In order to consolidate its memory hegemony, Samsung Electronics established a blueprint for DRAM development and outlined the progress of the process. The industry estimates that 15 nanometers may be the limit of DRAM process miniaturization, worrying that Samsung was caught up by the Chinese industry.
Korean media etnews reported on the 18th that industry sources said that Samsung began mass production of 18nm DRAM last year and is currently developing 17nm DRAM, which is scheduled to be completed at the end of this year and mass production next year. At the same time, Samsung also set up a 16-nm DRAM development team with the goal of mass production in 2020. According to related sources, the miniaturization is difficult and the production time in 2020 may be postponed.
Samsung switched from a 20-nanometer process (28→25→20) to a 10-nanometer process (18→17), and the speed at which the line-width was reduced significantly slowed. Samsung has not yet set up a R&D team below the 15nm process line. Since this began, current leakage and capacitor interference and conditions will become more apparent and new materials will need to be developed.
According to Jung Eun-seung, a semiconductor lab worker at Samsung's equipment solutions division, in order to continue to reduce the line width, new materials that are different from the current ones must be developed, and the process stability must be increased in order to enter mass production.
Industry figures estimate that 15nm may be the limit of process miniaturization. In the future, Samsung may find it difficult to narrow the gap with its rivals through process miniaturization, and is concerned that Chinese companies are catching up with Samsung and catching up with Samsung.
