Huanghe Cyclone launches 3-inch CVD polycrystalline diamond film R&D project
Recently, Henan Huanghe Cyclone Co., Ltd. announced on its investor relations platform that Huanghe Cyclone will develop 3-inch diameter and optical-grade CVD polycrystalline diamond films , and plan to build a CVD polycrystalline diamond testing center to promote the application of CVD diamond films in thermal, optical, electrical, acoustic and electrochemical aspects.
CVD stands for Chemical Vapor Deposition. It is different from mining natural diamonds or synthesizing diamonds in a simulated high temperature and high pressure environment underground (HTHP method). The principle is to introduce carbon-containing gases (such as methane CH4) and hydrogen (H2) into a vacuum or low-pressure reaction chamber. Plasma is generated by excitation through a specific energy source (such as microwaves, hot wires, arcs, etc.), which decomposes the gas molecules. Under precisely controlled temperature (usually 800°C - 1200°C) and pressure, carbon atoms or carbon-containing groups are deposited, migrated, and arranged on the surface of a selected substrate (such as silicon wafers, molybdenum wafers, and even ceramics), eventually forming a diamond structure.
Single crystal vs. multi-crystalline
Single crystal diamond refers to the atoms arranged regularly and continuously throughout the crystal, just like a perfect crystal. It has excellent performance but is limited in size (especially large-sized single crystals are extremely difficult and slow to grow) and is extremely expensive.
Polycrystalline diamond film: It is composed of countless tiny diamond grains (usually in the nanometer to micrometer range) tightly stacked. There are grain boundaries between the grains. Although the grain boundaries will bring some minor differences in performance (such as slightly lower thermal conductivity and optical scattering), it solves the core bottleneck of single crystal diamond size and cost, making its large-scale and customizable production possible.
CVD polycrystalline diamond films combine the excellent properties of diamond (such as high hardness, high thermal conductivity, wide bandgap, etc.) and the designability of films (such as thickness, shape, adhesion substrate, etc.), and have important application value in many fields.
