Abstract:
1. A method of manufacturing a capacitor-embedded low temperature co-fired ceramic substrate, the method comprising: manufacturing a capacitor part by firing a deposition including at least one high dielectric ceramic sheet to form a capacitor part; providing a plurality of low temperature co-fired green sheets each having at least one of a conductive pattern and a conductive via hole thereon; forming a low temperature co-fired ceramic deposition by depositing the low temperature co-fired green sheets to embed the capacitor part in the low temperature co-fired ceramic deposition, the embedded capacitor part connected to the one of conductive pattern and conductive via hole of an adjacent one of the green sheets; and firing the low temperature co-fired ceramic deposition having the capacitor part embedded therein, wherein the capacitor part comprises at least one deposited capacitor block including a plurality of dielectric layers and first and second internal electrodes formed on top and bottom surfaces of the dielectric layers, respectively, and the forming the low temperature co-fired ceramic deposition comprises: punching some of the low temperature co-fired green sheets to form at least one cavity inside the low temperature co-fired ceramic deposition; depositing the low temperature co-fired green sheets; and mounting the deposited capacitor block on the cavity in the depositing process, and wherein the cavity has a depth greater than a depth of the deposited capacitor block mounted thereon, considering a contraction degree of the low temperature co-fired green sheets during the firing.
