Big Changes In Materials And Processes For IC Manufacturing
By Ed Sperling And Laura Peters - 21 Apr, 2022 - Comments: 3

Rama Puligadda, CTO at Brewer Science, sat down with Semiconductor Engineering to talk about a broad set of changes in semiconductor manufacturing, packaging, and materials, and how that will affect reliability, processes, and equipment across the supply chain. SE: What role do sacrificial materials play in semiconductor manufacturing, and how is that changing at new process nodes? Puliga... » read more

Slowdown, But No Correction
By Ed Sperling - 06 Apr, 2022 - Comments: 1

The market for chips will continue to grow over the next few years, but not as quickly as over the past couple years when the work-at-home market drove up demand for everything from laptops and TVs to home video equipment. Economists painted a mixed picture for the semiconductor industry at this week's SEMI Industry Strategy Symposium, projecting continue growth in all major markets, but tem... » read more

Sustainability In Creating Next-Gen Materials
By Jessica Albright - 20 Jan, 2022 - Comments: 0

In recent years, sustainable manufacturing has become increasingly vital in the materials industry with growing concerns about the impact of manufacturing on the environment. Minimizing the intrinsic risks associated with any manufacturing operation while maximizing the quality and opportunities that arise with improved products is and should be the goal of almost every manufacturer today. At... » read more

Reconstruction of Bloch wavefunctions of holes in a semiconductor
By Technical Paper Link - 07 Dec, 2021 - Comments: 0

Summary "A central goal of condensed-matter physics is to understand how the diverse electronic and optical properties of crystalline materials emerge from the wavelike motion of electrons through periodically arranged atoms. However, more than 90 years after Bloch derived the functional forms of electronic waves in crystals [1] (now known as Bloch wavefunctions), rapid scattering processes ha... » read more

Standards for the Characterization of Endurance in Resistive Switching Devices
By Technical Paper Link - 03 Nov, 2021 - Comments: 0

Abstract "Resistive switching (RS) devices are emerging electronic components that could have applications in multiple types of integrated circuits, including electronic memories, true random number generators, radiofrequency switches, neuromorphic vision sensors, and artificial neural networks. The main factor hindering the massive employment of RS devices in commercial circuits is related to... » read more

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
