Everything is for the national third-generation semiconductor core material research and development

Just received his PhD on the 29th, Huang Wei of the Silicon Carbide Crystal Project Department of the Shanghai Institute of Ceramics, Chinese Academy of Sciences officially entered the research work of the project department on the 30th. Like Huang Wei, in order to complete the project tasks that will be completed by the end of this year, 19 scientific researchers and 11 Ph.D. students will work normally during the May 1 holiday.

On the morning of the 30th, when the reporter arrived at the Shanghai Silicate Research Institute pilot base in Jiading District, Shanghai, Huang Weihe and the project department’s researchers were holding a project promotion meeting. Since the opening of a major national science and technology project for the development of silicon carbide crystals as a semiconductor core material last year, researchers in the project department have given up almost all holidays to step up research. Currently, more than 20 sets of silicon carbide crystal production furnaces with independent intellectual property rights have successfully produced high quality silicon carbide. Crystals.

“My colleagues advised me that if I just got a degree, I can relax for a while. But we have to finish the project at the end of the year. Now everyone is busy working overtime. How can I leave my post to rest at this time?” Huang Wei said that since undertaking this project, the R&D team has been basically unable to attend the holiday breaks, and only spent a few days off during the Spring Festival.

In a test laboratory of the project department, Liu Xuechao, director of the thin film and test team of the project department, is instructing a R&D staff to perform standard tests on finished crystal products. He said that the crystal materials developed by the project department all need to complete the characterization test on these inspection machines. “We will compare the characterization of the crystal quality according to international standards to ensure that each data is qualified.” he told According to the reporter, as the project enters a critical stage, “every day's quality testing work has almost a dozen hours, and everyone will do it on shift.”

Liu Xuechao received his Ph.D. from Shanghai Silicate Research Institute. He then went to study in the UK for two years and worked in a local research institute after graduation. “After the Shanghai Silicate Research Institute undertook the project in this country, the leadership teacher invited me to come back to join the R&D team. I think the work here is more meaningful. Although the contract there has not yet expired, I will immediately return. "The colleague who was standing next to Liu Xuechao immediately added, "Before the contract has not expired, his lover is still studying in the UK."

According to reports, when the Shanghai Silicate Research Institute undertook the independent research and development project of silicon carbide crystals of the third generation semiconductor core material of the country, many researchers working in this field were very excited and quickly combined by two related topics and became a major project. Of the R&D teams from various provinces and cities in Shanghai, Fujian, Henan, Hubei, and Shaanxi, more than 70% of them have doctoral degrees.

Yan Chengfeng, who joined the research group of silicon carbide crystals after his Ph.D. graduated five years ago, is now the crystal growth team leader of the Silicon Carbide Crystal Project. Over the past few years, he has devoted almost all his efforts to the development of silicon carbide crystal growth furnaces. Sometimes he works too late and sleeps directly in the instrument control room.

Prior to the real-time monitoring system for silicon carbide crystal growth, Yan Chengfeng introduced the use of silicon carbide crystal growth furnaces: “It is our long-term dream to independently develop a new generation of China-used crystal furnace, and we can break the technological monopoly of developed countries against us. Greatly enhance the independent research and development production capacity of China's third-generation semiconductor core materials. Now, we have mastered all the technologies from raw material to crystal growth, processing, cleaning, and testing until users can produce semiconductor products.”

Yan Chengfeng stated that during this period of busy work, he basically ignored his family. “Fortunately, the lover can understand my work. In fact, the colleagues in our team are basically married. Everyone now wants to finish the task and sacrifice. A little personal stuff is nothing, everything is for the country's third-generation semiconductor material research and development as soon as possible."

Coaxial Cable is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The termcoaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line.
