Reducing Transistor Capacitance At The 5nm Node Using A Source/Drain Contact Recess

By Pradeep Nanja - 19 Sep, 2024 - Comments: 0

In logic devices such as FinFETs (field-effect transistors), metal gate parasitic capacitance can negatively impact electrical performance. One potential way to reduce this parasitic capacitance is to add a source/drain contact (CT) recess step when building the source/drain metal structure. However, this additional structure can potentially increase the source/drain to via resistance. Using... » read more

What Will That Chip Cost?

By Brian Bailey - 30 Oct, 2023 - Comments: 1

In the past, analysts, consultants, and many other experts attempted to estimate the cost of a new chip implemented in the latest process technology. They concluded that by the 3nm node, only a few companies would be able to afford them — and by the time they got into the angstrom range, probably nobody would. Much has changed over the past few process nodes. Increasing numbers of startups... » read more

Designing For In-Circuit Monitors

By Ann Mutschler - 27 Apr, 2023 - Comments: 0

In every application space the semiconductor ecosystem touches, in-circuit monitors and sensors are playing an increasing role in silicon lifecycle management and concepts around reliability and resiliency — both during design as well as in the field. The combination of true system-level design, in/on-chip monitors, and improved data analysis are expected to drastically improve reliability... » read more

Challenges Grow For CD-SEMs At 5nm And Beyond

By Gregory Haley - 11 Apr, 2023 - Comments: 1

CD-SEM, the workhorse metrology tool used by fabs for process control, is facing big challenges at 5nm and below. Traditionally, CD-SEM imaging has relied on a limited number of image frames for averaging, which is necessary both to maintain throughput speeds and to minimize sample damage from the electron beam itself. As dimensions get smaller, these limitations result in higher levels of n... » read more

Physically Aware NoCs

By Ed Sperling - 06 Mar, 2023 - Comments: 0

More functions, greater security risks, and increasingly complicated integration of IP and various components below 7nm is increasing the time and effort it takes to get a functioning chip out the door. In many of these devices, the network on chip is the glue between various components, but it can take up to 10% to 12% of the total area of the SoC. Andy Nightingale, vice president of product m... » read more

Screening For Silent Data Errors

By Anne Meixner - 10 Jan, 2023 - Comments: 0

Engineers are beginning to understand the causes of silent data errors (SDEs) and the data center failures they cause, both of which can be reduced by increasing test coverage and boosting inspection on critical layers. Silent data errors are so named because if engineers don’t look for them, then they don’t know they exist. Unlike other kinds of faulty behaviors, these errors also can c... » read more
