Graphite Boat, stands at the forefront of technological innovation in its industry, featuring a suite of groundbreaking advancements designed to enhance performance, purity, and lifespan. Below, we delve into the core technologies that define graphite boat's excellence:

Tantalum carbide coating is an important high-strength, corrosion-resistant and chemically stable high-temperature structural material with a melting point of up to 4273 °C, one of the several compounds with the highest temperature resistance. It has excellent high-temperature mechanical properties, resistance to high-speed airflow scouring, ablation resistance, and good chemical and mechanical compatibility with graphite and carbon/carbon composites. Therefore, in the epitaxial process of GaN LEDs and SiC power devices such as MOCVD, TaC coating has excellent acid and alkali resistance to H2, HCl, NH3, which can completely protect the graphite substrate material and purify the growth environment.

Doping involves introducing a dose of impurities into semiconductor materials to alter their electrical properties. Diffusion and ion implantation are two methods of doping. Early impurity doping was primarily accomplished through high-temperature diffusion.

The push for higher power density and efficiency has become a primary driver of innovation across multiple industries, including data centers, renewable energy, consumer electronics, electric vehicles, and autonomous driving technologies. In the realm of wide bandgap (WBG) materials, Gallium Nitride (GaN) and Silicon Carbide (SiC) are currently the two core platforms, viewed as pivotal tools leading power semiconductor innovation. These materials are profoundly transforming the power electronics industry to address the ever-increasing demand for power.

According to reports from German media, U.S. chip manufacturer Wolfspeed is pausing its plans to build a semiconductor plant in Germany.
