The world's first 100mm diamond wafer appeared

Recently, the headquarters is located in San Francisco, CaliforniaDiamondfoundryin announced the manufacture of single -crystal diamond wafer with a diameter of 100 mm in the world.

The company plans to provide diamond -based boards as a way to improve thermal performance, which in turn can improve artificial intelligence computing, wireless communication, and smaller power electronics equipment.

The company uses a process called heterogeneous extension to deposit carbon atoms and manufacture single crystal diamonds on scalable bases.It has been produced by diamond chips before, but it is based on compressed diamond powder and lacks the characteristics of single crystal diamond.

Diamond Foundry said that its next goal is to reduce the deficiency density of diamond wafer to achieve a quality factor of 17200 times higher than SI and 60 times higher than SIC.

at present,Diamond Foundry runs a diamond and wafer production plant in Washington.

It is reported that the company was established inIn 2012, the business involved jewelry and luxury markets and semiconductor industries.The company stated on its Linkedin website that it has received $ 515 million in financing and is implementing a billions of dollars to expand plans to transform greenhouse gas into diamond SI films with zero -emission energy.

According to them, the company can adhere to the integrated circuit that has been dumped in the accuracy of Music level by atom. (IC) Wornes, the final thermal chip packaging is implemented.

From the perspective of heat -guiding, no other materials can effectively conduct heat like a single crystal diamond, so that the chip runs faster and has a longer service life.This provides a hot highway within the atomic distance of the diamond wafer in the atomic distance of the working chip crystal tube.It cools heat at ideal efficiency, reduces hot spots and increases the computing speed of the chip.

At the same time, this is still an extreme electrical insulation. The thinnest diamond section can beolate very high voltage, so that the miniaturization of the electrical electronic devices reaches a new level.

Thanks to these leading characteristics,Diamond Foundry认为公司的解决方案适用于所有领先的高功率芯片，经过验证的硅芯片与金刚石半导体基板的结合极大地加速了云和人工智能计算，这意味着使用数据中心一半的空间即可获得相同Performance.

These advantages also allow them to simplify the inverter design, which will make novel architecture fundamentally promote miniaturization, efficiency, and robustness because of the thermal conductivity of diamond wafer and the extreme characteristics of electrical insulation.

This leading design also allows it to help in the field of wireless communication.

According to reports,GAN semiconductor provides motivation for more and more effective wireless communication.But King Kong stone wafer solves the problem of overheating and voltage, making GAN better than SIC on each indicator.The power density of the diamond -based GAN MOSFET is three times that of GANs without diamonds.By reducing the thermal stress and connecting the GAN atom into DF (Diamond Foundry) single crystal diamond, it improved reliability.

Similar company Diamfab SA (Glernobul, France) was established in Europe in 2019.DiaMFAB synthesizes and is doped on the extension of diamonds growing on other substrates, in order to make it with diamondssuperiorPower device.
