Glass wafer is thin discs of precision glass, made of borosilicate, fused silica, glass, and quartz. It is essential for display engineering and display glass inspection systems. Also, glass wafer is used as a substrate carrier for bonding silicon or other substrates, for Micro Electro Mechanical Systems (MEMs).
Glass wafer is superior to the regular substrate in certain aspects. While being more cost-effective, it has better wrap management and less electrical loss. The glass wafer market is expected to grow further since its related industries like IoT are rapidly expanding.
