Chemical vapor deposited (CVD) diamond is polycrystalline film grown in a metastable state at low pressure. Today's quality of CVD diamond components makes it possible to use them in a wide range of applications such as heat spreaders, high power laser windows, domes for IR imaging in adverse environments, etc. CVD diamond measures up to natural and synthetic diamonds, as it possesses the same great hardness, good wear resistance, excellent thermal conductivity, electric isolation and chemical stability at high pressures and high temperatures. The appeal of CVD diamond is that it can be fabricated into large and affordable components, therefore making high quality diamond available to the industry. The CVD diamond film is known as an ideal "heat sink" material to be used in many types of electronic devices: laser diodes with high current density and high power density, microwave power devices, large scale IC and semiconductor's refrigerator, etc. This material has a much higher thermal conductivity and a lower thermal expansion then that of many of well-known thermal conductors (e.g. copper). This makes CVD diamond film well matched up to most electronic materials. CVD diamond has good prospects in a diverse range of new applications such as laser communication, electronic and computer industries, military weaponry and space technology.
