After the new product launch, the "Silicon Power Salon" lecture was held. Zhang Bo, director of UESTC PITEL, and Zeng Zefu, chief expert of Chengdu Star Source, and Jesse Parker, general manager of Chengdu Silicon Power Technology, gave speeches respectively.

Professor Zhang Bo’s speech is “Power Super-Junction Device”. Zhang Bo pointed out that in the development of power devices, breakdown voltage and on-resistance are contradictory. In the late 1980s, high-voltage power MOS tubes reached a bottleneck of growth. The on-resistance was limited by the breakdown voltage, and could not be reduced any lower. The performance improvement of high-voltage silicon devices encountered a "ceiling". In order to break through this limit, many new structural devices continued to emerge. In the late 1980s and early 1990s, a new concept broke this "ceiling". After the concept was evolved and improved, the "super-junction theory" was formed. Super-Junction metal oxide field effect tubes use Charge Balance to make Rsp and BV close to a linear relationship instead of a 2.5 exponential relationship. It breaks the theoretical pole of traditional power MOSFET devices and is internationally known as "a milestone in the field of power MOSFET devices." Using the super-junction theory, both low on-state power consumption and high switching speed can be obtained. The typical product of the early application of super-junction theory was the "COOLMOSTM" device introduced by Infineon of Siemens in Germany in 1998. The revolutionary breakthrough of the "COOLMOSTM" product introduced at that time was: in the scope of its work, compared with traditional technology, the on-resistance of the same chip area is reduced by 80%-90%, breaking the silicon limit and having a high switching speed. Super-junction technology is not only a process, but also a structure. In the 1980s and 1990s, Europe, America, Japan and other countries proposed three super-junction technologies through different methods and applied for patents before application.

Super junction structures have become an important trend in the development of semiconductor power devices. When using high-voltage and high-power MOSFET, the driving power of the front stage can be reduced, thus the power consumption of the device can be reduced. The power conversion efficiency is excellent. The efficiency of the whole machine is improved, and the energy consumption is reduced to become environment-friendly. Compared with traditional planar high voltage power MOSFET devices, high voltage super junction power MOSFETs are characterized by small size, low on-resistance, high load drive capability, low temperature rise in power devices, high reliability levels, and long operating life. At the same withstand voltage, the allowable operating frequency is higher, and the operating current required for the gate is small. Under the condition of the same terminal power requirement, a high-voltage super junction power MOSFET device with a smaller package can be used. The power converters produced by high-voltage super-junction power MOSFET devices have greatly improved energy efficiency and are an advanced structural device that completely replaces traditional planar process high-voltage power MOSFET devices.

In response to questions from the scene, Zhang Bo said that wide-bandgap semiconductors such as SiC and GaN will be an important trend for semiconductor development. In consideration of performance, cost, process and other factors, for a long period of time, BB, GaN and other wide band gaps semiconductors have not completely replaced traditional silicon-based semiconductors. As a result, traditional silicon-based semiconductor products and emerging wide-bandgap semiconductors such as SiC and GaN should complement each other and develop a relationship.

Jesse Parker, the general manager of Chengdu Silicon Power Technology introduced the semiconductor entrepreneurship course he planned by himself. Mr. Jesse Parker is an American. He has been in China for 25 years. He has served as an executive in well-known multinational companies such as IBM, Softbank, and Shanghai Advanced Semiconductor.

He has a wealth of business management experience and the most practicable entrepreneurial skills theory. Starting from this "Silicon Power Salon", Mr. Jesse Parker will introduce the entrepreneurial guidance series, and will share the experience and knowledge accumulated over the years to the audience of the salon. Jesse Parker said that the Silicon Power Salon lecture in the second half of the year will be divided into two parts: entrepreneurial knowledge and skills and semiconductor design and manufacturing technology. The topics identified in the entrepreneurial knowledge and skills section include investment knowledge and experience from the initial stage of semiconductor investment, important legal matters during the startup phase and semiconductor IP protection and patent review, semiconductor investment opportunities in VC investors’ vision, the role of PE investment in the initial development of semiconductor companies, and ways to successfully attract national big funds and bank investment. The topics identified in the Semiconductor Design and Manufacturing Technology are Tape-out & MPW processes, selection and use of EDA tools, chip packaging and testing technologies, discrete device and IC reliability tests, wide bandgap semiconductor device performance, and manufacturing process and applications.

Zeng Zefu, chief expert of Chengdu Star Source gave a speech on "NB-IOT RF Front-End Design and Testing". Zeng Zefu pointed out that the Internet of Things has penetrated into all walks of life. The era of Internet of Everything is entering our lives at an extremely fast speed. NB-IOT means narrow-band Internet of Things. It has become the most important technology in the Internet of Things wireless technology depending on its advantages of wide coverage, low power consumption, large connection and low cost. The number of NB-IOT base stations has reached 1.1 million by the end of 2018, and the number of NB-IOT base stations is expected to reach 3 million by 2025.
