200 mm diamond monocrystal produced for the first time

Diamond Foundry announced that it has produced the world's first 200 mm diamond monocrystal. The diameter of the crystal corresponds to 8 inches. The company announced this achievement on November 5. Therefore, the development is being closely watched for the future of rhinestone in the semiconductor industry.

Why is 200 mm diamond monocrystal important?

As the size of the crystal increases, its surface area also increases. Therefore, the space of the material can be used more efficiently. Additionally, production performance is expected to increase. However, this expectation is based on the statements in the announcement for now.

So 200 mm diamond monocrystal can accelerate the widespread use of artificial diamond in the semiconductor industry. Because the size of the plates used in chip production plays a big role in terms of cost and efficiency. Therefore, the 8-inch diameter can be seen as an important threshold in this field.

Valuable properties of diamond for electronics

Diamond has many properties that attract the attention of the electronics world. First, let's briefly look at these features:

Ultra-wide band gap: A feature that allows the material to operate stably at high voltages.

High charge carrier mobility: It means that electric charges can move quickly within the material.

High refractive field strength: In addition, the material can withstand strong electric fields.

Very high thermal conductivity: Thus, it can dissipate heat quickly.

Thanks to these properties, diamond is considered a promising material for power semiconductors. It can also be used in chip cooling systems. For example, its ability to dissipate heat quickly gives diamond an advantage in this area.

When the wide band gap and high refractive field intensity are considered together, the picture becomes even more interesting. Because the material can withstand both high voltage and strong electric fields. That's why the interest in diamonds in power electronics is increasing.

Can also be used in optoelectronics

Diamond transmits light well. Moreover, its refractive index is also high. For this reason, it is considered a material suitable for use in optoelectronic devices.

Therefore, 200 mm diamond monocrystal could open a new door not only for power semiconductors but also for light-powered electronics. However, these possibilities remain at the theoretical level for now.

Diamond Foundry's announcement does not include a commercial production schedule or price information. The 8-inch crystal, which the company announced on November 5, only represents a new threshold in production size for now.
