LEDinside conference Watch: SEMI Power Electronics Conference to foresee the market blue ocean

With the global energy saving and environmental protection, sustainable management consciousness, photoelectric semiconductor industry more actively developing innovative technology to improve product efficiency, reduce power consumption and reduce the material and simplify the process, plus electric vehicles and renewable energy and other energy conversion and transmission system for high efficiency and low power design demand, prompting industry to look for silicon carbide (SiC) and gallium nitride (GaN) can support higher power conversion materials.

Optimistic about this trend, SEMI on October 14th at the Sheraton Hsinchu Hotel organized "power electronic technology seminar", GaNSystem, Delta, Yole invited Toyota and other industry technology pioneer, for silicon carbide and gallium nitride power components, compound semiconductor, automotive semiconductor materials and other topics, from the upstream process to the terminal application, to share the latest trends and technologies.

Yole Development Pierric Gueguen said the benefit from the high speed power market and energy saving, green market demand, the power module market will show a rapid growth trend. The main opportunity lies in the market for power density and conversion efficiency requirements, but the challenge lies in its price and cost. In terms of power density, high current density, high operating temperature and instant switching capability are required. In efficiency, but also to see the heat dissipation capacity will be the most important indicators of power package. Due to the high power density requirements, the operating junction temperature at 150 DEG C products can be more efficient and high performance. Vendor layout, the acquisition of Infineon WolfSpeed synergy, I believe the market share will be able to grow more quickly.

To sum up, it is expected that in 2020 the development of products, GaN power components will be able to achieve the performance of 900V; and SiC power module products will be able to upgrade to a higher pressure market. In product applications, GaN power module is more suitable for power supply products; SiC power components are used in the industry to be a stable performance of the market, to achieve higher 1700V product applications.

GaNSystems senior marketing director Charles Bailley said that in terms of heat dissipation coefficient, SiC power products have excellent performance. In addition, GaN products are quite suitable for fast switching, heat dissipation, and PCB circuit design (Layout), providing small volume product design. Therefore, the future will be more suitable for GaNE-HEMT to replace SiMOSFET and IGBT and other products on the market, such as AC-DC power supply used in consumer products and Information Center (DataCenter), market and industrial enterprises solar inverter, vehicle market application etc.. Finally mentioned in GaNE-HEMT and SiMOSFET on the quality factor comparison (FigureofMerit, FOM), GaNE-HEMT has a higher current distribution from 7A to 250A. Finally, I believe GaNE-HEMT under test index of the JESDE industry standard, product development design more clear, also in the car at the same time for product testing, the future will be more to promote the product specification from the pointer, and then drive the market demand.

Epiworld was founded in 2011, focused on SiC Lei chip growth, the main size of 3, 4, 6 inch product. In addition to the production of products, Epiworld is looking forward to common and customer service to provide assistance. With 4 inches of products, thickness consistency and stability can reach a certain index.

Mr. Feng Gan pointed out that the current EpiWorld epitaxial growth is mainly in the 4H-SiC substrate, but the price of the substrate is quite high. At present, the mainstream of the market to 4 inches, in order to improve the cost of production, towards the development of 6 inch products. However, 6 inch products face to supply challenges. First, the market demand is growing steadily, but not to need to raise supply steps; second, product quality is not stable; third, with product size, facing manufacturing stress is relatively challenging.

Delta technology officer Dr. Zhang Yuming pointed out that the industrial robot with 4 high speed motor driven by market demand, the past use more IGBT, but the future in efficiency and better performance on the GaN and SiC power components will be more attention. At the same time, it is also expected that the famous car factory in Europe will launch electric cars, driven by rapid charging market demand.

Power module products in addition to high power requirements, but also requires high input voltage, in order to achieve renewable energy, smart grid market requirements. At the same time, the volume and weight of the product must also be up to Ownership (Total Cost of), and high frequency module has become the main trend.

Meanwhile, compared to IGBT, SiCMOSFET has better low conduction loss (Lower Conduction Loss) with low switching losses (Lower Switching Loss). Considering the power module design, in addition to reliable givers, reduce the stray inductance and capacitance (Stray Inductanceand Capacitor) is very important, and the product design covers the gate drive current protection (GateDriveCircuit) (Protection Circuit). At the same time, the introduction of more suitable package will help the product to be used in the market. If there is a cloud monitoring system to help improve the working life and reliability, but also quite in line with market demand.

Zhang Long mentioned, used in SiCMOSFET power module package used in the electric car market, Fuji's latest products with 6 switches, two parallel, with constant voltage, overvoltage protection cover, will consider the market demand.

Toyota Motor Corporation (Kimimori Hamada) served as minister Hamada Komori proposed, currently there are 9 million sets of TOYOTA hybrid vehicle (Hybrid Vehicles), with the future of the fuel consumption standard is more stringent and reduce carbon emissions requirements, TOYOTA's own set of vehicle zero carbon emissions in 2050. Due to the attendant requirements, I believe that the electric car market will become
