FAQ
Q: What are the main characteristics of an Unlapped Glass Substrate?
A: It typically features high hardness, chemical stability, and dimensional uniformity. However, the surface may have minor roughness or imperfections, which require subsequent lapping or polishing to achieve ultra-flat and smooth surfaces.
Q: What industries use Unlapped Glass Substrates?
A: They are widely used in semiconductor wafer processing, MEMS fabrication, optoelectronics, precision optics, and other high-precision applications where flatness and surface quality are critical.
Q: How should Unlapped Glass Substrates be handled and stored?
A: They should be stored in clean, dry, and dust-free environments, ideally in protective packaging. Handling should avoid direct contact with the surface to prevent scratches or contamination.
Q: How are Unlapped Glass Substrates processed into finished substrates?
A: The substrates undergo lapping, polishing, and sometimes chemical-mechanical planarization (CMP) to achieve required flatness, thickness, and surface roughness for downstream applications.
