The 5G network has been commercially available for four years. Recently, many companies have been talking about the future of the 6G network. The general expectation is that the future of the 6G network will be commercially available by 2030, but Samsung and other companies are planning to commercialize the network as early as 2028 to get a head start.
Compared with 5G network, although there is no clear specification for 6G network, the network speed is 10 to 100 times that of 5G, which can reach 1Tbps or even 10Tbps. At the same time, the delay is lower, and the global sea, land and air interconnection is also required, which greatly improves the coverage rate.
These improvements also put forward higher requirements for chips in the 6G era. Currently, the advanced technology used in 5G chips is 7nm, 5nm,Some models will be upgraded to 4nm and 3nm soon, but it is far from the 6G requirement.
Since 6G is set for 2030, the technology level will be higher in seven or eight years, Pan Zhengang, chief expert of Unigroup Zhanrui, previously said.The 6G era will begin with the 1.5nm GAA process, and will develop after the equivalent of 1nm and 0.7nm GAA.
Currently, Samsung and Taiwan Semiconductor Manufacturing Co., Ltd. have announced a roadmap for mass production of 2nm GAA technology around 2025, 1.4nm technology in 2027, and 1nm and later technologies until at least 2029.
However, these technologies have not yet been implemented by the company, and are mostly developed in the laboratory. Commercial production is still a long way off.
