Third generation semiconductors have recently attracted much attention

01

Xiaomi, Transsion and other companies are seizing the opportunity to apply third-generation semiconductor materials to the fast charging field; In the capital market, upstream and downstream companies of third-generation semiconductors such as Taiji Corporation, Antai Technology, Luxor Technology, and Haite High tech have shown active performance. At the policy level, there are reports that the domestic semiconductor industry will receive coordinated development, and the support for industry development will be further increased, with particular emphasis on third-generation semiconductors

In the view of industry experts such as Kunshan, Secretary General of the Third Generation Semiconductor Industry Technology Innovation Strategic AllianceVigorously developing third-generation semiconductors is of great significance, especially in supporting carbon peaking and carbon neutrality.

-UV LED chip packaging-

The third-generation semiconductor, also known as wide bandgap semiconductor, represented by silicon carbide and gallium nitride, has superior properties such as high frequency, high efficiency, high power, high voltage resistance, high temperature resistance, and strong radiation resistance.

It is a key core material and electronic component supporting the independent innovation, development, transformation and upgrading of new generation mobile communications, new energy vehicles, high-speed rail trains, energy Internet and other industries

-Suzhou Extension Center-

According to Cai Wei, a member of the China Electric Vehicle Hundred People's Association and a professor at Harbin Institute of TechnologyThe inherent characteristics of third-generation semiconductor power chips and devices determine their advantages in efficient energy conversion in industrial manufacturing, household appliances, and other fields

An emerging intelligent and environmentally friendly industryThe industry urgently needs third-generation power semiconductors that are high-frequency, efficient, and temperature resistant. ”Cai Wei said

How to better develop third-generation semiconductors and help achieve carbon peak and carbon neutrality goals

Yu Kunshan believes that the first step is to achieve industrialization of key materials, core chips, and modules, optimize the layout of the industry, and implement demonstration and large-scale applications

Specifically, in response to the demand for third-generation power semiconductor devices (silicon carbide and gallium nitride material systems)Accelerate the independent and controllable development of the entire third-generation semiconductor industry chainThis includes: achieving mass production of high-performance 6-inch and 8-inch silicon carbide single crystal substrates and epitaxial materials and their power devices as soon as possible, mass production of 6-inch and 8-inch silicon-based gallium nitride epitaxial materials and their power devices, mass production of high-performance packaged devices and modules, and localization of core testing instruments and equipment for single crystal substrate growth, processing, chip technology, packaging, testing, etc

-Layout of UVA/UVC LED Industry Chain-

In addition, Yu Kunshan suggested that while encouraging local governments and social capital to actively participate in the industrialization of third-generation semiconductors, the characteristics of the semiconductor industry such as high technological barriers and long cycles should be taken into account, and the industrial layout should be promoted in an orderly manner

In regions with a solid semiconductor industry foundation, strong financial strength, and abundant talent reservesGather in the industrial chainWe will first lay out the upstream and midstream industries in order to quickly achieve the industrialization of core materials and chips. Then, with mature teams and enterprises as the core, we will carry out mass production and expansion on a larger scale, and finallyPromote and apply mature technologies and products of third-generation semiconductors to various industriesYu Kunshan said

-Own research and development, packaging, and production facilities-

Cai Wei also emphasized the need to strengthen the construction of the industrial chainRealize low-carbon or even zero carbon strategies throughout the entire lifecycle, from substrate, epitaxy, chip to packaging, controller design and manufacturing, and applicationThe independent and controllable raw materials, chips, and devices are the cornerstone of the healthy development of the third-generation wide bandgap power semiconductor industry, and also the guarantee for the implementation of the dual carbon strategy goals throughout the entire industry chain

-UVA LED printing curing-

-UVC LED sterilization home appliances-

On this basis, Qiu Yufeng suggests promoting the integration of research and application, and conducting application demonstrations in downstream fields such as white goods, consumer electronics, logistics, and new energy.  Through application demonstrations, help equipment manufacturing enterprises become familiar with and master third-generation semiconductor devicesAccelerate product iteration, open up market application demand channels as soon as possible, and accelerate product maturity.
