Petterning: Our glass masks have a good reputation in the field of marking on semiconductor packages with YAG laser.

* Outline
Si anisotropic etching is a technique which makes half holes and through holes using the direction of the Si crystal.
For instance, by using anisotropic etching of the Si wafer (1.0.0) type, very precise patterns are made along the crystal direction of 54.7'.
Glass etching is applied in various fields since it is flexible in its selection of materials, work size, etc. though unlike the Si wafer, it has no direction.
