“In 2019, under the new global political and economic trend, the long-term good development trend of the Electronic semiconductor industry seems to add some uncertainty. Although major semiconductor manufacturers have narrowed their “front lines”, deepened their advantageous vertical fields, and expanded their layouts and invested extensively in emerging markets, they have always been inseparable from the topic of exploring innovative technologies and trying to make breakthroughs.
In 2019, under the new global political and economic trend, the long-term good development trend of the electronic semiconductor industry seems to add some uncertainty. Although major semiconductor manufacturers have narrowed their “front lines”, deepened their advantageous vertical fields, and expanded their layouts and invested extensively in emerging markets, they have always been inseparable from the topic of exploring innovative technologies and trying to make breakthroughs. According to the author’s observation, the well-known manufacturer Fujitsu Semiconductor is working with ecological partners to expand its layout in multiple industries. In addition to the secondary innovation of traditional superior technologies, it also continues to launch a variety of emerging application solutions to demonstrate its accumulated technical hard power!
An industry first!A true-pseudo verification scheme based on the spectral characteristics of FRAM debuts
Since its successful mass production 20 years ago, Fujitsu FRAM has shipped more than 3.7 billion units, which are widely used in basic fields such as industrial water and electricity meters and the Internet of Things. In recent years, it has continuously won large orders in the medical, automotive and other industries. Among them, the three “hard core” advantages of almost labelled high read and write durability, high-speed writing and low power consumption have established Fujitsu FRAM’s illustrious reputation. However, in addition to the traditional advantages of continuing the role of “memory”, Fujitsu is trying to bring FRAM to a new product life. This time, it is based on the unique spectral characteristics of FRAM!
“In the process of continuous research on FRAM, Fujitsu found that FRAM has very unique physical spectrum characteristics, and it will generate a period of simulated working noise signal when it is started; and this noise signal is irregular and difficult to be imitated and copied. Using such a principle With the advantages, manufacturers can not only carry out fake certification of products, but also prevent authorized products from being counterfeited and entering the market, thus protecting the rights and interests of both manufacturers and consumers.” Feng Yixin, Director of Product Management Department of Fujitsu Electronic components (Shanghai) Co., Ltd. say.
Most of the common hardware authentication solutions on the market now use encryption algorithms, private keys and other methods to verify the authenticity of the product. For example, in the business model of a printer manufacturer, in addition to selling the main body of the printer, the sale of consumables such as ink cartridges is also an important source of revenue. In order to ensure that consumers buy high-quality products made by the original factory, it is necessary to verify the authenticity when the ink cartridge is connected to the printer. Generally speaking, printer manufacturers use embedded encryption algorithms, and these encryption algorithms are often broken within 1-2 years after their launch, causing counterfeit products to flow into the market. Feng Yixin said: “In response to such customer needs, Fujitsu has developed an LSI chip that uses FRAM operating noise to verify. This is the industry’s first certification scheme with new spectrum characteristics!” Instead of the previous encryption algorithm, this encryption-free algorithm (spectrum )’s true fake authentication solution brings two advantages to customers: one is that there will be no key theft (because there is no key), and security can be achieved at a lower cost; the other is that Fujitsu FRAM can generate Weak and complex analog signals (operating noise) achieve expected values, and have strong resistance to dead copying, so they are particularly suitable for anti-counterfeiting verification.

In addition to the stock market of printers, the author believes that more innovative applications or business models will also be changed due to this unique fake verification scheme. For example, in the electronic semiconductor industry, some manufacturers of circuit boards may outsource the production of peripheral sub-circuit boards to authorized partners. In order to prevent peripheral sub-circuit boards from being counterfeited by unauthorized manufacturers, FRAM’s unique fake verification scheme can be used to To solve this problem, it also played a positive role in protecting intellectual property rights. It can be said that the imagination of this application will be very broad!
Mass production is hard power, Transphorm deploys GaN full-power applications
Gallium Nitride (GaN) is a third-generation semiconductor material recognized in the industry. Compared with silicon, it has many advantages, such as higher switching frequency, which can achieve breakthrough improvements in power conversion efficiency, especially suitable for power and power management. A wide range of applications. Market research firm IHS Markit predicts that the market size of power semiconductors led by GaN and SiC will approach $1 billion in 2020, driven by demand from hybrid and electric vehicles, power and photovoltaic inverters, and is expected to grow in Exceed $10 billion in 2027. Although the huge market opportunity has attracted the investment of many large manufacturers, GaN-inside products are still rarely found on the market. The reason is related to the manufacturer’s mass production capacity!
At this exhibition, Fujitsu’s agency brand Transphorm displayed several mass-produced GaNHEMT-based power application solutions, which became the focus of the audience! Yan Qinan, VP of Transphorm Asia Pacific, said: “Transphorm has invested in GaN R&D for more than ten years. Compared with other companies that have also invested in GaN, Transphorm is the first manufacturer with mass production capabilities and products to market. Therefore, Transphorm’s GaN After years of market verification, the technology continues to mature, the cost is gradually reduced, and it has excellent practicability and reliability!”
Thanks to the performance advantages of gallium nitride, Transphorm has realized a 6kW photovoltaic inverter solution with an efficiency of up to 99.2%, and a bidirectional PFC (power factor correction) solution of a 3.3kW on-board charging with an efficiency of up to 99.1%. According to the staff, this 3.3kW on-board charging solution is a totem pole bridgeless PFC solution, which has made a breakthrough in the general PFC efficiency of 97%. Due to the use of two high-performance TransphormGaN devices, there is no need to add a bridge stack to the circuit. Similar solutions of silicon devices, the overall cost is lower and the efficiency is higher. At the same time, Transphorm provides a complete set of turn-key solutions, which can deliver software and hardware together to help customers greatly shorten the development time. For example, Delta Electronics has used an on-board charging solution based on TransphormGaN devices. In practical applications, the efficiency is greater than 95%, which is a first-class level in the industry.

In addition to high-power applications, TransphormGaN devices also “show their muscles” in low-power applications. The 65W switching power supply evaluation board shown this time, at 230VACUnder full load conditions, the efficiency can reach 93%, and the standby power consumption is less than 0.15W, which is suitable for notebook computer chargers, adapters, etc. Although the size of the evaluation board is L73 x W43 x H15 mm, the staff said that if it is put into finished production, the overall solution size will be further reduced, making the size very small and easy to carry; and thanks to the high energy efficiency of TransphormGaN, this The power density of a solution is greatly improved without worrying about the heat dissipation problem in the past. Not only that, in order to meet more market demands, this solution will also support charging protocols such as PD, which can automatically adjust the current and output power of multiple levels of 5V, 9V, 12V, 15V, 20V, etc., and realize a single charger. Satisfying the charging needs of most mobile devices such as mobile phones, laptops, Bluetooth speakers, etc., brings the most obvious convenience to consumers.

Yan Qinan said: “On the whole, gallium nitride is constantly penetrating into the low-voltage, low-power consumer application market from the previous high-voltage, high-power industrial applications, which is directly related to process improvement and cost reduction. Transphorm With the existing advantages, with the help of in-depth cooperation with Fujitsu, we will seek greater breakthroughs in the Chinese market.”
The new trend of naked eye 3D, a film can be done!
At present, the new technology of naked eye 3D is setting off an industry-wide visual revolution. For example, naked eye 3D advertising is one of the directions being explored and innovated in the commercial field. It can make people feel lifelike 3D without wearing auxiliary equipment. The effect is gradually favored and sought after by electronic products, advertisements, demonstration teaching, exhibitions and other applications. According to the “Glass-free 3D Development Trend Analysis Report” released by the market research agency Sino Market Consulting, the global 3D Display shipments will reach 280 million units by 2021, and the market size will also grow to 83 billion US dollars.
In fact, Fujitsu, together with its partner 3D Global, has already invested in this field and seized the opportunity. It is understood that the innovative naked-eye 3D solution exhibited by 3DGlobal only needs to paste a customized optical 3D filter on the surface of the screen, connect an ordinary PC computer, and open the 3D video resources to achieve high-quality high-quality Naked eye 3D visual experience. Of course, this layer of special 3D filters needs to cooperate with screen manufacturers to complete the installation and debugging before leaving the factory, and then they can be sold to the market. Generally speaking, naked-eye 3D display mainly includes two technologies: light barrier type and lenticular lens, but each has its own advantages and disadvantages. 3D Global’s naked-eye 3D solution combines the advantages of the two, using the original “Lenticular Lenses + very thin parallax barrier” combination technology to reduce visual fatigue for the audience, obtain a deep 3D stereo perception, and make the picture more realistic. , while having little effect on light.
Figure 4: Fujitsu and 3D Global demonstrate innovative naked-eye 3D display technology
It is true that in addition to the innovation of hardware solutions, the market promotion of glasses-free 3D display also requires the support of constantly enriched 3D video resources. In this regard, Fujitsu can provide software tools specially used for making 3D videos for customers to understand and learn, thereby saving product development time.
