Title:
METHOD FOR PRODUCING HIGH-FREQUENCY PASSIVE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2020/009145
Kind Code:
A1
Abstract:
This production method is for producing a high-frequency passive component that includes: a substrate comprising a dielectric material; and at least one of a through electrode and a side wall formed on the substrate. In the production method, a prototype having a recess that corresponds to at least one of a side wall and a through electrode is produced from glass, a mold that has a protrusion corresponding to the recess is produced from a metal using the prototype, a substrate comprising a first main surface on which a recess corresponding to the protrusion opens and a second main surface on the opposite side from the first main surface is produced from a resin using the mold, the second main surface of the substrate is polished, part of the recess forms an exposed section that is exposed on the second main surface, and a conductive layer serving as at least one of a side wall and a through electrode is formed on the recess opening on the first main surface of the substrate or on the exposed section exposed on the second main surface of the substrate.
