SHJ CARBON At SEMICON China 2026: Meet Us At Booth E6-6469-2

SHJ CARBON has worked with graphite and carbon materials for more than 25 years.

We started in 2001. In 2006, we invested in a graphite electrode factory and partnered with Tokai Carbon, one of the world's leading carbon companies. That partnership grew. Today we manage Tokai's specialty carbon business for the Chinese market.

We've since built relationships with other global leaders. Kyocera named us their semiconductor division distributor for precision ceramics in China. Temnest appointed us exclusive distributor for polishing and grinding materials. Dow and DuPont work with us on advanced materials for semiconductor applications.

This network means we access the best raw materials and processing technologies. We combine that with local support and technical expertise.

Our graphite solutions support semiconductor manufacturing across multiple processes:

Single Crystal Silicon Growth

Most silicon wafers start as single crystals pulled from molten silicon. The Czochralski process relies on graphite components-crucibles, heaters, insulation shields, and lift mechanisms. These parts must maintain structural integrity above 1400°C while resisting silicon vapor attack.

Our high-density graphite grades provide the thermal stability and purity required for defect-free crystal growth. The isotropic structure ensures uniform heat distribution, reducing thermal stress in growing crystals.

Silicon Carbide Crystal Growth

SiC presents bigger challenges. PVT furnaces operate above 2000°C. Graphite crucibles and insulation directly influence crystal quality.

Research shows that graphite structure affects carbon transport, temperature gradients, and polytype stability. Some growers use porous graphite inserts to maintain 4H-SiC rather than unwanted polytypes.

SHJ CARBON understands these complexities. We work with SiC growers to select graphite grades that balance purity, density, and carbon transport characteristics for their specific process.

MOCVD and Epitaxial Growth

MOCVD systems use graphite susceptors to hold wafers during epitaxial growth. These susceptors must maintain flatness through thousands of thermal cycles while resisting coating buildup.

Our graphite susceptors feature tight dimensional tolerances and smooth surface finishes. The isotropic structure prevents warping, while high purity minimizes contamination during sensitive layer deposition.

Ion Implantation and Etching

Beyond crystal growth, graphite components appear throughout wafer processing. Ion implanters use graphite parts to handle high-energy beams. Etching chambers rely on graphite for chemical resistance and electrical properties.

For these applications, SHJ CARBON provides custom-machined components meeting exact specifications.

The semiconductor industry keeps evolving. Several trends shape where graphite materials head next.

Third-generation semiconductors continue gaining ground in power devices, RF applications, and electric vehicles. SiC and GaN require even higher purity graphite and more sophisticated thermal field designs. Industry projections suggest graphite demand from this sector will grow substantially through 2032.

8-inch SiC transition pushes toward larger substrates. This shift demands bigger graphite components with tighter property uniformity. Crucibles and susceptors for 200mm SiC require exceptional dimensional stability.

Higher purity standards emerge as devices shrink. We continue advancing our purification capabilities to meet future specifications.

Supply chain diversification remains a priority. Many semiconductor manufacturers now seek qualified alternative sources for critical materials. SHJ CARBON provides that option-reliable quality with responsive local support.

Here's what sets us apart.

We know graphite. Twenty-five years working with this material. We understand how it behaves at extreme temperatures, how different grades perform, and what works in specific applications.

We work with global leaders. Tokai Carbon, Kyocera, Temnest-these companies chose SHJ as their partner. That matters.

We provide solutions, not just materials. Tell us about your process. We'll recommend the right graphite grade and configuration. Not based on what's most expensive-based on what works best for you.

We're local and responsive. Based in China with a Shanghai office, we respond quickly to questions and deliver reliably.

See You in Shanghai
