Diamond Wafer

Avilable sizes- 1”- 6”

Applications of Diamond Wafers:

1. Semiconductors & Electronics – Used as a heat spreader or substrate for high-power electronic devices.
2. Optics & Lasers – Utilized in infrared and high-power laser windows.
3. Cutting & Grinding Tools – Employed in precision machining for its extreme hardness.
4. Quantum Computing – Used in diamond-based quantum sensors and computing.

1. Monocrystalline Diamond Wafer

• Made from a single continuous crystal of diamond.
• Has a uniform structure with no grain boundaries.
• Offers higher purity, thermal conductivity, and mechanical strength than polycrystalline wafers.
• Used in semiconductors, optics, and quantum computing.
• More expensive due to the complex growth process, typically done using chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT) methods.

2. Polycrystalline Diamond Wafer

• Made up of multiple diamond grains fused together.
• Contains grain boundaries, which may slightly reduce thermal conductivity and strength compared to monocrystalline.
• More cost-effective and easier to manufacture in larger sizes.
• Commonly used in cutting tools, heat spreaders, and industrial coatings.
• Typically produced using chemical vapor deposition (CVD).
