Abstract
The present invention provides a multi-layered ceramic substrate including a first insulating sheet having a first via contact; and a second insulating sheet joined to the first insulating sheet, wherein the second insulating sheet has a second via contact aligned with the first via contact up and down to be joined to the first via contact, wherein the first via contact has a form extended to the inside of the second via contact.
Claims23
A multi-layered ceramic substrate, comprising:
- a first insulating sheet having a first via contact;
- and
- a second insulating sheet joined to the first insulating sheet, wherein the second insulating sheet has a second via contact aligned with the first via contact up and down to be joined to the first via contact,
- wherein the first via contact has a form extended to the inside of the second via contact.
A multi-layered ceramic substrate, comprising:
- a first insulating sheet having a first via contact;
- and
- a second insulating sheet joined to the first insulating sheet, wherein the second insulating sheet has a second via contact aligned with the first via contact up and down to be joined to the first via contact,
- wherein the first via contact and the second via contact are formed with conductive pastes having a different contraction ratio.
A manufacturing method of a multi-layered ceramic substrate, comprising:
- preparing a first insulating sheet having a first via contact formed with a first conductive paste;
- preparing a second insulating sheet having a second via contact formed with a second conductive paste which has a different contraction ratio at the timing of sintering in comparison with the first conductive paste;
- arranging the first insulating sheet and the second insulating sheet for the first via contact and the second via contact to be aligned up and down;
- and
- sintering the first insulating sheet and the second insulating sheet.
