Thin Film Equipment

For over five decades, HHVAT has been designing, developing and manufacturing customized thin-film deposition systems to fulfill the needs of the scientific and industrial community. HHVAT's R&D team has been closely associated with world renowned scientists in thin film technology to develop challenging and advanced thin film deposition system products. These unique thin film deposition equipments have been successfully demonstrated for functional performance, product quality and repeatability.HHVAT constantly upgrades its manufacturing capabilities to keep in-line with the evolving demands of the thin-film coating and equipment market. HHVAT manufacturing processes include engineering design, process automation, precision machining and fabrication, electro polishing, TIG welding, vacuum brazing, global supply chain, electro-mechanical assembly and comprehensive product testing.

Thin Film Technology | Thin Film Coating


HHV Advanced Technologies is ranked amongst the global leaders in thin film technology. It has a wide international market presence and is particularly strong in executing large, highly sophisticated customized thin film deposition equipment for a range of applications.

Work Holders

HHVAT manufactures a range of work holders which are designed to suit a variety of PVD and PECVD processes. The work holders have many standard functionalities such as rotation, heating and electrical biasing(RF/DC) to improve adhesion, uniformity and control film density. HHVAT also offers custom solution for substrate holders based on the sample size, geometry, throughput requirement and temperature range. 

Atomic Layer Deposition | Thin Film Technology


Options such as rotary, planar planetary, Knudsen planetary, glancing angle deposition (GLAD), and substrate flip mechanism. Substrate rotation can also be supplemented by source masking to ensure uniform depositions.

Optical Component Manufacturer | Thin Film Technology


Substrate holders can be provided with various biasing options such as DC, pulsed DC, and at alternating frequencies such as MF, RF and mixed RF and LF frequencies.

Atomic Layer Deposition | Thin Film Technology


Substrates can be heated up to 800 deg. Celsius using enclosed tubular heaters, IR Lamps, Pyrolytic Graphite, PBN or Nichrome. PID controllers ensure stable temperatures on the substrates throughout deposition.

Thin Film Coating | Atomic Layer Deposition


Provides the option to change source to sample distance up to 150mm. This feature is useful to determine optimum deposition conditions and facilitate substrate transfers between chambers.

Atomic Layer Deposition | Thin Film Technology


Load-locks allow samples to be transferred into the process chamber without it being vented. This enables the user to reduce cycle times and potential contamination of the chamber and source materials.

Thin Film Optical Coatings | Precision Optics Manufacturing


Linear transfers are available with manual or motorized actuation. These allow for in-situ transfer of samples between different chambers.

Thin Film Coating | Thin Film Optical Coatings


Specialized high vacuum compatible multi-axis robot with external teaching facility to map contours and uniformly coat complex components.
