Tsmc already mass produces the first chips at 7nm
Table of contents:
TSMC wants to continue leading the silicon chip manufacturing industry so its investment is huge, the foundry has already started to mass-produce the first chips with its advanced 7nm CLN7FF process, which will allow it to reach new levels of efficiency and benefits.
TSMC begins mass manufacturing of 7nm CLN7FF chips with DUV technology
This year 2018 will be the year of the arrival of the first silicon manufactured at 7 nm, although do not expect high-performance GPUs or CPUs, because the process must first mature, and nothing better for it than manufacturing processors for mobile devices and chip data. memory, which are much smaller and easier to manufacture.
We recommend reading our post on TSMC works on two nodes at 7nm, one of them for GPUs
TSMC compares its new process at 7nm with the current one at 16nm, casting that the new chips will be 70% smaller with the same number of transistors, in addition to consuming 60% less energy, and allowing frequencies of 30% higher operation. Great improvements that will make possible new devices with greater processing capacity, and with an energy consumption equal to that of the current ones or less.
TSMC's CLN7FF 7nm process technology is based on deep ultraviolet (DUV) lithography with argon fluoride (ArF) excimer lasers, operating at a wavelength of 193nm. As a result, the company will be able to use existing manufacturing tools to make chips at 7nm. Meanwhile, to continue using DUV lithography, the company and its customers must use multipastterning (triple and quadruple patterns), increasing design and production costs, as well as product cycles.
Next year, TSMC intends to introduce its first manufacturing technology based on extreme ultraviolet lithography (EUVL) for selected coatings. The CLN7FF + will be the company's second-generation 7nm manufacturing process, due to the compatibility of design rules and because it will continue to use DUV tools. TSMC expects its CLN7FF + to offer 20% higher transistor density and 10% lower power consumption with the same complexity and frequency as the CLN7FF. In addition, TSMC's EUV-based 7nm technology could also offer higher performance and tighter current distribution.
