Semiconductor: Practice Environmental Protection with Innovation

Among the many science fiction works, most of the descriptions come from the embarrassment of the future world. People use various convenient and clean energy sources, which are highly efficient, clean and efficient, and may even be completely free of energy. However, in the foreseeable future, we will also rely on the most widely used and energy-conversion-electric energy. Although current electronic devices are moving in the direction of green and low energy consumption, the pollution generated by petrochemical energy sources has become more and more important. With this trend, it is possible to reduce the circuit loss in electronic devices and increase its power utilization rate.

The operation of power semiconductors is between weak current control and high power, and it is second only to large-scale integrated circuits. Each electronic product cannot be separated from power semiconductor technology. The purpose of power semiconductors is to make electrical energy more efficient, more energy-efficient, more environmentally friendly, and to provide users with more convenience. Such as through the frequency conversion to speed, so that the inverter air conditioner in the energy-saving 50-70% at the same time, more environmentally friendly, more quiet, more comfortable. In the field of portable electronic products, CPU and display technology have advanced by leaps and bounds, but the capacity of the battery has not been greatly improved, resulting in various contradictions in portability and single-use time. Consumers want phones and tablets to be used longer after a single charge. Therefore, in the electronic equipment, the energy saving function of the power semiconductor starts to take effect. From the perspective of the terminal, energy saving and carbon emissions are optimized.

With the establishment and promotion of green environmental protection in the international arena, the application of power semiconductors has expanded from the traditional industrial control and 4C industries (computers, communications, consumer electronics and automobiles) to new energy (wind, solar energy) and orbits. New areas such as transportation and smart grid.

Compared with digital integrated semiconductors such as microprocessors and memories, the product life cycle of power semiconductors is relatively long, which can be several years or even more than ten years; at the same time, power semiconductors do not pursue the rapid reduction of feature sizes and do not require the most advanced production technology. The cost of its production line is much lower than the VLSI constrained by Moore's Law. Therefore, power semiconductors are very suitable for the current situation of China's industries and China's energy tension and build a harmonious society.

The growth of power semiconductors mainly focuses on new industries such as LED lighting, electric vehicles, and new generation communications and cloud computing, which will become new economic growth points.

The low energy consumption and high luminous rate of LED lighting products make LED an important area of ​​concern in the lighting field. As with LEDs, power semiconductors are on the same road, and the outcome of the two will be closer in the new year. Other electric cars and cloud computing and other products that have been separated from petrochemical energy will also lead to the development of power semiconductors.

In 2015 and beyond, the power semiconductors will play a more important role in the electronics field. There will be more and more opportunities in the city. In the establishment and promotion of the international status of green environmental protection, the use of power semiconductors will also be expanded from the electronic products, industrial control, lighting and other fields mentioned in the text to wind power, solar photovoltaic, smart grid and other fields.
