GaN portfolios. Comparable end-customer-facing competitor in EV and industrial power electronics where DIAMFAB's diamond wafers would ultimately feed.
- Soitec: Global leader in engineered semiconductor substrates (FD-SOI, RF-SOI, Power-SOI, SiC, GaN). Strategic partner and investor-aligned to DIAMFAB but competes in the engineered-substrate category DIAMFAB targets with diamond epi wafers.
- Wolfspeed: Leading pure-play SiC substrate and power device manufacturer. Competes with DIAMFAB in the wide-bandgap power electronics space targeting EV, industrial, and renewable applications where DIAMFAB positions diamond as the next-generation alternative.
- Resonac (Showa Denko): Japanese materials company producing SiC epitaxial wafers and a range of electronic-grade materials. Competes in the wide-bandgap power electronics supply chain that DIAMFAB aims to enter with diamond epi wafers.
- STMicroelectronics: Major European semiconductor IDM with leading SiC and GaN power electronics franchises. Strategic partner of DIAMFAB for nuclear battery development but a key competitor in wide-bandgap power devices where diamond aims to compete long-term.
Regional players
- II-VI / SICC: Chinese SiC substrate supplier scaling capacity for power electronics. Indirect peer reflecting the broader wide-bandgap substrate competitive landscape DIAMFAB must navigate to reach power-converter OEMs globally.
