Diamond is known as the fourth-generation semiconductor material, and its performance far exceeds traditional third-generation semiconductor materials such as silicon (Si), silicon carbide (SiC) and gallium nitride (GaN). Compared with other semiconductor materials, diamond wafers have significant advantages in the following aspects:
Ultra-high hardness: Diamond has a hardness of up to HV10000, which is the hardest known material, making it exhibit excellent wear resistance in extreme environments.
Ultra-fast thermal conductivity: The thermal conductivity of diamond is as high as 22W/(cm·K), far exceeding Si (1.5W/(cm·K)), SiC (4.9W/(cm·K)) and GaN (2.3W/(cm·K)), which can greatly reduce the difficulty of thermal management of high-power devices and improve system stability.
Wide bandgap: Diamond has a bandgap of about 5.5eV, which is higher than Si (1.1eV), SiC (3.3eV) and GaN (3.4eV), making it suitable for high-temperature, high-frequency and high-power applications.
High electron mobility: Diamond has excellent electron and hole mobility, which makes it excellent in high-speed electronic devices and microwave power amplifiers.
With these advantages, diamond wafers show great application potential in high-power electronic devices, high-frequency microwave communications and advanced computing.
Currently, single crystal diamond wafers have been used in many high-precision fields, mainly including:
Quantum communication and computing
The nitrogen-vacancy (NV) center in diamond can be used as a quantum bit (Qubit) and play a key role in quantum computing and quantum communication technology. Its long spin coherence time makes it an important material for future quantum computers.
Radiation detectors
Due to the high energy band gap and excellent radiation resistance of diamond, it can be used to manufacture highly sensitive radiation detectors, which are widely used in nuclear energy monitoring, aerospace detection and high-energy physics experiments.
Semiconductor lasers
Diamond's high thermal conductivity makes it an ideal substrate material for high-power semiconductor lasers, which can effectively improve the power density and service life of lasers.
Cold cathode field emission display (FED)
Diamond's negative electron affinity (NEA) property makes it a cold cathode electron emission material, which can be used for high-efficiency and low-power field emission displays (FED).
High-power microwave devices
In the fields of military high-power radar, microwave traveling wave tubes (TWT) and satellite communications, diamond wafers can be used as substrate materials for high-frequency and high-power microwave power amplifiers to improve the heat dissipation performance and working stability of the system.
Supercomputer CPU chips
The high thermal conductivity and stable electronic properties of diamond wafers make them a potential candidate material for future high-performance computing (HPC) chips.
Multidimensional Integrated Circuits (3D ICs)
The excellent heat dissipation performance of diamond wafers can provide efficient thermal management solutions for 3D stacked chips, reduce power consumption, and increase computing density.
With the growing demand for high-power, high-frequency, and high-temperature devices in the semiconductor industry, the diamond wafer market is ushering in a period of rapid development.
