| Zusammenfassung: | PURPOSE:To make the control of static capacitance easy, by forming a conductive film between an adhesive coated on a stem and a substrate. CONSTITUTION:In bonding and fixing a substrate 3 to a specified positin of the surface of a stem 1, a conductor film 4 consisting of silver paste etc. is formed between an adhesive 2 coated on the stem 1 and the subsrate 3. The static capacitance as a surface acoustic wave device can be controlled by varying the shape of the conductor film 4. |
