The large growth in the information technology and information technology industry depends on VLSI circuits with increasing functionality and performance at minimum cost and power dissipation, and 2D integrated circuits generate multiple gate delays and Delay of interconnection. Therefore, to reduce these delays and total energy consumption, 3D IC technology is introduced.
Many companies such as MIT (USA), IBM are doing research on 3D IC technology and are going to introduce cheaper chips for certain applications, such as the memory used in digital cameras, cell phones, handheld devices, etc. The original cost will be 10 times lower than the current cost.
