TSMC Reveals 6 nm Course of Expertise: 7 nm with Increased Transistor Density

TSMC unveiled its new 6nm manufacturing expertise (CLN6FF, N6) this week, which is able to ship considerably greater transistor density in comparison with the corporate's 7 nm (CLN7FF, N7) manufacturing course of. As an evolution of TSMC's 7nm node, N6 will proceed to make use of the identical design guidelines, which is able to assist corporations get began within the new course of. The expertise might be used from the primary quarter of 2020 for the danger manufacturing of chips.

TSMC states that its N6 manufacturing expertise gives 18% extra logic density in comparison with the corporate's N7 course of (1st era 7nm, DUV solely), however offers the identical efficiency and energy consumption. In keeping with TSMC N6 & # 39; makes use of N6 & # 39; nevertheless, new alternatives for excessive ultraviolet lithography (EUVL) & nbsp; obtained with N7 + don’t point out precisely how EUV makes use of it for that specific expertise. In the meantime, N6 makes use of the identical design guidelines as N7 and permits chips builders to reuse the identical design ecosystem (eg, instruments, and many others.), which might scale back improvement prices. In essence, N6 permits the die sizes of designs developed utilizing the N7 design guidelines to be decreased by about 15%, whereas the identified IP is used for added price financial savings.

TSMC expects N6 for use in quite a lot of functions, together with cell SoCs, GPUs, excessive efficiency laptop chips, networks, 5G infrastructures, and different merchandise. It stays to be seen if the chip designers will use N6 expertise given the tiny enhancements over N7 when it comes to efficiency, efficiency and space (PPA). Firms with advanced N7-based chips might want to put instantly on N7 + and even 5nm (CLN5FF, N5) for his or her subsequent era.

TSMC will start manufacturing chips with its N6 manufacturing expertise within the first quarter of 2020. Contemplating that it sometimes takes a few 12 months for a corporation to begin large-scale manufacturing (HVM) after the beginning of danger manufacturing N6 for mass-produced merchandise from 2021.
