The 5nm process technology refers to a semiconductor manufacturing process that allows for the creation of transistors with a size of just 5 nanometers. This smaller size enables more transistors to fit on a single chip, improving performance and energy efficiency. It is a significant advancement over previous technologies, such as 7nm and 10nm processes. This technology is primarily used in the production of microprocessors and graphics processing units (GPUs) for devices like smartphones, computers, and servers. Companies like Apple and Samsung have adopted 5nm technology to enhance the capabilities of their latest chips, leading to faster processing speeds and better battery life.
