4 inch SiC Substrate P Grade

Where can purchase 4 inch SiC Substrate(P grade)? You can contact HMT-professional 4 inch SiC Substrate Manufacturer in China. We offer P grade (350um) Conductive N type and SI type of 4” SiC Substrate with preferential prices. Although the mainstream of SiC is now 6 inch, 8 inch, and even 12 inch have been successfully developed. we still keep 4 inch SiC Substrate and 4 inch SiC Boules(P grade) for some customers.

· Semi-insulating SiC substrates: Primarily used in RF devices and related fields.

· Conductive SiC substrates: Mainly employed in power devices, representing a key focus of the company’s development in recent years. They are applied in critical electric drive and control components of new energy vehicles, including main drive inverters, OBCs, DC/DC converters, and off-board charging piles.

4 inch SiC Substrate VS 6 inch SiC Substrate

SiC substrates serve as the “foundation” for manufacturing high-performance chips. As a core upstream material in the industrial chain, they are widely used in high-power and high-frequency applications such as new energy vehicles, charging piles, 5G base stations, high-speed rail, and wind power.

Compared to traditional silicon materials, SiC offers high temperature resistance, high voltage tolerance, and superior electrical conductivity. Chips manufactured with SiC are smaller, more energy-efficient, and deliver higher performance, making them the mainstream choice for high-end power devices.

Initially, SiC substrates were primarily used in electric vehicles (particularly in 800V high-voltage platforms). To meet the growing demand for high-power, high-performance AI computing. They are now increasingly adopted in the AC/DC conversion stage of power supply units in AI data centers. This helps reduce energy consumption, improve thermal management solutions, and enhance server power density.
