    摘要: A three-dimensional inductor coil is fabricated on top of a semiconductor substrate. The fabrication process includes the steps of depositing a first photoresist layer (406), forming a trench therein, and filling the trench with electroplated metal (404). A second photoresist layer (408) is deposited, and first and second trenches (410) are formed therein and filled with electroplated metal (412). A third photoresist layer (416) is deposited and a trench (418) formed therein, and then filled with electroplated metal (420). The first, second, and third photoresist layers (406, 408, 416) are then removed to expose a multi-loop inductor coil (500, 550).
