Vetek Semiconductor participated in CSEAC 2026 in Wuxi, China, showcasing its advanced CVD SiC and TaC coatings, graphite components, SiC ceramics and other semiconductor core materials. The event provided valuable opportunities to strengthen customer partnerships, discuss new technologies, advance cooperation projects and explore future opportunities across the global semiconductor industry.

Over the past few years, the center stage of packaging technology has gradually been ceded to a seemingly "old technology" - CMP (Chemical Mechanical Polishing). When Hybrid Bonding becomes the leading role of the new generation of advanced packaging, CMP is gradually moving from behind the scenes to the spotlight.

Explore how CVD SiC coating is used in semiconductor processes, including its structure, performance characteristics, and typical applications, along with its relevance in high-temperature applications.

Quartz devices play a critical role in solar cell manufacturing, offering exceptional thermal resistance, chemical purity, and structural stability required in high-temperature processes. From quartz diffusion tubes and crucibles to quartz boats and furnace components, these high-purity materials are essential for achieving optimal efficiency in diffusion, CVD, and wet etching steps.

CVD silicon carbide coating is produced by depositing a dense SiC layer onto high-purity graphite through controlled gas-phase and surface reactions. This article explains substrate preparation, MTS-based CVD growth, nucleation and mass transfer, coating thickness and uniformity, SiC/graphite interface stress, common defects and semiconductor-grade inspection. It also shows why process parameters and component geometry must be engineered together for susceptors and wafer carriers used in epitaxy and MOCVD.

In modern chip manufacturing, the substrate provides physical support and a heat dissipation path, while the epitaxial layer determines the electrical performance limits of the device. This article provides an in-depth analysis of the fundamental differences between single-crystal silicon and silicon carbide substrates and CVD/MBE epitaxial processes, and reveals how epitaxial technology enhances the performance of high-frequency and high-voltage devices by reducing defect density and incorporating strain engineering. Whether you are a process engineer or a procurement decision-maker, this guide will help you quickly identify the most suitable wafer selection strategy.
