Abstract
A method for fabricating a multilayer ceramic substrate having a cavity with multi-steps therein for mounting an electronic component is provided. A block is inserted into a lower cavity segment of the cavity formed in a green sheet laminate to be the multilayer ceramic substrate, wherein the block has substantially the same three-dimensional shape as that of the cavity segment and has a height equal to or larger than the depth of the cavity segment. Thus, the pressing step is performed in a state such that the cavity has an apparent single step.
