Global Silicon Carbide (SiC) Ingot market size was valued at USD 325.8 million in 2023. The market is projected to grow from USD 412.5 million in 2024 to USD 1,086.2 million by 2030, exhibiting a CAGR of 17.5% during the forecast period.

Silicon Carbide Ingots are high-purity crystalline materials produced through specialized growth processes like physical vapor transport (PVT). These ingots form the foundation for SiC wafers used in power electronics, RF devices, and optoelectronic applications. The material’s wide bandgap, high thermal conductivity, and extreme durability make it indispensable for next-generation semiconductor applications.

The SiC ingot market represents a critical link in the semiconductor supply chain, where material quality directly impacts device performance. Market growth is being driven by several factors including:
– The rapid adoption of electric vehicles requiring high-efficiency power electronics
– Expansion of 5G infrastructure needing robust RF components
– Government investments in advanced semiconductor manufacturing capabilities

Segmentation by Product Type

The SiC ingot market can be divided into two primary product categories based on electrical properties:

1. N-type Silicon Carbide Ingots

N-type ingots contain donor impurities that create excess electrons, making them ideal for power electronic applications where high electron mobility is required. These represent the majority share of the current market.

• Market Insight: This segment holds approximately 72% market share (2023) due to widespread use in power devices. The superior conduction properties of N-type SiC make it particularly valuable for MOSFETs and Schottky diodes in electric vehicle inverters.

• Trend: A recent shift toward higher-quality N-type ingots (lower defect densities) is emerging as device manufacturers push operational voltage limits beyond 1700V.

2. Semi-insulating Silicon Carbide Ingots

Semi-insulating ingots feature extremely high resistivity, making them perfect for RF and microwave applications where minimal signal loss is crucial.

• Market Insight: While smaller in volume compared to N-type, this segment commands premium pricing due to stringent quality requirements. The 5G revolution is creating strong demand for semi-insulating substrates in RF filters and power amplifiers.

• Trend: Leading manufacturers are focusing on reducing micro-pipe defects and improving crystal uniformity to meet the growing needs of defense and telecom sectors.

Segmentation by Application

SiC ingots serve as the raw material for two critical semiconductor components:

1. Substrate Manufacturing

The largest application segment where ingots are sliced and polished into wafers for epitaxial growth or device fabrication.

• Insight: Substrate applications account for about 65% of ingot consumption. The quality of substrates directly impacts the performance of final semiconductor devices.

• Trend: There’s growing demand for larger diameter substrates (transition from 150mm to 200mm) to improve manufacturing economies in power electronics.

2. Epitaxial Wafer Production

High-quality ingots are used to produce epitaxial wafers with precisely controlled crystal structures for specialized semiconductor devices.

• Insight: This segment is growing at a faster rate (over 19% CAGR) as more SiC devices require custom epitaxial layers. The automotive industry’s shift to 800V systems is particularly driving this demand.

• Trend: Epitaxial wafer manufacturers are increasingly demanding ingots with specific off-axis orientations to optimize device performance.

Segmentation by End-User

Five major industry groups account for nearly all SiC ingot consumption:

1. Power Electronics Manufacturers

The dominant end-user sector for SiC materials, particularly for EV components, industrial converters, and renewable energy systems.

• Insight: Major automotive suppliers and power module manufacturers are securing long-term ingot supply agreements to ensure stable production.

• Trend: Production localization trends are emerging as regions build out domestic SiC supply chains for strategic industries.

2. RF Component Producers

RF semiconductor companies specializing in 5G infrastructure and defense applications rely on high-quality semi-insulating substrates.

• Insight: This segment drives some of the most stringent quality requirements in the industry, resulting in higher ASPs for qualifying ingots.

• Trend: Millimeter-wave 5G deployments are pushing the need for even lower defect densities in SiC materials.

3. LED and Optoelectronics Industry

While a smaller segment, certain specialized optoelectronic applications use SiC ingots as substrates.

• Insight: The market is relatively mature but maintains stable demand for niche applications like UV LEDs and specialized sensors.

• Trend: Some manufacturers are exploring hybrid SiC/Si substrates to balance performance and cost.

4. Foundry Service Providers

Semiconductor foundries offering SiC fabrication services have become significant ingot consumers.

• Insight: As more companies adopt fab-lite strategies, foundries are expanding SiC capacity, creating additional demand pull.

• Trend: Leading foundries are developing proprietary process technologies that influence ingot specification requirements.

5. Research Institutions

Universities and government labs conducting advanced semiconductor research represent a consistent though smaller segment.

• Insight: While not significant in volume terms, research institutions often pioneer new applications that later drive commercial demand.

• Trend: Increased government funding for wide-bandgap semiconductor research is supporting this segment.
