READ HEADS

Read heads used in magnetic recording have benefited from the pinhole free deposition of ALD grown thin insulating films. The replacement of the conventional sputter process was quick due to the film improvements and the lower cost production in ALD batch systems. Al2O3 has now been used successfully in the production of read heads for several years.

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.
