Recently, three Chinese companies have made significant progress in the 12-inch SiC technology field, injecting strong impetus into the independent and controllable development of China's semiconductor industry.

I. Zhejiang Jingrui SuperSiC: Successful Development of 12-inch Conductive SiC Crystals

Core Breakthrough:

Successfully grown the first 12-inch conductive silicon carbide (SiC) single crystal, with a diameter of 309mm and excellent quality.

Based on independently developed SiC single crystal growth furnace and crystal growth technology, overcoming challenges such as uneven temperature fields and crystal cracking.

Technical Highlights

1. Process Innovation:

Optimized temperature field design and gas phase material distribution process, realizing independent and controllable full-size crystal growth technology from 6 to 12 inches.

Process iteration covers 8-12 inches, improving crystal yield and consistency.

2. Industrial Impact:

Reducing chip manufacturing costs and accelerating the localization of the SiC industry chain.

Promoting large-scale applications in electric vehicles, new energy, and 5G.

III. Shandong Likuan Microelectronics Equipment: Accelerated Commercialization of 12-inch SiC Crystal Growth Equipment

Core Breakthrough:

Completed the research and development of a 12-inch PVT resistance heating crystal growth furnace, with the first batch of two devices delivered.

Accelerating the development of 12-inch liquid-phase crystal growth equipment, planning for mass production in 2025.

Technical Highlights

1. Equipment Advantages:

Independent intellectual property rights hot field design, temperature uniformity improved by over 30%.

Automated control system reduces manual intervention, significantly improving cost competitiveness.

2. Market Layout:

8-inch PVT crystal growth furnaces have been adopted by leading domestic and international customers.

The goal is to promote domestic SiC materials into the first echelon of the global supply chain.

Summary

The breakthroughs of three Chinese companies in the 12-inch SiC field mark the transition of domestic semiconductor technology from "catching up" to "leading". The collaborative innovation of the material end (Jingrui, Nansha) and the equipment end (Likuan) not only reduces the cost of SiC chips but also helps upgrade strategic industries such as new energy vehicles, photovoltaics, and rail transit. 2025 may become the first year of large-scale application of domestic SiC.
