List the World's Silicon Carbide Wafer Suppliers

As of 2024, the silicon carbide (SiC) wafer market comprises several influential suppliers globally. Key players in this industry include:

  1. Wolfspeed Inc.: A prominent name in the SiC wafer market, known for expanding and extending its 100mm silicon carbide wafersupply agreements with other global semiconductor companies.

  2. II-VI Incorporated: Another major player, II-VI has been involved in significant deals such as a $100 million agreement to supply SiC wafers to China for electric vehicle chips.

  3. Xiamen Powerway Advanced Material Co. Ltd: This company is among the noted suppliers in the SiC wafer market.

  4. STMicroelectronics (Norstel AB): STMicroelectronics, through its subsidiary Norstel AB, is a significant player in this market.

  5. Showa Denko KK: Based in Japan, Showa Denko KK is another key supplier in the SiC wafer market.

Additionally, Chinese companies like SICC, TankeBlue, and San’an have significantly increased their production capacity and are expected to control a substantial portion of the market. For instance, it is anticipated that more than half of the world’s SiC wafers might come from China by 2024, with companies like SICC and TankeBlue jointly controlling about 5% of the global market. This increase in production is a result of the substantial rise in production by local manufacturers and collaborations with major companies like Bosch, Infineon, and STMicroelectronics.

Infineon Technologies AG has also been diversifying its SiC material supplier base. They have signed an agreement with SICC to supply 150-millimeter wafers and boules for the manufacturing of SiC semiconductors. Infineon is expanding its manufacturing capacities in Malaysia and Austria to meet the growing SiC demand.

These companies are focusing on expanding their customer base across foreign countries and leveraging strategic collaborative actions to improve their market percentage and enhance profitability

Common University Research that uses Silicon Carbide Wafers?

Silicon carbide (SiC) wafers are being actively used in university research for a variety of innovative applications:

  1. University of Arkansas: They have received over million in grants to build and operate a national SiC research and fabrication facility. This new center will concentrate on advancing silicon carbide-based chips, essential for gear that must endure intense heat and ideal for defense use as well as tough industry roles like powering cars or exploring the high-heat realms of Earth's inner layers and outer space.

  2. University of Illinois Urbana-Champaign: Researchers here have been working on understanding the thermal conductivity of cubic silicon carbide (3C-SiC) bulk crystals. Exploration into 3C-SiC crystals has uncovered that their proficiency in transferring heat is nearly unparalleled, with only diamond exceeding them. The discovery that 3C-SiC can move heat almost as well as diamond might be a game-changer for keeping power electronics cool, especially when they have to deal with intense bursts of heat.

  3. National Renewable Energy Laboratory (NREL): They are partnering with industry and academia to improve the materials and processes used to manufacture SiC wafers. They're tackling tough issues with SiC creation, like the tricky problem of basal plane dislocations popping up while they make it, which can mess up how well those fancy SiC switches in electronics work.

These research efforts underscore SiC's escalating role in cutting-edge chip tech, promising to revolutionize diverse sectors with its standout qualities.
