MANUFACTURING METHOD OF MULTI-LAYER SUBSTRATE

摘要

A method for manufacturing a multilayer ceramic substrate is provided to improve fixing intensity between a ceramic lamination and an external electrode in a second baking process by preventing crystallization of a glass component included in the ceramic lamination in a first baking process. A ceramic lamination manufacturing process is performed to manufacture a ceramic lamination including a glass component. A constraining layer is laminated on an upper part and a lower part of the ceramic lamination. A first baking process is performed within a first temperature range to prevent the crystallization of the glass component included in the ceramic lamination. The constraining layer is removed after the first baking process. An external electrode is formed on the ceramic lamination. A second baking process is performed to bake the ceramic lamination including the external electrode in a second temperature range. The second temperature range is higher than the first temperature range.
