Patent ID: 8216860

Claim:
A method of fabricating a semiconductor device, comprising: forming an interlayer insulating film on a semiconductor substrate; depositing a first soft magnetic thin film on the interlayer insulating film through sputtering using a target comprising at least one of Fe, Co, Ni, or alloys thereof, the target further comprising at least one of Ti, Hf, or B, the sputtering being performed using N 2 reactive gas; forming a metal film on the first soft magnetic thin film; depositing a second soft magnetic thin film on the metal film through sputtering using the same or another target comprising at least one of Fe, Co, Ni, or alloys thereof, the target further comprising at least one of Ti, Hf, or B, the sputtering being performed using N 2 reactive gas; and patterning the first soft magnetic thin film, the metal film, and the second soft magnetic thin film, which are laminated, using a same mask, to form an inductor.
