Method of fabrication an ultra-thin quartz resonator
First Claim
1. A method for fabricating a resonator comprising:
- receiving a handle substrate;
receiving a quartz substrate comprising a first surface opposite a second surface;
applying an interposer film to the first surface of the quartz substrate;
bonding the handle substrate to the interposer film;
thinning the second surface of the quartz substrate;
forming at least one metallized via in the quartz substrate;
receiving a host substrate;
bonding the quartz substrate to the host substrate; and
removing the handle substrate, thereby releasing the quartz substrate.

Abstract
A method for manufacturing a resonator is presented in the present application. The method includes providing a handle substrate, providing a host substrate, providing a quartz substrate comprising a first surface opposite a second surface, applying interposer film to the first surface of the quartz substrate, bonding the quartz substrate to the handle substrate wherein the interposer film is disposed between the quartz substrate and the handle substrate, thinning the second surface of the quartz substrate, removing a portion of the bonded quartz substrate to expose a portion of the interposer film, bonding the quartz substrate to the host substrate, and removing the handle substrate and the interposer film, thereby releasing the quartz substrate.
