Samsung has finally made it possible to build the much anticipated 7 nanometer chips. The company is using Extreme Ultraviolet (EUV) technology to achieve this breakthrough. The process faced many challenges in the real world and it is finally becoming a reality.
The chips are made by using light to project patterns of circuitry onto silicon wafers. The next generation of chips, however, have features that are smaller than the wavelength of a traditional light. For example, Samsung’s existing 10nm and 14nm chips are exposed to 193nm wavelength light many, many times in a method called multi-patterning. While the new generation chip is where a thin ballpoint is needed.
The solution? Using EUV, which has a wavelength of 13.5nm. But machines are expensive and technological issues have delayed high-volume production. According to Samsung, two major challenges it’s faced have been the power of the light source and the volume of wafers that could be processed every day.
Hopefully, Samsung has figured out a way and it’s getting set to commercialize chips that have a 40 percent smaller surface area compared to the company’s previous 10-nanometer tech, while reducing power consumption by 50 percent or boosting performance by 20 percent.
This innovation clearly gives Samsung, a huge leap ahead of its competitors. Since Samsung supplies a whole range of other companies with its tech, it won’t be long before you’re enjoying exactly that.
