The global semiconductor industry's pursuit of wider bandgap materials has positioned Silicon Carbide (SiC) as a cornerstone for next-generation power electronics. Leading 4 inch SiC Substrates Manufacturers are at the forefront of this supply chain, which is fundamentally built upon several critical segments: substrate → epitaxial wafer → device fabrication (chips & modules) → end-use applications.

NVIDIA, TSMC, and other industry giants plan to adopt silicon carbide (SiC) substrates for the interposer layer in GPU advanced packaging, replacing traditional si materials. HMT can supply 6inch 8inch and 12inch SiC Substrate Wafer with 4H-N and 4H-SI type.

HMT is a leading SiC wafer manufacturer, providing high quality 2 inch, 4 inch, 6 inch, and 8 inch SiC as-cut wafers and SiC boules for laser slicing testing. With the widespread application of SiC materials in the semiconductor industry, particularly in electric vehicles, renewable energy, and power electronics, the demand for high-performance SiC wafers continues to grow.

SiC and GaN are called "wide-band gap semiconductors" (WBG). Due to the production process used, WBG equipment shows the following advantages:

Epitaxial layer is based on wafer, through epitaxial process to grow a specific single crystal film, substrate wafer and epitaxial film together called epitaxial sheet. The SiC Epitaxial layer is grown on the conductive SiC substrate to prepare the SiC homogeneous epitaxial sheet, which can be further made into Schottky diodes, MOSFETs, IGBTs and other power devices, among which 4H-SiC substrate is the most used.

In recent years, SiC substrate manufacturers have accelerated the mass production progress of 8 inch SiC substrate, and at last year, the industry leader Wolfspeed has launched the world's first 8-inch SiC wafer fab, which also means that 8 inch substrates officially opened the mass production curtain.

SiC material has wide band gap, high breakdown electric field, high thermal conductivity, high electron mobility and radiation resistance, SiC based SBD and MOSFETs are more suitable for high frequency, high temperature, high pressure, high power and radiation resistance environment. With the same power level, the SiC device can meet the requirements of higher power density and more compact design.

SiC industry chain is mainly composed of single crystal substrate, epitaxy, devices, manufacturing and testing links. HMT offer the best price of 4 inch and 6 inch SiC ingots and SiC wafer with high quanlity.we also support customzied SiC ingots and substrate upon your requirements.

Recently, Toyota announced that it will launch a new bZ4X SUV battery electric vehicle in May this year. According to Toyota Industrial Corporation's announcement on April 13, the bZ4X uses its in-car charging device ESU, which integrates an in-car charger with SiC technology and a DC-DC converter.
