Abstract:
1. A semiconductor device, comprising: an interlayer insulating film formed on a semiconductor substrate; and an inductor provided on the interlayer insulating film, the inductor comprising: a first soft magnetic thin film pattern formed on the interlayer insulating film, the first soft magnetic film comprising: a) at least one material selected from Co, Ni, an alloy thereof, or an alloy thereof with Fe; b) at least one element selected from Ti, Hf, or B, and c) N; a metal film pattern formed directly on the first soft magnetic thin film pattern; and a second soft magnetic thin film pattern formed directly on the metal film pattern, the second soft magnetic thin film pattern comprising a) at least one material selected from Co, Ni, an alloy thereof, or an alloy thereof with Fe; b) at least one element selected from Ti, Hf, or B; and c) N, wherein: edges of the first soft magnetic thin film pattern, edges of the metal film pattern, and edges of the second soft magnetic thin film pattern are vertically aligned, and the first soft magnetic thin film pattern, the metal film pattern, and the second soft magnetic thin film pattern fully overlap each other.
