Large-size conductive glass/ glass substrate
Large size conductive glass substrate is developed by patterning the low resistance copper film on the glass.
Pattern could be formed on the large size glass substrate of 730mm×920mm at maximum.
Applications such as large size printed circuit boards and large size glass sensors are expected.
Features
- Pattern is formed on the glass substrate using copper with low sheet resistance.
- Processing of large size glass substrate possible
→ 730mm×920mm at maximum
