QUAC-TRNG: High-Throughput True Random Number Generation Using Quadruple Row Activation in Commodity DRAM Chips
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract "True random number generators (TRNG) sample random physical processes to create large amounts of random numbers for various use cases, including security-critical cryptographic primitives, scientific simulations, machine learning applications, and even recreational entertainment. Unfortunately, not every computing system is equipped with dedicated TRNG hardware, limiting the applicat... » read more

HARP: Practically and Effectively Identifying Uncorrectable Errors in Memory Chips That Use On-Die Error-Correcting Codes
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract: "State-of-the-art techniques for addressing scaling-related main memory errors identify and repair bits that are at risk of error from within the memory controller. Unfortunately, modern main memory chips internally use on-die error correcting codes (on-die ECC) that obfuscate the memory controller's view of errors, complicating the process of identifying at-risk bits (i.e., error pr... » read more

End In Sight For Chip Shortages?
By Mark LaPedus - 18 Nov, 2021 - Comments: 2

The current wave of semiconductor and IC packaging shortages is expected to extend well into 2022, but there are also signs that supply may finally catch up with demand. The same is true for manufacturing capacity, materials and equipment in both the semiconductor and packaging sectors. Nonetheless, after a period of shortages in all segments, the current school of thought is that chip suppl... » read more

The Race To Make Better Qubits
By Katherine Derbyshire - 18 Nov, 2021 - Comments: 0

One of the big challenges in quantum computing is getting qubits to last long enough to do something useful with them. After decades of research, there now appears to be tangible progress. The challenge with any new semiconductor technology is to improve performance by one or more orders of magnitude without discarding a half-century of progress in other areas. Qubits based on silicon quantu... » read more

Outlook: DRAM, NAND, Next-Gen Memory
By Mark LaPedus - 18 Nov, 2021 - Comments: 0

Jim Handy, director at Objective Analysis, sat down with Semiconductor Engineering to talk about the 3D NAND, DRAM and next-generation memory markets. What follows are excerpts of that discussion. SE: How would you characterize the NAND market thus far in 2021? Handy: All chips are seeing unusual strength in 2021, but NAND flash and DRAM are doing what they usually do by exhibiting more e... » read more

The New Technology Solutions For Advanced SiP Devices
By YongJai Seo - 18 Nov, 2021 - Comments: 0

For many years, System-in-Package (SiP) technology has been a focus for semiconductor packaging to address the ongoing market trend of system integration and size reduction. Today’s increased complexity and higher package density for SiP devices has driven the development of new packaging technologies. In response, compartmental shield technology makes it possible to put several functions int... » read more

Using Process Modeling To Enhance Device Uniformity During Self-Aligned Quadruple Patterning
By Timothy Yang - 18 Nov, 2021 - Comments: 0

Despite the growing interest in EUV lithography, self-aligned quadruple patterning (SAQP) still holds many technical advantages in pattern consistency, simplicity, and cost. This is particularly true for very simple and periodic patterns, such as line & space patterns or hole arrays. The biggest challenge of SAQP is the inherently asymmetric mask shape. This asymmetry can create structural ... » read more

Failure Prediction Is Vital for Packaging Technology
By Sam Sadri - 18 Nov, 2021 - Comments: 0

A while back, I wrote a post on what I call the “10 Commandments of Packaging” – my list of the key things to bear in mind with respect to developing new packaging solutions. Today, packaging engineers must contend with more variables than ever, from new substrate materials to more types of packages with a greater range of complexity. With that complexity comes new challenges, and I felt ... » read more

Semiconductor Photomask Revenues Predicted To Increase In 2021
By Jan Willis - 18 Nov, 2021 - Comments: 0

A majority (72%) of industry luminaries surveyed in July predict an increase in photomask revenues for 2021, as shown in figure 1. SEMI also predicts revenues to increase around 9% from $4.4B in 2020 to $4.8B in 2021. In a 12-minute video, a panel of experts share their perspectives on what’s behind the growth trend, how the pandemic has impacted the photomask industry, and how it compares to... » read more

Workplace Safety Lessons From The Deepwater Horizon Oil Spill
By McKenzie Turner - 18 Nov, 2021 - Comments: 0

The Deepwater Horizon oil spill on April 20th, 2010, was the largest marine oil spill in history, marking a significant change in the oil industry and safety standards thereafter. What data do we have on the Deepwater Horizon oil spill? BP leased the oil rig, however, it was owned and operated by an offshore company called Transocean. The drilling reached a depth of nearly 1 mile, at 5,000 ... » read more
