Multilayer ceramic substrate utilizing an intaglio plate with a plurality of grooves having different depths

摘要

A multilayer ceramic substrate has a first conductive pattern that is transfer-printed on a ceramic substrate using an intaglio plate made of a flexible resin. The intaglio plate has a plurality of grooves with different depts. A first insulation layer is on the first conductive pattern, and a second conductive pattern is on the insulating layer. The two conductive patterns are coupled by a via.
