INTRODUCTION

Electronics without silicon is unbelievable, but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip's. It has many disadvantages when it is used in power electronic applications, such as bulk in size, slow operating speed etc. Carbon, Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors in normal temperature. So in the earlier days they are used widely for the manufacturing of electronic components. But later it is found that Germanium has many disadvantages compared to silicon, such as large reverse current, less stability towards temperature etc so in the industry focused in developing electronic components using silicon wafers. Now research people found that Carbon is more advantages than Silicon. By using carbon as the manufacturing material, we can achieve smaller, faster and stronger chips. They are succeeded in making smaller prototypes of Carbon chip. They invented a major component using carbon that is CARBON NANOTUBE, which is widely used in most modern microprocessors and it will be a major component in the coming era. Crystalline diamond film that could produce more resilient semiconductor chips than those made from silicon. Until now, synthetic diamonds have proved a poor semiconducting material. Their microscopic crystals are a disorderly hodgepodge, and their edges are not evenly aligned, impeding the flow of current. Now, Schreck and his colleagues have discovered that by growing the diamond film on a surface of iridium, instead of on silicon, they can keep its grain boundaries aligned. Adding atoms of boron or nitrogen enables the diamond film to conduct electricity. Manufacturers plan to build a diamond chip that can withstand temperatures of 500 C, compared to only about 150 C for silicon chips. The chips would be most useful in devices located near hot-burning engines, such as those used in automobiles or airplanes

DIAMOND CHIP

Single definition, 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.

HOW IS IT POSSIBLE?

Pure Diamond structural carbon is non-conducting in nature. In order to make it conducting we have to perform doping process. We are using Boron as the p-type doping Agent and the Nitrogen as the n-type doping agent. The doping process is similar to that in the case of Silicon chip manufacturing. But this process will take more time compared with that of silicon because it is very difficult to diffuse through strongly bonded diamond structure. CNT (Carbon Nanotube) is already a semi conductor.

A crystalline diamond film that could produce more resilient semiconductor chips than those made from silicon, commonly synthetic diamonds have proved a poor semi conducting material. Their microscopic crystals are a disorderly hodgepodge, and their edges are not evenly aligned, impeding the flow of current. Now but by growing the diamond film on a surface of iridium, instead of on silicon, they can keep its grain boundaries aligned. Adding atoms of boron or nitrogen enables the diamond film to conduct electricity. Manufacturers plan to build a diamond chip that can withstand temperatures of 500 C, compared to only about 150 C for silicon chips. The chips would be most useful in devices located near hot-burning engines, such as those used in automobiles or airplanes. Diamond has an extremely high thermal conductivity, can withstand high electric fields, and can be made into a...
