The Past Predicting The Future
By Brian Bailey - 22 Dec, 2021 - Comments: 0

It is often said that you cannot predict the future by looking at the past, but that isn't always correct. There are many clues provided by digging into change. Those changes are a prelude to what may happen in the future. One way we can do that here at Semiconductor Engineering is by looking at changes in reading habits. What types of articles are attracting the most attention? This is a sure ... » read more

Challenges With Stacking Memory On Logic
By Ed Sperling - 22 Dec, 2021 - Comments: 1

Experts at the Table: Semiconductor Engineering sat down to discuss the changes in design tools and methodologies needed for 3D-ICs, with Sooyong Kim, director and product specialist for 3D-IC at Ansys; Kenneth Larsen, product marketing director at Synopsys; Tony Mastroianni, advanced packaging solutions director at Siemens EDA; and Vinay Patwardhan, product management group director at Cadence... » read more

The Third Generation Of FPGA Prototyping
By Robert Parris - 22 Dec, 2021 - Comments: 0

Bench setups with physical prototypes lie at the very heart of electrical and electronic engineering. With all due respect to the many powerful forms of modeling and simulation, at some point the engineering team wants to work with hardware. When a system is built entirely from existing components, it is possible to build a prototype of the product as soon as it has been designed. When the desi... » read more

Sustainability, Ecosystems, And Consumer Requirements In 2022
By Frank Schirrmeister - 22 Dec, 2021 - Comments: 0

Last December, my 2021 outlook focused on "industry transformations" across different verticals. I had referenced a lot of the ongoing transformations in hyperscale computing, aerospace/defense, automotive, and healthcare. 2021 didn't disappoint—most of what I discussed further accelerated pace. For instance, pretty much no booth felt complete at the annual Army AUSA event if they were not... » read more

EDA In The Cloud Is Driving Semiconductor Innovation
By Nebabie Kebebew - 22 Dec, 2021 - Comments: 0

In the past decade, the move towards cloud computing occurred primarily in sectors like finance, retail, and healthcare, with the emergence of leading public cloud vendors such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and others accelerating the trend. However, the chip design industry has been slower to adopt cloud computing. In the current highly competitive en... » read more

Growth And Enthusiasm At The RISC-V Summit 2021
By Rupert Baines - 22 Dec, 2021 - Comments: 0

We weren’t sure what to expect from our first major attendance at a #RISCVSummit. Although we were a founding member of RISC-V – as we’ve been saying quite a lot recently – we have been hiding our light under a bushel. We’ve certainly been busy though – enabling over 2 billion RISC-V cores with our RISC-V processor IP and Studio tools while helping customers use architecture lice... » read more

Light-Emitting V-Pits: An Alternative Approach toward Luminescent Indium-Rich InGaN Quantum Dots
By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "Realization of fully solid-state white light emitting devices requires high efficiency blue, green, and red emitters. However, challenges remain in boosting the low quantum efficiency of long wavelength group-III-nitride light emitters through conventional quantum well growth. Here, we demonstrate a new direct metal–organic chemical vapor deposition approach to grow In-rich InGa... » read more

The Role of InGaN Quantum Barriers in Improving the Performance of GaN-based Laser Diodes
By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "In this work, different aspects which have influences on device performance of blue laser diodes (LDs) when using InGaN instead of GaN as quantum barrier (QB) layers are investigated theoretically and experimentally. In the modeling calculation, it is found that the threshold current of LDs with InGaN QB layers is reduced obviously, but the slope efficiency is not largely improved... » read more

Crystal Phase Control during Epitaxial Hybridization of III-V Semiconductors with Silicon
By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "The formation and propagation of anti-phase boundaries (APBs) in the epitaxial growth of III-V semiconductors on Silicon is still the subject of great debate, despite the impressive number of studies focusing on this topic in the last past decades. The control of the layer phase is of major importance for the future realization of photonic integrated circuits that include efficien... » read more

Weight Adjustable Photonic Synapse by Nonlinear Gain in a Vertical Cavity Semiconductor Optical Amplifier
By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "In this paper, we report a high-speed and tunable photonic synaptic element based on a vertical cavity semiconductor optical amplifier (VCSOA) operating with short (150 ps-long) and low-energy (μW peak power) light pulses. By exploiting nonlinear gain properties of VCSOAs when subject to external optical injection, our system permits full weight tunability of sub-ns input light p... » read more
