Abstract:
A method for forming embedded capacitors on a printed circuit board is disclosed. The capacitor is formed on the printed circuit board by a depositing a first dielectric layer over one or more electrodes situated on the PCB. Another electrode is formed on top of the first dielectric layer and a second dielectric layer is deposited on top of that electrode. A third electrode is formed on top of the second dielectric layer. The two dielectric layers are abrasively delineated in a single step by a method such as sand blasting to define portions of the first and second dielectric layers to create a multilayer capacitive structure.
