MULTI-LAYER LTCC SUBSTRATE AND MANUFACTORING METHOD THEREOF

摘要

PURPOSE: A multi-layer LTCC substrate and a manufacturing method thereof are provided to prevent a shot circuit by forming insulating pattern between a conductive VIA and a conductive pattern. CONSTITUTION: A multiple layers LTCC substrate(100) comprises a first dielectric layer(110a), a second dielectric layer(110b), and a third dielectric layer(110c). The first dielectric layer comprises a first conductive pattern(120) and a first conductive VIA(130). The first conductive VIA is connected to the first conductive pattern. The second dielectric layer is laminated in the lower-part of the first dielectric layer. A second dielectric layer comprises a second conductive pattern(140). The second conductive pattern is connected to the first conductive VIA through the first conductive pattern. A third dielectric layer is formed in the lower-part of the second dielectric layer. A third dielectric layer comprises a third conductive pattern(150). The third conductive pattern comprises a insulating pattern(160).
