INSIDE PORES

3D conformal deposition is one of the unique features of ALD. In some applications, the aspect ratios of the deposition are taken to the extreme, for example in the internal coating of aerogels and porous anodic alumina substrates. The aspect ratios can be 1:1000 or even more, with perfect uniform deposition, as shown in a presentation by one of our customers at the Max Planck Institute. These substrates can be coated either in infusion exposure mode, or in flow-through mode. Cambridge NanoTech has standard ALD systems available for these applications.

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.
