Abstract:
1. A method for fabricating a magnetic device using semiconductor technology comprising the steps of: forming a first conductor over a substrate; patterning a first photoresist layer disposed over the first conductor to form via holes that expose a portion of the first conductor; forming first partial via structures within the via holes that are connected to the first conducton; forming a second photoresist layer disposed over the first conductor and the first partial via structures and using the second photoresist layer to form a magnetic core arrangement disposed over the first conductor; patterning a third photoresist layer disposed over the magnetic core arrangement and the second photoresist layer to form via holes co-linear with the first partial via structures; forming second partial via structures within the co-linear via holes that are connected to the first partial via structures; and forming a second conductor over the magnetic core arrangement connected to the second partial via structures, thereby forming via structures adapted to electrically connect the first conductor to the second conductor.
