In the semiconductor manufacturing industry, as device size continues to shrink, the deposition technology of thin film materials has posed unprecedented challenges. Atomic Layer Deposition (ALD), as a thin film deposition technology that can achieve precise control at the atomic level, has become an indispensable part of semiconductor manufacturing. This article aims to introduce the process flow and principles of ALD to help understand its important role in advanced chip manufacturing.

Silicon carbide nanomaterials (SiC) are materials with at least one dimension at the nanometer scale (1-100nm). These materials can be zero-, one-, two-, or three-dimensional and have diverse applications.

CVD SiC is a high-purity silicon carbide material manufactured by chemical vapor deposition. It is mainly used for various components and coatings in semiconductor processing equipment. The following content is an introduction to the product classification and core functions of CVD SiC

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.

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.
