New Power Concerns At 10/7nm


As chip sizes and complexity continues to grow exponentially at 7nm and below, managing power is becoming much more difficult. There are a number of factors that come into play at advanced nodes, including more and different types of processors, more chip-package decisions, and more susceptibility to noise of all sorts due to thinner insulation layers and wires. The result is that engineers ... » read more

Reliability Of eWLB For Automotive Radar Applications


With shrinking of chip sizes, Wafer Level Chip Scale Packaging (WLCSP) becomes an attractive and holistic packaging solutions with various advantages in comparison to conventional packages, such as Ball Grid Array (BGA) with flipchip or wirebonding. With the advancement of various fan-out (FO) WLPs, it has been proven to be a more optimal, low cost, integrated and reliable solution compared to ... » read more

Addressing Thermal Reliability In Next-Gen FinFET Designs


The next generation of chips on the 10/7nm finFET processes will be able to cram more devices into same area while also boosting performance, but there's a price to pay for that. The 3D fin structures trap heat, so the the temperature rises on the device and there is no way to dissipate that heat. This combination of higher current density, higher performance and higher temperature has a det... » read more

Tech Talk: 7nm Thermal Effects


ANSYS' Karthik Srinivasan talks about the effect of heat on reliability at advanced process nodes, including self-heating, circuit aging, and how that will affect automotive electronics. https://youtu.be/SS6iAXp0Kn8   Related Tech Talk: 7nm Power Dealing with thermal effects, electromigration and other issues at the most advanced nodes. » read more

How To Make Autonomous Vehicles Reliable


The number of unknowns in automotive chips, subsystems and entire vehicles is growing as higher levels of driver assistance are deployed, sparking new concerns and approaches about how to improve reliability of these systems. Advanced Driver Assistance Systems (ADAS) will need to detect objects, animals and people, and they will be used for parking assistance, night vision and collision avoi... » read more

How Reliable Are FinFETs?


Stringent safety requirements in the automotive and industrial sectors are forcing chipmakers to re-examine a number of factors that can impact reliability over the lifespan of a device. Many of these concerns are not new. Electrical overstress (EOS), electrostatic discharge (ESD) and [getkc id="160" kc_name="electromigration"] (EM) are well understood, and have been addressed by EDA tools f... » read more

The Rising Value Of Data


The volume of data being generated by a spectrum of devices continues to skyrocket. Now the question is what can be done with that data. By Cisco's estimates, traffic on the Internet will be 3.3 zetabytes per year by 2021, up from 1.2 zetabytes in 2016. And if that isn't enough, the flow of data isn't consistent. Traffic on the busiest 60-minute period in a day increased 51% in 2016, compare... » read more

Who’s Responsible For Transistor Aging Models?


While there are a number of ways to go about reliability and transistor aging analysis, it is all in large part dependent on fabs and foundries to provide the aging models. The situation is also not entirely clear in the semiconductor ecosystem because the classic over-the-wall mentality between design and manufacturing still exists. And unfortunately this wall is bi-directional. Not onl... » read more

Transistor Aging Intensifies At 10/7nm And Below


Transistor aging and reliability are becoming much more troublesome for design teams at 10nm and below. Concepts like ‘infant mortality’ and 'bathtub curves' are not new to semiconductor design, but they largely dropped out of sight as methodologies and EDA tools improved. To get past infant mortality, a burn-in process would be done, particularly for memories. And for reliability, which... » read more

Chip Test Shifts Left


“Shift left” is a term traditionally applied to software testing, meaning to take action earlier in the V-shaped time line of a project. It has recently been touted in electronic design automation and IC design, verification, and test. “Test early and test often” is the classic maxim of software testing. What if that concept could also be implemented in semiconductor testing, to redu... » read more
