What is the maximum substrate size and batch capacity the chamber can accommodate?
Answer: The maximum substrate size and batch capacity of the chamber vary depending on the specific equipment configuration and intended application. For large-scale optics, such as telescope mirrors, the system is capable of accommodating substrates up to an impressive 2.5 meters in diameter, ensuring support for precision coating of expansive optical components. On the other hand, for semiconductor and microfabrication applications, the chamber is designed to handle silicon wafers up to 8 inches in size, allowing for efficient processing in both research and small-scale production environments. This adaptability highlights the system’s versatility in catering to a broad spectrum of substrate dimensions and industry needs.

What base and working vacuum levels are achieved in the system, and how are they maintained?
Answer: HHV Advanced Technologies (HHVAT) designs its deposition systems to achieve and maintain superior vacuum conditions, critical for producing high-quality thin films. Depending on the application, the systems can reach high vacuum levels down to 5 × 10⁻⁷ mbar and ultra-high vacuum levels as low as 10⁻⁸ mbar. These vacuum environments are made possible through the integration of advanced pumping solutions—such as turbomolecular and cryogenic pumps—combined with precise chamber sealing and optimized pumping line configurations. This ensures low contamination, excellent film purity, and stable processing conditions, supporting a wide range of materials and deposition requirements with high reliability and consistency.

What controls are available for automation, recipe management, and process monitoring (e.g., PLCs, touchscreen HMIs, SCADA integration)?
Answer: HHV Advanced Technologies (HHVAT) equips its range of deposition systems with a comprehensive suite of advanced control solutions, tailored to meet diverse process and user needs. Each system can be integrated with programmable logic controllers (PLCs) for dependable and flexible automation of complex deposition workflows. Intuitive touchscreen Human-Machine Interfaces (HMIs) offer easy navigation and real-time control, enhancing user interaction and efficiency.

This customizable control infrastructure ensures precise recipe management, process consistency, and operational safety—making HHVAT systems ideal for both cutting-edge research and scalable production environments.

How is deposition uniformity maintained across large-area substrates or multiple holders?
Answer: Deposition uniformity is a critical performance metric, especially when working with large-area substrates or multiple holders, and the system is meticulously designed to maintain excellent consistency. Through precise process control, optimized source-to-substrate geometry, and uniform distribution of the deposition flux, the system achieves a high level of uniformity, typically within ±5%. Additional features such as rotating substrate holders, planetary mechanisms, and dynamic process parameters further enhance uniform coating across the entire substrate surface. This ensures reliable and repeatable film quality, meeting the stringent standards required for advanced optical, electronic, and scientific applications.

Does the system offer in-situ monitoring tools like Quartz Crystal Microbalance (QCM) or optical monitoring systems?
Answer: Yes, HHV Advanced Technologies (HHVAT) offers its deposition systems with advanced in-situ monitoring capabilities, tailored to provide precise control and real-time process feedback. Depending on user needs, systems can be equipped with Quartz Crystal Microbalance (QCM) for accurate, mass-based monitoring of film thickness and deposition rate, as well as optical monitoring systems for dynamic feedback based on real-time optical properties—particularly beneficial for multilayer coatings and precision optics. The availability of these monitoring tools ensures greater process accuracy, reproducibility, and high-quality film outcomes, making HHVAT systems ideal for demanding thin film applications across research and industry.

What substrate heating, cooling, or rotation mechanisms are included for thermal management and film optimization?
Answer: HHV Advanced Technologies (HHVAT) equips its deposition systems with a versatile range of thermal management and substrate handling solutions, designed to deliver optimal film quality and uniformity. Radiant heating ensures precise control over substrate temperatures, enhancing adhesion and structural integrity of the deposited films. For processes involving temperature-sensitive materials, integrated water-cooling systems provide effective thermal regulation. To further improve uniformity, HHVAT systems can include advanced substrate motion mechanisms such as spherical domes, planetary rotation, and drum-type holders. These configurations ensure even exposure to the deposition source, resulting in consistent and high-quality coatings across both large individual substrates and multiple smaller ones.

What safety and interlock systems are in place to protect the operator and the equipment (e.g., vacuum lockouts, gas leak detectors, emergency stops)?
Answer: HHV Advanced Technologies (HHVAT) designs its deposition systems with a robust and comprehensive safety framework to protect both operators and equipment throughout the deposition process. Each system is equipped with essential safety and interlock features, including vacuum lockouts to prevent chamber access under unsafe pressure conditions, gas leak detectors for early identification and mitigation of hazardous leaks, and emergency stop mechanisms for immediate shutdown in case of irregularities. These features are fully integrated into the control architecture, allowing for real-time monitoring and automated safety responses. This thoughtful integration ensures safe, reliable, and uninterrupted operation across diverse applications.

Is the equipment compatible with a cleanroom environment and does it support modular upgrades?
Answer: Yes, HHV Advanced Technologies (HHVAT) designs its equipment to be fully compatible with cleanroom environments, adhering to the strict cleanliness and contamination control standards essential for precision-driven fields like semiconductor manufacturing, optics, and advanced material research.
