The leading metal oxide (MO) film candidate that offers up to ten-times higher electron mobility than traditional amorphous silicon (a-Si) is indium gallium zinc oxide (IGZO). The higher mobility of IGZO enables refresh rates up to 480Hz for high definition and 3D TV screens and supports smaller transistors for higher screen resolution and longer battery life. Manufacturing MO transistors requires physical vapor deposition (PVD) and plasma enhanced chemical vapor deposition (PECVD) process technologies. The IGZO film is deposited using PVD - while PECVD deposits the SiO2 dielectric film layer that protects the IGZO film from hydrogen contamination that can degrade the metal layer.
Touch panel technology captures the imagination, allowing the user to create customized and interactive experiences with the screen. Applied Materials technologies are increasing access and the diversity of applications to this technology.
Applied Materials is also exploring other potential uses for its OLED technology, especially for lighting applications. Lighting is one of the most inefficient forms of electricity used in the world today. A typical incandescent lamp uses less than 10 percent of the energy it consumes to produce light, and compact fluorescent lamps waste 75 percent of the energy consumed. OLEDs can be made on a number of substrates including flexible materials and generate light up to 10 times more efficiently than conventional bulbs.
