AKHAN Technologies reports diamond microelectronics breakthrough

November 15, 2011 — AKHAN Technologies, advanced diamond electron device design company, is commercializing diamond microelectronics with a shallow n-type diamond material over silicon.

The Miraj Diamond platform process creates n-type diamond material over silicon with previously undemonstrated characteristics, such as shallow ionization energy of 250meV, high carrier mobility (greater than 1000 cm2/Vs in nanocrystalline diamond thin films), no graphitic phases, and 900A/mm2 current density at +2V forward bias in low-voltage/high-current diode device applications.

AKHAN Technologies claims that the diamond material shows the shallowest ionization energy, highest current density, fastest electron mobility, and highest power handling capability seen in diamond, specifically n-type diamond.

The AKHAN Miraj Diamond platform features shallow n-type diamond and n-type ohmic contact, electronically outperforming any n-type semiconductor diamond at any applied voltage, while retaining mirror-like smoothness (see image above), with films often smoother at the end of processing than at the beginning.

Microchips fabricated from the AKHAN Miraj Diamond platform boast higher speeds (1841cm2/Vs versus <1400 cm2/Vs for electron mobility and 1000 cm2/Vs versus <450 cm2/Vs for hole mobility), with increased power handling capability (75W/mm demonstrated [DC] in low field), without overheating (600
