MAGNETIC SHIELDING FOR ELECTRONIC CIRCUITS WHICH INCLUDE MAGNETIC MATERIALS |
摘要 |
Shielded electronic integrated circuit apparatus ( 5 ) includes a substrate ( 10 ), with an eletronic integrated circuit ( 15 ) formed thereon, and a dielectric region ( 12 ) positioned on the electronic integrated circuit. The dielectric region and the substrate are substantially surrounded by lower and upper magnetic material regions ( 26, 30 ), deposited using electrochemical deposition, and magnetic material layers on each side ( 32, 34 ). Each of the lower and upper magnetic material regions preferably include a glue layer ( 36, 40 ), a seed layer ( 28, 24 ), and an electrochemically deposited magnetic material layer ( 26, 30 ). Generally, the electrochemically deposited magnetic material layer can be conveniently deposited by electroplating. |
