TOPPAN Test Chart

TOPPAN Test Chart is the photomask which formed the basic-shaped pattern with chromium on the high purity glass substrate.
We prepare for a positive type mask and a negative type mask.
It is available in the uses such as accuracy management of equipment, a resolution check, and a valuation basis at photoresist selection.

Photomasks for Displays

The photomask for Displays is the master mask to be used for forming a pattern on color filters.
Along with a trend towards larger and higher definition displays, photomasks are also required to be larger, with higher precision.
Toppan utilizes the ultra-fine processing technology cultivated through photomasks for semiconductors to provide a high-definition, highly reliable large-sized photomask for displays.
