X-bit Labs published some details regarding GlobalFoundries' upcoming 20nm process, which will be developed alongside the 22nm process.
Globalfoundries, the contract maker of semiconductors controlled by Advanced Technology Investment Company and Advanced Micro Devices, said that it would develop 20nm process technology, along with 22nm fabrication process. Besides, the company indicated that the so-called half-node process technologies would continue to exist, despite of the recent trends.
Recently Taiwan Semiconductor Manufacturing Company announced plans to skip 22nm process technology and to move straight to 20nm instead. In addition, both leading contract makers of semiconductors – Globalfoundries and TSMC – decided to skip 32nm bulk process technologies. While Globalfoundries has done this because of certain business reasons, TSMC had too many problems with 40nm to use the same materials and design with 32nm. Previously, almost everyone in the foundry industry have introduced so-called half-node processes, e.g. 55nm, which was a derivative of the 65nm. Although these practices show that full-node processes are losing importance, Globalfoundries claims that going forward both half-node and full-node process technologies will co-exist.
