Moore’s Law, named after Intel engineer Gordon Moore, has had a significant impact on the evolution of processors. It states that the number of transistors on a chip doubles approximately every two years, leading to increased computing capacity and lower costs. This has resulted in rapid technology advancements, fostering microprocessor innovation and driving the development of the semiconductor industry.
However, in recent years, the exponential growth predicted by Moore’s Law has slowed down, with processor speeds stagnating between 2 and 4 GHz. The challenge of fabricating smaller transistors has reached a limit, making it harder to manufacture. Nevertheless, Moore’s Law has guided chip makers in the development of faster CPUs, enabling advancements in technology.
The Challenges of Shrinking Transistors
As the evolution of processors continues, the fabrication of smaller transistors presents a significant challenge for chip manufacturers. The current method of fabricating these transistors, known as the photolithographic process, utilizes a 193 nm wavelength light to create chips with transistors as small as 14 nm. In fact, Intel has even implemented a 10 nm process on its 8th generation processors. However, as we approach the theoretical limits of transistor size, which is expected to be below 2 nm after 2021, new challenges arise.
The density of transistors on microchips creates higher temperatures, which poses a limitation on performance. Cooling down the transistors becomes increasingly difficult as they become smaller, making it harder to dissipate the heat generated. This limitation in temperature management affects the overall performance of the processors and the efficiency of the computing systems. Therefore, new techniques and architecture designs are required to overcome these challenges in microprocessor development.
Researchers and engineers are exploring alternative methods and materials to address the limitations of chip manufacturing. This includes investigating new chip fabrication processes, such as extreme ultraviolet lithography, which utilizes a shorter wavelength light to create even smaller transistors. Additionally, novel materials like graphene are being studied as potential alternatives to silicon-based CPUs. Graphene offers higher speeds and lower energy consumption, making it an attractive option for future chip designs. However, the cost-effectiveness and scalability of producing graphene-based chips still need to be addressed.
