Exawatt’s research includes a comprehensive understanding of SiC crystal growth, epitaxial deposition and front-end device manufacturing processes and cost

Talk to our team

We have developed cost models for all aspects of SiC supply chain, including capital expenditure (capex) and depreciation, energy costs, consumables cost, operating costs, cycle times and equipment productivity and yield.

Our cost models cover the following:

  • SiC crystal growth, wafering and epitaxy – Exawatt has developed detailed cost models and forecasts for SiC crystal growth, wafering cost, and epitaxial growth. This includes competing crystal growth technologies, 200mm wafers and alternative wafering technologies. We use our models to create forecasts for wafer price and later steps in the supply chain.
  • Device fabrication – Exawatt’s device fabrication cost models, including front- and back-end production, are based primarily on extensive conversations with, and on information shared by, multiple industry stakeholders. These models feed into our device and module price forecast, which informs our market forecasts.
  • System integration – Exawatt is developing detailed system-level cost models, from EV converter costs (inverter, on-board charger and charging station) through to battery costs and vehicle integration costs. This enables Exawatt to develop a full system-level cost-benefit analysis for SiC

In 2023, Exawatt was acquired by CRU, a company that provides first-hand knowledge of different commodity markets, including those relevant to power electronics. CRU strengthens our capacity for cost modelling and forecasting.

Steve Lambert, Head of Electrification, McLaren Applied
“If you are interested in how the market for power electronics will grow, particularly in automotive, then I would highly recommend the work done by Exawatt. Exawatt’s market intelligence and forecasting has been invaluable for helping shape our strategy for developing and taking to market McLaren Applied’s class-leading power electronics-based products. The team is knowledgeable, enthusiastic and great to work with.”

Rae Hyndman, Managing Director at Clas-SiC Wafer Fab
“The market reports produced by Exawatt for the ESCAPE project have been invaluable to Clas-SiC Wafer Fab, providing us with up-to-date information on the silicon carbide supply chain, market trends and forecasts. Exawatt is very knowledgeable in the area of power electronics and the team is great to work with.”
