Silicon Carbide (SiC) has firmly established itself as the core material for the third-generation semiconductor industry, essential for the rapid expansion of electric vehicles (EVs), renewable energy systems, and high-efficiency power electronics. To meet the skyrocketing demand and, crucially, to lower the overall cost of SiC devices, the industry is now aggressively pursuing a transition to larger wafer sizes.

The question is no longer if but when the 8-inch (200mm) 4H-N Type SiC substrate will displace the current 6-inch (150mm) standard.

Moving from 6-inch to 8-inch substrates increases the usable wafer area by approximately 78%. This larger area allows for a significantly higher number of chips per wafer, which is the primary driver for reducing the manufacturing cost per device. Since the cost of the substrate remains a major bottleneck for SiC adoption, the 8-inch wafer represents the most critical path to achieving cost parity with traditional silicon.

The specific combination, 4H-N Type, is the industry's focus because:

• 4H-SiC is the dominant crystal structure (polytype) for power devices, offering superior electron mobility and breakdown field strength.
• N-Type (electron-conductive) substrates are necessary for mainstream components like MOSFETs and Schottky diodes, which are ubiquitous in power applications.
• 
  

The Path to Mainstream Adoption

Industry leaders globally, including major US, European, and Chinese manufacturers, have confirmed that the 8-inch transition is a shared consensus, with many already building or ramping up 8-inch production lines. While 6-inch substrates remain the dominant player in the short term, 8-inch production is expected to move from the sampling stage to mass production and rapid adoption over the next 3-5 years. Eventually, it is projected to become the new industry standard, driving the next wave of growth in power semiconductors.
