Methods for manufacturing crystal devices |
摘要 |
Crystal devices are disclosed, of which an exemplary device includes a crystal frame comprising a crystal vibrating piece having an electrode pattern and an outer frame supporting the crystal vibrating piece. The device also includes a crystal package base including at least one connection electrode formed on a first main surface and at least one external electrode formed on a second main surface, wherein the second main surface is opposite the first main surface. The crystal frame and crystal base are layered together with a lid wafer to form a 3-layer sandwich. The layers of the sandwich are bonded together by siloxane bonding, which results in the connection electrodes contacting the electrode pattern on the crystal vibrating piece. |
