According to industry authorities, my country plans to include strong support for the development of the third-generation semiconductor industry in the “14th Five-Year Plan”. It is planned that during the period 2021-2025, in education, scientific research, development, financing, applications, etc., Vigorously support the development of the third-generation semiconductor industry with a view to achieving industry independence.

At present, the information related to third-generation semiconductors has been swiped in the circle of friends, but what is the third-generation semiconductor? What are its advantages and highlights? Where are its future opportunities? In Zhangjiang, which companies are related to third-generation semiconductors? Let’s get to know it together~

What is the third-generation semiconductor?

The first-generation semiconductor materials, represented by silicon (Si) and germanium (Ge), especially Si, constitute the basis of all logic devices. The computing power of our CPU and GPU is inseparable from the credit of Si.

The second-generation semiconductor materials mainly refer to compound semiconductor materials, represented by gallium arsenide (GaAs) and indium phosphide (InP). Among them, GaAs plays an important role in RF power amplifier devices, and InP is widely used in optical communication devices…

The third-generation semiconductors were invented and used in the early years of this century. Silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO), diamond (C), aluminum nitride (AlN), etc. emerged Emerging semiconductor materials with wide band gap (Eg>2.3eV) characteristics, so they are also called wide band gap semiconductor materials.

The third-generation semiconductor has the characteristics of high breakdown electric field, high saturated electron velocity, high thermal conductivity, high electron density, high mobility, and high power tolerance. It is widely used in the production of high temperature, high frequency, high power and anti-radiation Electronic devices , Used in semiconductor lighting, 5G communications, satellite communications, optical communications, power electronics, aerospace and other fields. The third generation of semiconductor materials has been considered as a new driving force for the development of today’s electronics industry.

The third-generation semiconductor belongs to the concept of post-Moore’s law, and the requirements for manufacturing process and equipment are relatively low. The difficulty lies in the preparation of the third-generation semiconductor materials, and at the same time, there must be advantages in design.

Opportunities for third-generation semiconductors

With the emergence of new markets such as 5G and new energy vehicles, the performance of silicon (Si)-based semiconductors can no longer fully meet the demand, and the advantages of silicon carbide (SiC) and gallium nitride (GaN), the third-generation semiconductors, have been amplified.

In addition, advances in manufacturing technology have led to the continuous decline in the cost of silicon carbide (SiC) and gallium nitride (GaN) devices, and the cost-effective advantages of silicon carbide (SiC) and gallium nitride (GaN) will fully emerge, which is the core growth point of the third-generation semiconductor in the future Silicon carbide (SiC) and gallium nitride (GaN) have their own advantages.

1. Silicon Carbide (SiC)

It is often used in power devices, suitable for high-voltage scenarios under 600V, and widely used in power electronics fields such as new energy vehicles, charging piles, rail transit, photovoltaics, and wind power. It is estimated that by 2023, the market size of SiC power devices will exceed 1.5 billion U.S. dollars, with a compound annual growth rate of 31%.

1.【New Energy Vehicles】

In the field of new energy vehicles, silicon carbide (SiC) devices can be mainly used in power control units, inverters, and on-board chargers. The light weight, high efficiency, and high temperature resistance of SiC power devices help to effectively reduce the cost of new energy vehicle systems.

In 2018, Tesla Model 3 adopted a SiC inverter produced by STMicroelectronics and was the first car company to integrate a full SiC power module in the main inverter. In addition, the newly launched BYD Han EV is also equipped with a high-performance SiC-MOSFET control module independently developed and manufactured by BYD.

2.[Rail Transit]

In the field of rail transit, SiC devices are mainly used in rail transit traction converters, which can greatly improve the efficiency of traction converter devices, which is in line with the development trend of green rail transit, miniaturization, and light weight.

2. Gallium Nitride (GaN)

Focusing on high frequency performance, it is widely used in base station, radar, industry, and consumer electronics fields:

1.[5G base station]

GaN radio frequency devices can more effectively meet the requirements of 5G high power and high communication frequency bands. The compound growth rate of 5G base station and fast charging is relatively fast, and it is expected to become the main driving force for the rapid growth of the GaN market. The proportion of base stations based on GaN technology will increase from 50% to 58%, bringing a large amount of GaN demand. It is estimated that by 2022, the market size of gallium nitride (GaN) devices will exceed 2.5 billion U.S. dollars, with a compound annual growth rate of 17%.

2.[Quick Charge]

GaN has the advantages of low on-resistance, low loss, and high energy conversion efficiency. Chargers made of GaN can also achieve a smaller volume. The Android side is the first to introduce GaN technology into the fast charging field. With the rapid decline of GaN production costs, GaN fast charging is expected to become the next killer application in the consumer electronics field. The global GaN power semiconductor market is expected to grow from 8.73 million U.S. dollars in 2018 to 350 million U.S. dollars in 2024, with a compound growth rate of 85%.

In September 2019, OPPO released SuperVOOC 2.0, the first domestic GaN charger, with a charging power of 65W; in February 2020, Xiaomi launched a 65W GaN charger, which is 48% smaller than the Xiaomi notebook charger and has a new low price in the industry.
