Thermal Management

Use the ultra high thermal conductivity of diamond
for temperature critical packages

Higher power in smaller devices, and the integration of these to
other devices present heat dissipation challenges. High thermal
heat flux significantly impacts performance and reliability. The unsurpassed thermal conductivity of diamond and its high electrical resistivity, allow for increased microprocessor frequency, higher
output power, smaller parts and longer lifetimes.

Diamond has thermal conductivity five times that of copper and is
an electrical insulator, making for a perfect heat sink. CVD Diamond has all of the properties of single crystal diamond without many of
the size and shape limitations.

CVD Diamond is being used in the following applications:

• RF Power Devices
• Power Semiconductors
• High Speed Processors
• Radar Amplifiers
• High powered laser diode arrays
• LEDs
• Multi chip power module packages
• Flip chip

Diamond also has a low density for lighter weight applications of aircraft and space craft electronic systems, notebook computers
and other mobile devices.
