CONCLUSIONCONCLUSION

Carbon is more advantages than Silicon. By using Carbon is more advantages than Silicon. By using carbon as the manufacturing material, we can achieve carbon as the manufacturing material, we can achieve smaller, faster and stronger chips. Thus diamond chip smaller, faster and stronger chips. Thus diamond chip replaces the need of silicon in every aspect in future replaces the need of silicon in every aspect in future generation.generation.
