Etching: Technology to process materials using the corrosive action of chemicals and other agents.

Combined with photolithography technology, it is possible to form a large number of tuning-fork or AT quartz crystal blanks in a batch from a quartz crystal blank, which are small and have good dimensional accuracy.
It is also used to adjust the thickness of AT crystal blanks to adjust their frequency.

The miniaturization of quartz crystal units is progressing along with the miniaturization of electronic devices, and this is an essential elemental technology for realizing compact, high-precision processing that is difficult to achieve with machining.
