HKH Tech Stack

At HKH Technologies, we've meticulously engineered a comprehensive suite of advanced technologies to produce and integrate single-crystal diamond wafers into semiconductor applications. This proprietary tech stack is exclusively utilized within our operations, ensuring unparalleled quality and performance.

1. HKH Wafer Heteroepitaxy

Creating wafer-sized single-crystal diamonds necessitated pioneering efforts, as such crystals were previously nonexistent. Our team employs a sophisticated technique known as diamond heteroepitaxy, enabling the formation of single-crystal diamond layers on scalable substrates. This process involves precise control at the atomic level, facilitating the growth of flawless diamond structures.

2. HKH Ingot Growth Reactor

Our reactors have evolved through ten generations, each iteration enhancing quality, yield, and efficiency. By refining plasma configurations, we've achieved optimal conditions for diamond synthesis. Our reactors address challenges such as erosion, overheating, and nitrogen contamination, ensuring the production of superior single-crystal diamonds. We collect over a billion data points per carat during production, utilizing cloud computing to analyze and adjust growth parameters in real-time.

3. HKH Wafer Singulation

Slicing single-crystal diamond ingots into wafers presents unique challenges due to diamond's exceptional hardness. Our engineering team has developed specialized equipment, the HKH Wafer Singulator, capable of efficiently and precisely cutting diamond ingots into uniform wafers suitable for semiconductor applications.

4. HKH Wafer Finishing

Achieving semiconductor-grade surface flatness on diamond wafers is critical for device integration. We've developed cost-effective polishing techniques that attain atomic-level flatness over large areas, meeting stringent industry standards and enabling seamless integration with other semiconductor materials.

5. HKH Chip Bonding

Integrating diamond wafers with various semiconductor chips, including silicon, silicon carbide (SiC), and gallium nitride (GaN), requires advanced bonding techniques. Our proprietary methods establish direct atomic connections between chips and diamond substrates, effectively eliminating thermal dissipation bottlenecks and enhancing overall device performance.

Through this comprehensive tech stack, HKH Technologies is at the forefront of innovation, delivering high-performance diamond-based solutions that redefine the capabilities of modern semiconductor devices.
