Abstract
A crystal oscillator and a method for fabricating the same is provided. In the method, a crystal package is provided. The crystal package includes a crystal blank and at least one laser-penetrating area. The laser-penetrating area is exposed outside. The crystal package is provided with at least one airtight space therein. At least one getter is formed in the airtight space. The location of the laser-penetrating area corresponds to that of the getter. A laser beam penetrates through the laser-penetrating area to activate the getter, thereby increasing the degree of vacuum of the airtight space.
