The protrusion projects toward the vibrating portion and has first and/or second sloped surfaces. First and second extraction electrodes extend from respective excitation electrodes via respective joining portions to respective external electrodes. The extraction electrodes pass across the first plane surface and first sloped surface or across the second plane surface and second slanted surface.

摘要： Piezoelectric vibrating devices have piezoelectric vibrating pieces of which the vibration frequency is measurable individually on a wafer scale, without being affected by adjacent piezoelectric devices on the wafer. An exemplary piezoelectric device includes a piezoelectric vibrating piece having excitation electrodes and respective extraction electrodes. The device includes a package base with two connecting electrodes facing the vibrating piece and connected to respective extraction electrodes. Two pairs of mounting terminals are situated on the outer surface of the package base. Also on the outer surface of the package base are two pairs of opposing castellations that are recessed toward the center of the package base. Edge-surface electrodes connect the first and second main surfaces of the base; one pair is connected to the connecting electrodes and the other pair is connected to respective mounting terminals.

摘要： Methods are disclosed for manufacturing quartz-crystal devices. In an exemplary method three wafers are prepared. One is a quartz-crystal wafer defining multiple quartz-crystal pieces; a second is a wafer defining multiple package bases; and a third is a wafer defining multiple lids for the package bases. Each quartz-crystal piece has a respective excitation portion that vibrates when electrically energized and a respective frame portion surrounding the excitation portion. The quartz-crystal wafer has main surfaces that are lapped and polished to mirror-finish them. The base wafer defines multiple package bases each having a floor surface, a bonding surface surrounding the floor surface, and a lower main surface. The lid wafer defines multiple lids each having a ceiling surface, a bonding surface surrounding the ceiling surface, and a upper main surface. The quartz-crystal wafer is sandwiched between the base and lid wafers. The wafers are bonded together by bonding respective main surfaces of the frame portion to respective bonding surfaces. At least two of the upper main surface, lower main surface, floor surface, and ceiling surface are rougher than the surfaces of the excitation portion.
