A diamond film formation method includes forming, in a composite of a metal material and a semiconductor material, diamond nuclei on a surface of the metal material at a temperature below 650&#xb0; C. in a first mixed gas containing at least carbon and hydrogen, and growing the diamond nuclei formed in the composite at a temperature below 750&#xb0; C. in a second mixed gas containing at least carbon and hydrogen to form a diamond film.

Diamond film formation method and film formation jig thereof

Disclosed is a dc-to-dc converter comprising a switching transistor, a pulse-width modulation controller, a sandwich-type planar inductor, which accumulates an electromagnetic energy at ON state and releases the accumulated electromagnetic energy at OFF state of the switching transistor, a smoothing capacitor, a rectifying element, and a planar search coil for detecting an overcurrent flowing the planar coil, disposed on one of the outer surfaces of the soft magnetic layers constituting the planar inductor.
