Seen as a major boost to 5G mobile communications, Samsung announced that its foundry division has developed 8 nanometer (nm) process technology for radio frequency (RF) chips.
This foundry technology provides a single-chip RF solution, especially for 5G communications. The expansion of Samsung’s 8nm RF platform is expected to extend its leadership in the 5G semiconductor market from sub 6GHz to millimeter-wave applications.
Samsung claims that the 8nm process improves power efficiency by 35% and reduces chip area by 35% compared to the 14nm process.
The RF chip converts the digital signal from the modem chip to analog, converts it to usable radio frequencies, and sends it to the modem chip. It consists of a logic circuit area for frequency band change and digital-analog signal conversion, and an analog circuit area for frequency reception and amplification.
8nm RF uses less power
“As 5G millimeter waves grow, Samsung’s 8nm RF is great for customers who demand long battery life and excellent signal quality in compact mobile devices,” said Hyung Jin Lee, master of Samsung Electronics’ foundry technology development team. It will be a solution. “
Samsung states that it has developed a new architecture called RF Extreme FETs (RFeFETs). It is dedicated to 8nm RF and can significantly improve RF characteristics with less power.
He argued that this would reduce the number of transistors and power consumption while reducing the area of the analog circuit.
Samsung launched RF foundry service on the 28nm process in 2015. Then a 14nm based RF was generated. Since 2017, the company has shipped more than 500 million mobile RF chips for premium smartphones.
Samsung hopes that the latest technology will further strengthen its position in the contract chip manufacturing sector.
Samsung is currently the world’s largest manufacturer of computer memory and displays, but wants to be the dominant player in the $ 250 billion foundry and logic chip industry, which is expected to move even bigger thanks to the development of artificial intelligence and the fifth generation. I think. Wireless technology.
