Taiwan-based Efun Technology, a manufacturer of critical components for touch screens, LCD monitors and backlight modules, has started to produce flexible substrates coated with indium tin oxide (ITO) films for touch panel screens. The ITO films were deposited using a SmartWeb system from Applied Materials, according to the equipment supplier.
This is the second SmartWeb system Efun has purchased from Applied for manufacturing its ITO touch panel components, the equipment maker indicated. The first system has been in production at Efun since 2009.
Applied's SmartWeb system is a roll-to-roll vacuum coater that uses physical vapor deposition technology to deposit the ITO-based multi-layer film stack required for fabricating the most advanced touch panels used in tablet PCs and other mobile devices, the company said.
"The latest generation of tablet PCs features 7-inch and larger projective capacitive touch screens, sizes that demand the highest quality and performance from the ITO substrate. Applied Materials was able to meet our technical specifications and aggressive timeline, providing the technology to meet our customers' requirements for high-end touch panels at a price that enables them to successfully compete in a demanding consumer market," said Kuang-Rong Lee, vice general manager, optoelectronics business unit leader, at Efun.
