silicon carbide wafer is currently the world's most advanced third-generation semiconductor material . It is an ideal substrate for manufacturing high-temperature, high-frequency, and high-power semiconductor devices, and its research and application are of great strategic significance. In addition to the electric vehicles , 5G communications, and rail transit that we come into contact with every day, silicon carbide wafers have broad application prospects in key fields such as national defense and aerospace. Due to their irreplaceable advantages, they are regarded as the country’s new generation. An important support for the core competitiveness of information technology. It took Yang Jian and his team 17 years from the beginning of intensive research in this field to today's world-leading results.
is guided and planned by the Organization Department of the Beijing Municipal Party Committee and produced by Beijing Radio and Television Station . The country's first talent-focused documentary program " Cheers for You " will take you closer to Beijing Tianke Heda Semiconductor Co., Ltd. Yang Jian, the founder and general manager of the company .
have worked together for 17 years to build the future of the domestic semiconductor industry
A silicon carbide wafer with a diameter of 15 cm and a thickness of only 0.35 mm can depict huge information. However, the manufacturing process of silicon carbide wafers is extremely complicated. It requires heating the silicon carbide raw material to 2300°C and turning it into a gaseous state. Then, it controls various technical parameters including temperature and pressure, and finally crystallizes it to form a silicon ingot. This substrate material, which is technically difficult and accounts for half of the device cost, is regarded as a key link in the silicon carbide industry chain. There is also a saying in the industry that "the one who wins the substrate wins the world." For example, 5G is fast because it has a very powerful heart, and this heart relies on this paper-thin silicon carbide wafer.
In the past, the main production capacity of this kind of wafers was concentrated in Europe and the United States. Because other countries refused to share core technologies, the research progress of my country's silicon carbide wafers has been very slow. In the past ten years, thanks to the efforts of Yang Jianhe and his partners and Chen Xiaolong , the situation has undergone tremendous changes. In 2014, Tianke Heda finally successfully developed a 6-inch chip and put it into mass production in 2016.
Yang Jian and his partner Chen Xiaolong struggled for seventeen years from the beginning of contact with silicon carbide wafer technology to mass production and introduction to the market.
Independently cultivate talents, continuously innovate, and hold core competitiveness in hand
As the leader of a high-tech enterprise, Yang Jian has an urgent need for technical talents. Instead of discovering talents, it is better to cultivate them yourself. In Yang Jian's view, Beijing has a strong academic environment and unique scientific research advantages. Only by acquiring talents through training can it create more opportunities for itself. The Beijing Municipal Organization Department and the Daxing District Organization Department also strongly supported this, and provided Beijing household registration for the company's 5 mature talents and 15 fresh masters, and provided public rental housing for 15 people. In addition, 5 people from the company also won the title of " Daxing District New Country Leading Talent" and 6 people won the title of "Daxing District Outstanding Youth". This is the affection that talents have for Beijing, and it is also the warmth that Beijing has towards talents.
At the same time, the Daxing District Government of Beijing has provided comprehensive and multi-dimensional financial and policy support to enterprises in terms of matching funds for national (municipal) projects, transformation of major scientific and technological achievements, promotion of the development of high-precision industries, and talent training. In 2020, Tianke Heda applied for land in Daxing District, Beijing to prepare for factory expansion. Although the progress of the project has been affected by the epidemic, with the efforts and coordination of all parties in the government, the construction of the new factory has come to an end and is expected to be put into operation by the end of July this year.
Currently, Tianke Heda occupies nearly 90% of the domestic market in conductive silicon carbide wafers. This also means that Tianke Heda is fully capable of replacing foreign products to meet China's own silicon carbide wafer needs. Today, Tianke Heda ranks fourth in the world in the silicon carbide monocrystalline industry and ranks among the top in China. Hard work paid off. From following to running together and then catching up, Yang Jian finally led the team to change lanes and overtake on this entrepreneurial road.
On the road of scientific research, only by continuous innovation can we firmly grasp the core competitiveness in our own hands and have the courage to face all external challenges. Yang Jian's entrepreneurial journey is the epitome of the struggle of a generation. His down-to-earth and steady progress may be the secret weapon that keeps him going far.
Tonight (July 6) at 21:52, Beijing Satellite TV "Cheers for You" will take you closer. This issue will take you closer to the founder and general manager of Beijing Tianke Heda Semiconductor Co., Ltd.—— Yang Jian.
