Avinash Gautam presents information on diamond chips. Diamond can be made into a semiconductor through doping, which is difficult. The first diamond chip was developed by NTT in Japan, operating at 81GHz, over twice as fast as earlier silicon chips. Diamond chips can withstand higher temperatures than silicon and resist higher voltages, allowing for smaller, faster components. However, diamond chips are very expensive to produce and doping diamond is challenging. Potential applications include microcontrollers, computers, automobiles, and devices near hot engines.

2. SOME FACTS…
 Carbon is not a semiconductor.
 Some of the carbon allotropes can acts as
semiconductors

3. What is a Diamond chip ?
 Diamond or carbon chip is electronic chip
manufactured on structure carbon wafer.
 It can also be defined as an electronic chip
manufactured using carbon as the wafer.

4. Properties of Diamond :
 Diamond is allotrope of carbon and it is the hardest
material in nature.
 It has small toughness.
 It is a good electrical insulator , but good thermal
conductor

5. Diamond As a Semiconductor :
 Diamond is a insulator ,but it can be made conducting by
doping it with certain elements.
 Boron p –type doping element.
 Nitrogen n-type doping element.
 After doping diamond can act like a semiconductor.
 But this process is very
difficult and Time
consuming.

6. Invention of Diamond Chip :
 A diamond semiconductor operates on 81 GHz frequency ,and
it is more then twice speed of earlier devices.
 Developed by the NIPPON TELEGRAPH and TELEPHONE
CORPORATION (NIT), Japan.

7. Properties of Diamond Chip :
 Diamond chip can withstand a temperature of 500 degree
Celsius , but 150 degree Celsius for silicon chip.
 It can operate on 81GHz frequency.
 Can resist voltages up to 200V , where as 20V for silicon.

8. Advantages :
 Smaller components are possible.
 It works at higher temperature.
 Faster than silicon chip.
 Large power carrying capacity

9. Smaller Components are Possible :
 As the size is smaller – it is possible to cut very smaller lines
through diamond structural carbon.
 We can imagine a transistor whose size is one hundredth of
silicon transistor .

10. Faster Than Silicon Chip :
 Mobility of the electrons inside the doped diamond structure
carbon is higher than that of in the silicon structure.
 As the size of the silicon is higher than that of carbon , the
chance of the collision of electrons , with large silicon aroms
increases as compared to carbon chip.

11. Disadvantages :
 Very expensive than silicon.
 Electricity can not flow smoothly through diamond .
 Doping of diamond is very difficult .

12. Applications :
 In microcontrollers.
 Smaller , speedier computer chips can be made using
diamond chips.
 In automobiles and in airoplanes.
 The chip would be most useful in devices located near hot
burning engines .

13. Conclusions :
 The diamond chip replaces the need of all silicon
chip in every aspect in future generations…
