Diamond Chip or carbon Chip is an electronic chip manufactured on a Diamond structural Carbon wafer. OR it can be also defined as the electronic component manufactured using carbon as the wafer. The major component using carbon is (cnt) Carbon Nanotube. Carbon Nanotube is a nano-dimensional made by using carbon. It has many unique properties. [1]

Figure 1. The Diamond Chip Technology

Figure 1 shows diamond Chips are manufactured Diamond structural Carbon wafer. Diamond chip are also called carbon chip. Major component in these Diamond Chip are carbon nanotube which were discovered in 1991. Although structure of carbon is non-conducting in nature. So we have to perform the doping method to fulfill our requirement. We use nitrogen as the n-type doping agent and boron as p-type doping agent. They are made of several concentric walls arranged in hexagonal pattern. However, as compared to that of silicon as it is very tough to diffuse due to strong attraction of diamond atoms. It is assumed that diamond chip can transit power at rate of 100GHz. [2]

Advantages Of Diamond Chip

1. Smaller Components Are Possible

As the size of the carbon atom is small compared with that of silicon atom, it is possible to etch very smaller lines through diamond structural carbon. We can realize a transistor whose size is one in hundredth of silicon transistor.

2. It Works At Higher Temperature

Diamond is very strongly bonded material. It can withstand higher temperatures compared with that of silicon. At very high temperature, crystal structure of the silicon will collapse. But diamond chip can function well in these elevated temperatures. Diamond is very good conductor of heat. So if there is any heat dissipation inside the chip, heat will very quickly transferred to the heat sink or other cooling mechanics.

3. Faster Than Silicon Chip

Carbon chip works faster than silicon chip. Mobility of the electrons inside the doped diamond structural carbon is higher than that of in he silicon structure. As the size of the silicon is higher than that of carbon, the chance of collision of electrons with larger silicon atoms increases. But the carbon atom size is small, so the chance of collision decreases. So the mobility of the charge carriers is higher in doped diamond structural carbon compared with that of silicon.

4. Larger Power Handling Capacity

For power electronics application silicon is used, but it has many disadvantages such as bulk in size, slow operating speed, less efficiency, lower band gap etc at very high voltages silicon structure will collapse. Diamond has a strongly bonded crystal structure. So carbon chip can work under high power environment. It is assumed that a carbon transistor will deliver one watt of power at rate of 100 GHZ. Now days in all power electronic circuits, we are using certain circuits like relays, or MOSFET inter connection circuits (inverter circuits) for the purpose of interconnecting a low power control circuit with a high power circuit.
