The photomasks produced by Finex are for the high precision industry

Photomasks are produced by forming delicate 2–3µm patterns on the glass board. Customers use our photomasks to produce flat panel displays similar to liquid crystal. Flat panel displays such as liquid crystal and plasma are widely used for TVs, PCs, mobile phones and in-vehicle screens.

SK-Electronics, the parent company of Finex, has been actively developing technologies to meet large-size, high-precision demand since 1980s. In recent years, SK-Electronics has been able to provide 1 m2 large photomask for the 10th generation LCD panel.

The photomasks produced by Finex are primarily for TFT (Thin-Film Transistor) and CF (Color Filter).


・TFT (Thin-Film Transistor)

It is one of the liquid crystals formed by thin-film transistors. It is a transistor on a glass substrate formed by a-Si, LTPS and IGZO. It can be used for LCD panels.


・CF (Color Filter)

In order to display color on the LCD, pigment is added to the resin film, which is one of the ingredients of the liquid crystal component. Patterns in red, green and blue will then formed orderly on a transparent glass substrate.
