Silicon carbide substrates have many defects and cannot be processed directly. A specific single crystal thin film needs to be grown on them through an epitaxial process to make chip wafers. This thin film is the epitaxial layer. Almost all silicon carbide devices are realized on epitaxial materials. High-quality silicon carbide homogeneous epitaxial materials are the basis for the development of silicon carbide devices. The performance of epitaxial materials directly determines the realization of the performance of silicon carbide devices.

This blog takes "What is the epitaxial process?" as its theme, and provides a detailed analysis from the dimensions of Overview of Epitaxial Processes, Types of Epitaxy, Factors Influencing the Epi Process, Epitaxial Growth Techniques, EPI Growth Modes, and Epitaxy Growth’s Importance.

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.

The main difference between epitaxy and atomic layer deposition (ALD) lies in their film growth mechanisms and operating conditions. Epitaxy refers to the process of growing a crystalline thin film on a crystalline substrate with a specific orientation relationship, maintaining the same or similar crystal structure. In contrast, ALD is a deposition technique that involves exposing a substrate to different chemical precursors in sequence to form a thin film one atomic layer at a time.

This article describes the physical parameters and product characteristics of VeTek Semiconductor's Porous Graphite, as well as its specific applications in semiconductor processing.

SiC has high hardness, thermal conductivity, and corrosion resistance, making it ideal for semiconductor manufacturing. CVD SiC coating is created through chemical vapor deposition, providing high thermal conductivity, chemical stability, and a matching lattice constant for epitaxial growth. Its low thermal expansion and high hardness ensure durability and precision, making it essential in applications like wafer carriers, preheating rings, and more. VeTek Semiconductor specializes in custom SiC coatings for diverse industry needs.
