Figure 1 below. lists several of the leading advanced logic technologies that companies are presently using. Derivative versions of each process generation between major nodes have become regular occurrences.
The advancement of the IC industry hinges on the ability of IC manufacturers to continue offering more performance and functionality for the money. As mainstream CMOS processes reach their theoretical, practical, and economic limits, lowering the cost of ICs (on a per-function or per-performance basis) is more critical and challenging than ever.
Below is an outline of the report's findings.....
Intel — Its ninth-generation processors unveiled in late 2018 have the code-name “Coffee Lake-S”, Intel says these processors are a new generation of products, but they seem to be more of an enhancement of the eighth-generation products. Details are scarce, but these processors appear to be manufactured on an enhanced version of the 14nm++ process, or what might be considered a 14nm+++ process.
The N7+ process will employ EUV only on critical layers (four layers), while the N5 process will use EUV extensively (up to 14 layers). N7+ is scheduled to enter volume production in the second quarter of 2019.
For five decades, there have been amazing improvements in the productivity and performance of integrated circuit technology. While the industry has surmounted many obstacles put in front of it, it seems the barriers keep getting bigger. Despite this, IC designers and manufacturers are developing solutions that seem more revolutionary than evolutionary to increase chip functionality.
