Glass Wafer

Applications of Glass Wafers in Display Technology

Glass wafers are widely adopted in display‑related applications. Display‑grade glass wafers are mainly used as substrates for LCD, OLED and other display technologies. For instance, diced display glass wafers are fabricated into AR waveguide lenses for Augmented Reality (AR) devices.

Applications of Glass Wafers in Semiconductor & IC Packaging

Glass wafers also play a vital role in semiconductor and integrated‑circuit packaging. Fused‑silica glass wafers are extensively deployed in semiconductor and optical industries for manufacturing sub‑wavelength pigment filters for visible‑light spectrum. Besides, glass wafers act as substrates for diverse IC packaging solutions, delivering improved performance and cost‑effectiveness.

Applications of Glass Wafers in Biotechnology & Sensors

Glass wafers are of great importance for biotechnology and sensor applications. Borosilicate glass, a premium option for medical‑grade glass, is applied in X‑ray equipment. Glass wafers are also used for integrated bio‑chip systems, as well as constructing thermo‑responsive surfaces for enzyme‑free cell harvesting.

Applications of Glass Wafers in MEMS Packaging

Glass wafers find broad use in Micro‑Electro‑Mechanical System (MEMS) packaging. Windows can be formed on glass via screen printing or laser marking to enable anodic bonding with silicon substrates and create hermetic packaging structures. Moreover, glass wafers are utilized for various MEMS devices to provide hermetically‑sealed electrical interconnections.
