LAYER ATOMS

Cambridge NanoTech manufactures Atomic Layer Deposition (ALD) systems for many coating applications. ALD is used to deposit thin films with exceptional qualities. A large number of standard materials are available.

The principle of ALD is based on sequential pulsing of special precursor vapors, both of which form about one atomic layer each pulse. This generates pinhole free coatings that are perfectly uniform in thickness, even deep inside pores, trenches and cavities.

Join the market leader with 96+ systems sold.

ALD is suitable for many applications in Semiconductors and nanoelectronics including Gate Dielectrics, Gate Electrodes, Diffusion Barriers, and DRAM | Dynamic Random Access Memory. In the optical fields, ALD can be applied to Optical Dielectric Multilayer Structures / Filters, OLED (Organic Light Emitting Diode), Photonic Crystals and static Photonic Band Tuning, Transparent Conductors and Transparent Conducting Electrodes, TFEL or Thin Film Electroluminesence, Solar Cells, OLED Humidity Barrier, Precision Optics Coatings and Photonic Crystal Structures and Lasers. ALD is also applied to MEMS (micro electromechanical systems and Hydrophic & Anti-Stiction Layers in MEMS Devices. There are also applications of ALD in wear resistence, in coatings for blade edges and Nanocomposite Tungsten Disulphide solid lubricants. ALD is also used in nanostructures such as nanotubes & nanowires, and Atomic Force Microscope (AFM) tips. Other common applications of ALD are Catalysis & Catalyst Supports, Solid Oxide Fuel Cell Electrodes, Nano Glue, Biocompatible Coatings for medical instruments Ferromagnetic Transition Metals & Nanotubes and Internal Tube Liners and Inert Inner Linings.
