Questions:
1. How does the method of dry etching the quartz crystal substrate improve the manufacturing process compared to traditional methods?
Answer: The dry etching process allows for precise and controlled removal of material from the substrate, resulting in more accurate and consistent vibrator production.
2. What specific characteristics of the protective film are crucial for ensuring the success of the manufacturing process?
Answer: The protective film must have openings that overlap with specific regions of the substrate to protect them during etching, ensuring the integrity of the vibrator components.
Original Abstract Submitted
a method for manufacturing a vibrator includes a preparation step of preparing a quartz crystal substrate having a first surface and a second surface that are in a front and back relationship, a first protective film formation step of forming a first protective film in an element formation region of the first surface, the first protective film having a first opening overlapping a first groove formation region and a second opening overlapping a second groove formation region, in which a region of the quartz crystal substrate where the vibrator is formed is referred to as the element formation region, a region where the first groove is formed is referred to as the first groove formation region, and a region where the second groove is formed is referred to as the second groove formation region, and a first dry etching step of dry etching the quartz crystal substrate from the first surface through the first protective film. wa<wb, in which wa represents a width of the first opening and wb represents a width of the second opening.
