[Photo Mask Example] Edge finishing process after glass cutting

By applying finishing processes, the taper is removed, improving both appearance and dimensional accuracy!

When requesting a photomask outside of the standard specifications, it is common practice to draw it on a material that is at least one size larger and then cut it down to the desired size. In this case, the scribe cut typically handled in-house involves using a diamond cutter to create a scribe line (a narrow, shallow groove) before breaking it apart, which inevitably results in a taper at the cut edge. Occasionally, this taper is undesirable, and in such cases, we have relied on external vendors with specialized equipment for cutting. This time, to handle it in-house, we introduced a finishing process using a drilling machine to remove the taper. By applying this finishing process, the taper is eliminated, improving both appearance and dimensional accuracy. Additionally, since costs and time previously incurred for outsourcing are reduced, we believe that if the specifications allow for in-house handling, it can provide advantages in terms of cost and delivery time. *For more details, please refer to the PDF document or feel free to contact us.*
