Nov 26, 2019 · Samsung’s 14nm Process is one of the most widely used fabrication nodes that is used for Nvidia’s GeForce 10 Series, and many Qualcomm & Exynos chips. It has multiple variants, the 14nm LPE (Low Power Early) and 14nm LPP (Low Power Performance). The Transistor density of this process is 32.5 MTr/mm².
Sep 23, 2020 · AleksandarK. Sep 23rd, 2020 01:15 Discuss (49 Comments) Currently, Intel's best silicon manufacturing process available to desktop users is their 14 nm node, specifically the 14 nm+++ variant, which features several enhancements so it can achieve a higher frequencies and allow for faster gate switching. Compare that to AMD's best, a Ryzen 3000 series processor based on Zen 2 architecture, which is built on TSMC's 7 nm node, and you would think AMD is in clear advantage there.

Feb 20, 2018 · Since 22-nm technology node, FinFET has been utilized for several process nodes [ 15, 16, 17 ]. It is firstly introduced by Intel in 22-nm node and widely adopted by different companies in 16- or 14-nm process node. The process integration scheme of FinFET is compatible with that of the planar transistor.
The 14nm and 16nm processes cover a range of technologies and are designed to succeed the 20nm generation. Most are intended to support finFET or trigate transistor structures, although STMicroelectronics is working on an FD-SOI process that conforms to foundry-class 14nm/16nm design rules. The processes being prepared by the major pure-play foundries deploy a new generation of finFETs on a routing infrastructure based on that employed by the previous, conventional CMOS 20nm nodes.
Generally, the length of the transistor is 14nm, the space electrons move from source to drain, the foundation of a transistor. But now a days, it may refer to metal line because there are more than half dozen and current need to flow from top VIA to bottom contact to Source or Drain or Gate.

- Impact of 16/14nm on The Back End Flow
The features in nodes below 20nm are so small that it’s no longer possible to mitigate the effects of diffraction. This is caused by the relatively large light wavelengths (193nm) used during the lithography steps. For this reason it’s necessary to adopt a double patterning masking technique. This allows for the required increase in accuracy necessary to produce the small features, whilst retaining the same lithography techniques used in larger nodes (> 30nm). Advanced lithography techniques,...
Double patterning impacts every part of the IC design phase, from standard cell development to placement, routing, extraction, and physical verification, and there are certain requirements that the designer should know: 1. Cell and library generation must ensure that cells and IP blocks are compliant with double patterning design rules. 2. Placement must avoid potential color conflicts and minimize the area impact of double patterning, while meeting timing, power and routability requirements....
Circuit performance is more dominated by interconnect Rs and Cs Significant crosstalk impact on circuit performance 1. Layer stacks become very heterogeneous 2. RC varies as much as 50x between layers, 3. Significant timing variation due to layer assignment 4. Interconnect optimization is becoming the center-stage of physical design
The move to FinFET brings new challenges to the extraction tools, as the transistors have a variety of 3D fin shapes, that create 3D capacitance. Double patterning has a variation which needs to be taken into account by the extraction tools. You can find out more information from Synopsys and in the semiwiki forum.
Unlike the move to previous nodes, for example moving from 40nm to 28nm, moving to 16nm isn’t only a matter of making the transistor smaller. The move forces us to use both 1. a complex way of creating masks 2. and a different structure of transistor. The impact on the Back End (BE) is that we are using more sets of tools/features to get the job done, and it takes longer to signoff a design (both tool runtime and engineers’ work time). ______________________________________________________________________ This is a guest post by Sondrel, which is an IC design services consultancy company.
