The Everything New Syndrome
By Ed Sperling - 12 Oct, 2021 - Comments: 0

Technology is all about the latest features, the fastest processing, with the lowest power. While that sounds great in marketing pitch, any or all of those factors don't necessarily equate to a better product or long-term user satisfaction. There's a reason semiconductor companies are conservative by nature. They want to know that when they spend tens or hundreds of millions of dollars on a ... » read more

Specialty Technologies Bring New Functionality
By David Haynes - 19 Aug, 2021 - Comments: 0

As a materials engineer, I am very proud of the fact that key advances in human civilization have been driven by materials innovation. The stone age, bronze age, and iron age were all essential steps in setting the human race on the path that we are on today. Innovations are not without their downsides, but they have enabled progress in agriculture, medicine, transportation, communication, a... » read more

Using Less Helium In Semiconductor Manufacturing
By Terry Powell - 22 Jul, 2021 - Comments: 0

Helium gas is increasingly in short supply. While consumers may be most familiar with it for use in filling balloons, it is used much more heavily in a variety of industrial processes – including semiconductor fabrication. As a result of supply concerns, many companies, including Lam, are looking for ways to reduce their helium usage. The making of a semiconductor chip involv... » read more

Expanded Material Metrology For Refined Etch Selectivities
By Anoop Somanchi - 08 Jun, 2021 - Comments: 0

Trends in advanced device fabrication require combined lithography-etching multi-patterning sequences and self-aligned multi-patterning to form devices’ finest features at subwavelength dimensions. As EUV lithography (13.5 nm) progresses to larger numerical apertures and new thin resists, new multipatterning sequences must be developed with mutually compatible resists and proximal layers t... » read more

Robust Growth And Strong Outlook For Semiconductor Materials
By Inna Skvortsova - 20 May, 2021 - Comments: 0

2020 was a year that made a mark in the history of mankind as well as the semiconductor industry. It was a year of business and personal disruptions caused by COVID-19, supply chain interruptions, and exceptional agility of industries coping with the new normal imposed by the pandemic. Nevertheless, it was a year of extraordinary growth for the semiconductor industry, including semiconductor ma... » read more

Power Converter Chip Research Booms
By Katherine Derbyshire - 18 Feb, 2021 - Comments: 0

Power electronics are booming, fueled by demand ranging from induction chargers for wearable and portable electronics, to charging stations for electric vehicles. An estimated 80% of all U.S. electricity will pass through some form of power converter by 2030, said Yogesh Ramadass, director of power management at Texas Instruments' Kilby Labs. Transportation applications, in particular, deman... » read more

More Data, More Memory-Scaling Problems
By Bryon Moyer - 14 Jan, 2021 - Comments: 0

Memories of all types are facing pressures as demands grow for greater capacity, lower cost, faster speeds, and lower power to handle the onslaught of new data being generated daily. Whether it's well-established memory types or novel approaches, continued work is required to keep scaling moving forward as our need for memory grows at an accelerating pace. “Data is the new economy of this ... » read more

Si Hardmask (Si-HM), EUV And Zero Defects
By Hao Lee - 26 Oct, 2020 - Comments: 0

The multilayer system used in lithography consists of a planarizing carbon layer beneath a hardmask etch-transferring layer and capped with a standard photoresist coating. In the past, Brewer Science has discussed in-depth how the multilayer system helped to extend ArF (193 nm) immersion lithography to be able to print and transfer ever-shrinking features, ensuring enough process window especia... » read more

Next Challenge: Parts Per Quadrillion
By Ed Sperling - 29 Jul, 2020 - Comments: 0

Requirements for purity of the materials used in semiconductor manufacturing are being pushed to unprecedented — and increasingly unprovable — levels as demand for reliability in chips over increasingly longer lifetimes continues to rise. And while this may seem like a remote problem for many parts of the supply chain, it can affect everything from availability of materials needed to make t... » read more
