Foundry service for High-quality film devices

Nissha manufactures patterned electrodes and functional layers on thin films which are comprised in various film type devices. We provide consistent support for our customers from prototype development to mass production.

Roll to Roll mass production process

Mass production capability with Roll to Roll film process up to 500mm width is our strength. We can handle flexible films up to 500mm width with various patterning proccesses and module fabrication.

Key Features

  • Plastic substrate;
    PET , COP , PC ,PI etc. (50 – 250 µm thickness)

  • Metals and oxides;
    For etching process: Copper, ITO, Copper alloys, etc.
    For screen printing: Ag paste, carbon paste, etc.
    We also make a pattern on silver nanowire conductive layer.

  • Minimum Line/Space;
    Photoetching process: Line/Space=10um/10um (Capable of double sided patterning)
    Screen printing process: Line/Space=50µm/50µm

  • Size;
    Web width : 500mm
