Due to limitations in the production volume and cost of natural diamond, industrial-grade diamond is primarily produced by utilizing… Diamond deposition equipment It is produced through artificial synthesis. In its early stages, synthetic diamond was primarily used in traditional industrial applications such as cutting, grinding, and drilling. As technology advanced, attention shifted to its other outstanding properties beyond mechanical performance, prompting research into new application areas. Today, diamond has garnered significant interest in cutting-edge fields like quantum communication and computing, optical windows, and semiconductors. Moreover, by leveraging… Diamond deposition equipment Producing large‑size, high‑purity, high‑quality, and dopable single‑crystal diamonds is a prerequisite for their large‑scale application in the aforementioned fields.
Microwave plasma chemical vapor deposition (MPCVD) is currently the leading method for synthesizing high-quality diamond with broad applications across multiple fields, owing to its distinct advantages in producing large‑size, high‑quality diamonds.
During the MPCVD process for single-crystal epitaxial growth, the growth surface gradually shrinks, which limits the fabrication of large‑size single‑crystal diamonds. To increase the crystal size, the main approaches currently employed include mosaic stitching on homoepitaxial substrates, lateral epitaxial growth on heteroepitaxial substrates, repeated stitching, and three‑dimensional growth. However, the preparation of large‑size single‑crystal diamonds using these methods still faces numerous challenges that require resolution, leveraging… Diamond deposition equipment The MPCVD process for fabricating large‑size, high‑quality diamond still has considerable room for improvement.
