Beschreibung
Zusammenfassung:	A three-dimensional circuit board, including a ceramic substrate and multiple circuits, is provided. The ceramic substrate has a first plane, a second plane, a third plane located between the first plane and the second plane, a first side surface connecting the first plane and the second plane, and a second side surface connecting the first plane and the third plane and opposite to the first side surface. A first height of the first side surface is greater than a second height of the second side surface. The circuits are separately embedded on the first plane of the ceramic substrate and extend along the first side surface to be embedded on the second plane.
