Method for manufacturing printed circuit board with thin film capacitor embedded therein
摘要:
In a method for manufacturing a printed circuit board with a thin film capacitor embedded therein, a conductive metal is sputtered via a first mask to form a lower electrode. A dielectric material is sputtered via a second mask to form a dielectric layer. The conductive metal is sputtered via a third mask to form an upper electrode. An insulating layer is stacked on a stack body with the upper electrode formed therein and via holes are perforated from a top surface of the insulating layer to a top surface of the lower electrode and from the top surface of the insulating layer to a top surface of the upper electrode formed on the substrate. Also, the stack body with the via holes formed therein is electrolytically and electrolessly plated.
