Chen Xian, vice chairman of China Semiconductor Industry Association, Chairman of Semiconductor Application Alliance Zhang Keke, and Chairman of Founder Wei Xin, were invited to attend the technical forum and deliver a speech.
Chen Xian, vice chairman of the China Semiconductor Industry Association, said in his speech that China's semiconductor industry will develop rapidly in the next five to ten years. Domestic enterprises should focus on developing top-level design, strengthening R&D and talent accumulation, and focusing on investment and building a whole industry. Chain mode.
Zhang Keke, chairman of the Semiconductor Application Alliance, talked about Shenzhen's ability to grow a large number of top semiconductor-related companies. It is precisely because of its openness and innovation that Founder Microelectronics will take root in this market.
The chairman of Founder Group Wei Xin revealed that Fangzheng Group is positively supporting Microelectronics. Chairman Wei believes that Founder Microelectronics has achieved its achievements today. It is inseparable from the support of customers and the efforts of employees. In the future, it will continue to be square. Being a man is really doing things.
Wang Heguang, president of Founder Microelectronics, said: In response to the advent of the new era of semiconductor materials, the company actively responded to the initiative of the president of Beijing University, Wang Enge, and based on the principle of “early layout and early developmentâ€, Founder Microelectronics was keenly aware in 2011. To the huge potential of the wide-bandgap semiconductor market; in July 2012, Peking University Industrial Technology Research Institute and Founder Group formally signed a cooperation agreement to establish the "Peking University Industrial Technology Research Institute Founder Group Collaborative Innovation Lab" to officially launch "GAN Power Devices" Manufacturing Technology R&D project, this project will fill the gap in China's GaN power device products.
Subsequently, Zhao Qiuqi, deputy director of Shenzhen IC Industrialization Base, and Wang Heguang, president of Founder Microelectronics, signed a signing ceremony for “Shenzhen ICC Base and FMIC to jointly build MPW service platformâ€. The two sides jointly built MPW service platform, which will be directly for Shenzhen and even South China. Regional IC design companies provide preferential subsidies and more convenient stream channels, which is of great significance.
As the world's major economies push for energy-saving and emission reduction policies, power semiconductors are receiving more and more attention from the industry. Yang Shengfan, director of the Tuoba Industrial Research Institute, said that after 2009, the ratio of output value of discrete power semiconductors to integrated power semiconductors is equivalent, and the overall growth trend is long-term. Founder Microelectronics CMO Yin Dawang believes that: 2014 power semiconductors have four major market drivers, including FPD DC/DC power supply and LED backlight, power management chip PMIC, motor drive and high voltage AC/DC drive. Strong technical accumulation.
Yin Dawang pointed out: China's LED application demand is growing rapidly during the 12th Five-Year Plan period. In particular, LED lighting is rapidly becoming the largest market for LED applications and an emerging market that FMIC expects to make an important contribution. Subsequently, the design service manager and the power integration manager gave a detailed introduction and sharing of “Green Power and LED Lighting Best Solutionsâ€.
Wu Limin, general manager of Siruida Media, said that in 2014, the output value of China's LED lighting reached 43.5 billion yuan, a year-on-year increase of 34.2%, and will maintain rapid growth in the next two years. There are already 60 to 70 driver IC companies entering the LED lighting market in China. As the market matures, the order share will be concentrated in a small number of enterprises. The resources of Foundry will be more inclined to support several large customers, so who will be in the future? Get support from upstream Foundry to gain important market voice.
Yin Dawang, vice president of FMIC Marketing, said: Founder Microelectronics' 6-inch production line currently has a monthly production capacity of 70,000 pieces. It adopts a purely foundry business model and fully protects customers' intellectual property rights from the system and model. In addition, Founder Microelectronics also provides a variety of business cooperation models, including standard process platform foundry, customized platform foundry and "virtual IDM" deep strategic partnership, which can provide customers with a very flexible and cost-effective overall. solution.
Huang Yuping, vice president of FMIC research and development, further introduced FMIC's cost-effective power management process platform from a technical perspective. Huang Yuping believes that although Founder Microelectronics only has 6-inch wafer production line and 0.4um process, it can provide customized advanced design to balance cost and performance according to customer needs, and still has strong market competitiveness. For example, the CRD scheme currently applied to LED constant current driving can only find 100V products on the market. In the view of Founder, it is very reluctant to resist 220V AC, and FMIC can provide CRD scheme up to 140V.
In addition, Huang Yuping believes that the existing 0.4um process can be further upgraded to a finer line width, but FMIC will definitely consider the competitiveness of the final product with the customer to decide whether to do it. Subsequently, Founder Microelectronics Technology Development Team also introduced in detail the competitiveness of Founder Microelectronics CDMOS800V, BiCMOS 30V, 0.5um HV CMOS process.
At present, silicon-based power devices are close to the theoretical limits of materials, and it is gradually difficult to meet the requirements of the current application market for high-power density, ultra-high frequency and harsh environments. The development of new materials will greatly expand the application range of power semiconductors. GaN wide bandgap semiconductor materials have become the first choice for new power electronic devices because of their excellent performance.
Founder Microelectronics has also begun to comprehensively deploy emerging technologies in the future. It has joined forces with Peking University, Sun Yat-sen University, China Gallium Semiconductor and TCL to build a complete GaN device application industry chain, and is determined to become a leading international supplier of GaN devices.
Shenzhen IC industry as the vanguard of reform and opening up, Founder Microelectronics is such a potential enterprise, and hope that they will grow into a "black horse" of the "national team" within three years. (This article is Founder Microelectronics submission)
The Co-Al Co-doped Barium Titanate
Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company
through repeated experiments. By Researching the influence of Co-Al Co-doping
on the structure and properties of Barium Titanate-based piezoelectric
ceramics, the formulation and preparation technology of Barium Titanate-based
piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional
solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N),
dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34.
Barium titanate lead-free piezoelectric
ceramics are important basic materials for the development of modern science
and technology, which was widely used in the manufacture of ultrasonic
transducers, underwater acoustic transducers, electroacoustic transducers,
ceramic filters, ceramic transformers, ceramic frequency discriminators, high
voltage generators, infrared detectors, surface acoustic wave devices,
electro-optic devices, ignition and detonation devices, and piezoelectric
gyroscope and so on.
