Abstract:
A vibrator device includes a semiconductor substrate, a vibrator unit, a cover, and an insulating film. The vibrator unit is disposed at a first surface of the semiconductor substrate, and includes a vibrator element, and an excitation electrode disposed at the vibrator element and having a portion facing the semiconductor substrate. The cover is bonded to the first surface in a joint portion surrounding the vibrator unit. The insulating film is disposed at the first surface. The insulating film overlaps the portion of the excitation electrode in plan view, and is absent at the joint portion of the semiconductor substrate and the cover.
