CVD diamond

Product overview

CVD diamond, chemical vapor deposition diamond (also known as CVD diamond film), is another significant revolution in the field of synthetic diamond after high temperature and high pressure diamond. The size can be very large, and the product specifications that can be mass-produced have reached 120MM in diameter and 2MM in thickness, and the crystalline quality can be comparable to natural LLA diamond. CVD diamond is under the condition of low pressure, CH4, C3H8 and other carbon-containing gases by high temperature decomposition.

CVD Diamond High power semiconductor thermal management solution

The thermal properties of diamond are shown in the extremely high thermal conductivity of diamond, its thermal conductivity at room temperature is 1000~2000w/m.k, which is 3~5 times that of copper materials, much higher than the thermal conductivity of aluminum nitnitide, Cu-W alloy, alumina, beryllium oxide and other materials currently used, second only to natural lla type and Ib high-quality single crystal synthesized under high pressure. And the coefficient of thermal expansion is very small, but also a very good insulating material, therefore, CVD diamond is currently in high power semiconductor thermal management has an irreplaceable advantage, high power laser diode and MCMs(multi-chip three-dimensional assembly technology) is the current CVD diamond film thermal application of the two main application areas.

CVD diamond use

Used in single-point diamond dressing tools, multi-point diamond dressing tools, diamond dressing rollers; Used for dressing brown corundum and silicon carbide grinding wheels, diamond grinding wheels and CBN ceramic bond grinding wheels.
