High lifecycles for batteries with doughnut-shaped lithium sulphide

A “high performing”, doughnut-shaped active material structure inside a lithium-sulphur battery has been developed by the Korea Advanced Institute of Science and Technology (KAIST).This lithium-sulphur (Li-S) battery has a higher energy density and lower production cost than a lithium-ion battery (LIB), according to KAIST. Therefore, it can be used in electric vehicles (EVs) that need a longer battery life.Unfortunately, Li-S batteries are still incapable of providing a longer lifecycle due to the poor reversibility of the lithium metal cathode. To combat this problem, the researchers used lithium sulphide (Li₂S) cathodes and combined them with graphite anodes to enhance energy density and lifecycles for the batteries.Li₂S is expensive and as such there has not been an electrode architecture and electrolyte design that enables a longer lifecycle between the graphite anodes and lithium sulphide cathodes – until now.The team produced its Li₂S cathode active material from low-cost Li₂S developed from raw materials. They have also developed a Li₂S ion battery with a graphite anode and Li₂S cathode using a high concentration salt electrolyte.The team say they achieved 30% higher energy density than that of conventional LIBs and secured a lifecycle of more than 600 cycles.

China’s semiconductor fab capacity to reach 20% worldwide share in 2020

The China IC Ecosystem Report, a comprehensive report for the IC manufacturing supply chain, reveals that front-end fab capacity in China will grow to account for 16 percent of the world’s semiconductor fab capacity this year, a share that will increase to 20 percent by the end of 2020. With the rapid growth, China will top the rest of the world in fab investment in 2020 with more than $20 billion in spending, driven by memory and foundry projects funded by both multinational and domestic companies, according to the new report released today by SEMI.The report also shows that IC Design remained the largest semiconductor sector in China for the second year in a row with $31.9 billion in revenue in 2017, widening its lead over the long-dominant IC Packaging and Test sector. The ascent of China’s IC Design sector comes as the region’s equipment market is expected to claim the top spot in 2020 for the first time on the strength of the continuing development of its domestic manufacturing capability. China’s maturing domestic fab sector is also benefiting domestic equipment and materials suppliers. Both groups continue to see gains in their product offerings and capabilities, particularly in silicon wafer production. The China IC Ecosystem Report is produced by SEMI, the global industry association and provider of independent electronics market research.The more than RMB140 billion (US$21.5 billion) accumulated by the National IC Fund, a critical component of the 2014 National Guideline to address China’s semiconductor trade deficit, has spurred rapid gains throughout the region’s IC supply chain. Semiconductors are China’s largest import by revenue. Phase 2 of funding aims to raise another RMB150-200 billion ($23.0-$30.0 billion).Encouraged by the National Guideline and favorable policies, skilled overseas talent is returning to China, triggering an explosion of domestic IC Design start-ups that are benefiting from access to investment and favorable policies, the report shows.Other highlights from The China IC Ecosystem Report include:Currently 25 new fab construction projects are underway or planned in China. 17 – 300 mm fabs are being tracked as part of this investment and expansion activity. Foundry, DRAM and 3D NAND are the leading segments for fab investment and new capacity in China.China’s IC Packaging and Test industry is also moving up the value chain by enhancing its technology offerings through mergers and acquisitions and building advanced capabilities to entice international integrated device manufacturers.China’s IC materials market, currently dominated by Packaging materials, became the second largest regional market for materials in 2016, a position it solidified in 2017. China’s materials market is expected to grow at a 10 percent CAGR from 2015 to 2019, driven primarily by the region’s new fab capacity ramp in the coming years. Fab capacity will expand at a 14 percent CAGR during that period.

Worldwide semiconductor revenue hit record $120.8B in Q2 2018

Global semiconductor industry revenue grew 4.4 percent, quarter over quarter, in the second quarter of 2018, reaching a record $120.8 billion. Semiconductor growth occurred in all application markets and world regions, according to IHS Markit (Nasdaq: INFO).“The explosive growth in enterprise and storage drove the market to new heights in the second quarter,” said Ron Ellwanger, senior analyst and component landscape tool manager, IHS Markit. “This growth contributed to record application revenue in data processing and wired communication markets as well as in the microcomponent and memory categories.”Due to the ongoing growth in the enterprise and storage markets, sequential microcomponent sales grew 6.5 percent in the second quarter, while memory semiconductor revenue increased 6.4 percent. “Broadcom Limited experienced exceptional growth in its wired communication division, due to increased cloud and data-center demand,” Ellwanger said.Memory component revenue continued to rise in the second quarter, compared to the previous quarter, reaching $42.0 billion dollars. “This is the ninth consecutive quarter of rising revenue from memory components, and growth in the second quarter of 2018 was driven by higher density in enterprise and storage,” Ellwanger said. “This latest uptick comes at a time of softening prices for NAND flash memory. However, more attractive pricing for NAND memory is pushing SSD demand and revenue higher.”Semiconductor market shareSamsung Electronics continued to lead the overall semiconductor industry in the second quarter with 15.9 percent of the market, followed by Intel at 13.9 percent and SK Hynix at 7.9 percent. Quarter-over-quarter market shares were relatively flat, with no change in the top-three ranking.

Global GDP Impact on Worldwide IC Market Growth Forecast to Rise

In its recently released Mid-Year Update to The McClean Report 2018, IC Insights forecasts that the 2018-2022 global GDP and IC market correlation coefficient will reach 0.95, up from 0.88 in the 2010-2017 timeperiod. IC Insights depicts the increasingly close correlation between worldwide GDP growth and IC market growth through 2017, as well as its forecast through 2022, in Figure 1.As shown, over the 2010-2017 timeframe, the correlation coefficient between worldwide GDP growth and IC market growth was 0.88, a strong figure given that a perfect correlation is 1.0. In the three decades previous to this timeperiod, the correlation coefficient ranged from a relatively weak 0.63 in the early 2000s to a negative correlation (i.e., essentially no correlation) of -0.10 in the 1990s.IC Insights believes that the increasing number of mergers and acquisitions, leading to fewer major IC manufacturers and suppliers, is one of major changes in the supply base that illustrate the maturing of the industry that is helping foster a closer correlation between worldwide GDP growth and IC market growth. Other factors include the strong movement to the fab-lite business model and a declining capex as a percent of sales ratio, all trends that are indicative of dramatic changes to the semiconductor industry that are likely to lead to less volatile market cycles over the long term.In 2017, IC industry growth was greatly influenced by the “Capacity/Capital Spending Cycle Model” as the DRAM and NAND flash markets surged and served to drive total IC industry growth of 25%. It would initially appear that the strong correlation coefficient between worldwide GDP growth and total IC market growth that had been evident from 2010 through 2016 had disappeared in 2017. However, IC Insights does not believe that is the case.When excluding the DRAM and NAND flash segments from the IC market in 2017, the remainder of the IC market displayed an 11% increase, which closely correlates to what would be expected given a worldwide GDP increase from 2.4% in 2016 to 3.1% in 2017. Moreover, the three-point decline in the total IC market growth rate forecast for 2018, when excluding DRAM and NAND flash (from 11% in 2017 to 8% in 2018), is expected to mirror the slight decline expected for worldwide GDP growth this year as compared to last year. Thus, excluding the amazing surge for the DRAM and NAND flash markets in 2017 and 2018, IC Insights believes that the trend toward an increasingly close correlation between total IC market growth and worldwide GDP growth is still largely intact.Figure 1

STMicro Sees Strong Demand for Silicon Carbide

As STMicroelectronics reported its first quarterly results since President and CEO Jean-Marc Chery took the helm, the company was bullish about its automotive market pipeline, and especially for its silicon carbide (SiC) products from which it expects revenues of $100 million in 2018.“We have more than 25 automotive projects in discussion, and 85% of these are in SiC," Chery said. "We are preparing our capital expenditure next quarter to support this, as SiC will be an important game changer for the industry.”Asked by analysts about his confidence level in growth in the automotive and industrial sector for ST, he said, “We don’t see any weak signals, we are really confident as demand is really strong.”Chery said that the second quarter saw design wins for its third generation SiC MOSFETS and SiC diodes for car electrification in Asia and Europe, plus a custom galvanic isolation gate driver for an electric vehicle, a chipset for braking applications in Europe, ICs for engine management for Japanese and Korean customers, and an SP58 32-bit microcontroller win for a body control module for a European tier one supplying a U.S. car maker.He also said that in the personal electronics sector, while sales to its lead customer for smartphones (Apple) will see growth as it launches its new models in September, a key highlight was a design win for its STM32F7 in a high-end 4K TV at a key Japanese OEM. “This was previously a difficult market for us to penetrate,” Chery said.Second quarter net revenues and gross margin were above the mid-point of the company’s outlook. ST reported second quarter net revenues of $2.27 billion, gross margin of 40.2%, operating margin of 12.7%, and net income of $261 million or $0.29 diluted earnings per share.Asked about the potential impact of the trade war between the U.S. and China, Chery said, “At this moment, the direct impact is negligible. But we are monitoring the situation. If the trade war escalates, we are more concerned about the macro level impact on the industry, but we have nothing more to add at this stage.”Responding to questions about ST’s M&A strategy, he said that the company is continuing it strategy of organic growth for 2018, supported my small acquisitions to support areas like its STM32 products, such as its recent acquisition of Draupner Graphics. He added that the company would update the market on its M&A strategy towards the end of the year, though it may potentially make small IP company acquisitions to improve its portfolio.

Cloud Service Providers to Put More Emphasis on Edge Computing

Cloud computing platforms have fueled the digital transformation of enterprises in recent years. Public cloud has been playing a key role during the process. While applications of IoT and AI grow increasingly popular, the ecosystem of cloud services and the integration of cloud and edge have emerged as weak points of the market, says TrendForce. Cloud service providers have started to put more emphasis on the edge computing market, which has a CAGR of more than 30% from 2018 to 2022.TrendForce analyst Jimmy Liu points out that the digital transformation has become a must for many enterprises, who have realized the challenges brought by massive data to their current information system architectures. Cloud services like storage, data transmission and computing are on the rise, changing the mindsets of enterprises. Major cloud service providers have made eye-catching achievements in recent years, such as Amazon, Microsoft, Google, IBM, and Alibaba Cloud.However, with increasing growth momentum, the competition among cloud service providers has also become fierce. Before incorporating cloud systems into daily business operations, enterprises are bound to consider the stability, cost-effectiveness, scalability, and sustainability of cloud services, urging service providers to make the functions more integrated and prices more competitive.In addition, the rise of the Internet of Things has brought dynamic development needs. Users not only upload their systems to the cloud, but also use the cloud platforms for development and testing of IoT applications, further optimizing development costs and shortening the time for product development.Faced with existing price competition and the emerging diverse needs, cloud service providers started to extend their existing businesses and expand towards IoT platforms and edge computing. Liu notes that, most cloud service providers have established their own IoT platforms and edge computing software, such as AWS IoT Core and AWS Greengrass of Amazon, Azure IoT Solutions and Azure IoT Edge of Microsoft, etc. Based on cloud ecosystems, complete architecture and functions, as well as corresponding development tools for users, the cloud service providers have been shifting to the edge, trying to deliver more comprehensive cloud-to-end solutions on the advantages of the cloud.Cloud-to-end solutions also assist in data analysis by service providers, who used to collect existing data from applications passively. Together with a large amount of messy data, the analysis was time- and effort-consuming. However, as the cloud-to-edge development tools and ecosystems are built, they can cooperate with edge device makers more actively and have better control of these devices closer to the sources of data such as sensors, end devices, and gateways.In addition, the enhancement of edge devices will also enable cloud service providers to deploy artificial intelligence, machine learning and other technologies to the edge, and to upgrade vertical fields through various algorithms. The integration of cloud computing, edge computing and professional domain knowledge will also drive the loop of automation, autonomous training, and self-optimization. In this way, cloud service providers and edge device makers will jointly develop new forms of operation in the future to realize the digital transformation.
