In PECVD production, many coating and deposition problems do not start with plasma power or gas chemistry. They start with the carrier that holds the wafers.

Alumina ceramics are the "workhorse" for manufacturing ceramic components. They exhibit excellent mechanical properties, ultra-high melting points and hardness, corrosion resistance, strong chemical stability, high resistivity, and superior electrical insulation. They are commonly used to fabricate polishing plates, vacuum chucks, ceramic arms, and similar parts.

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.

Hot pressing sintering is the main method for preparing high-performance SiC ceramics. The process of hot pressing sintering includes: selecting high-purity SiC powder, pressing and molding under high temperature and high pressure, and then sintering. SiC ceramics prepared by this method have the advantages of high purity and high density, and are widely used in grinding discs and heat treatment equipment for wafer processing.

Single crystal materials alone cannot meet the needs of the growing production of various semiconductor devices. At the end of 1959, a thin layer of single crystal material growth technology - epitaxial growth was developed.

Tantalum carbide (TaC) coating can significantly extend the life of graphite parts by improving high temperature resistance, corrosion resistance, mechanical properties and thermal management capabilities. Its high purity characteristics reduce impurity contamination, improve crystal growth quality, and enhance energy efficiency. It is suitable for semiconductor manufacturing and crystal growth applications in high-temperature, highly corrosive environments.
