Meiden Establishes World's First Technology for Manufacturing Flexible Barrier Film at Moderate Temperature Using Pure Ozone
TOKYO, May 15, 2018 /Kyodo JBN-AsiaNet/ --

Meidensha Corporation (hereinafter Meiden) has established the first technology 
in the world for barrier film deposition at a moderate temperature using 100 
percent pure ozone, which is expected to cut drastically the cost of making 
bendable displays and electronics, the company said.

Tokyo-based Meiden has been developing the technology in collaboration with the 
National Institute of Advanced Industrial Science and Technology (AIST) since 
2000 and applied for a patent in March 2018.

This technology could be used for high-performance film for flexible organic 
electroluminescent (EL) displays, printed electronics (PE) and flexible 
electronics. At present, plasma technology is used to manufacture flexible 
organic EL displays, but it requires high temperatures of 100 C to 150 C. 
Meiden's new technology enables film deposition to be performed on resin film 
at 30 C, which is expected to significantly lower energy costs.

"Pure ozone is effective in producing nanometers-thick film with less energy," 
said Kazuhiko Murai of Meiden's Engineering Business Unit. "It also could 
shorten the manufacturing process because it could allow a single machine to 
perform the multiple tasks of film deposition, surficial hydrophilic 
enhancement and removal of organic materials generated during manufacturing." 

Meiden and AIST have jointly developed a device to continuously generate pure 
ozone. Meiden is the only maker that can produce the device, which is mainly 
used for manufacturing semiconductors.

Meiden plans to continue its research partnership with AIST to improve the 
quality of film that is precise, difficult-to-scratch and bendable with 
excellent barrier properties. These types of film are expected to have many 
future applications.
