    摘要: A fluxgate sensor is integrated in a printed circuit board. The fluxgate sensor has two bar-type (or rectangular-ring shaped) soft magnetic cores to form a closed magnetic path on a printed circuit board and an excitation coil in the form of a metal film is wound around the two bar-type soft magnetic cores either in a united structure that winds the two bar-type soft magnetic cores altogether, or in a separated structure that winds the two bar-type soft magnetic cores respectively, both in a pattern of number ‘8’. A pick-up coil is mounted on the excitation coil, either winding the two bars altogether, or respectively, in a solenoid pattern. The fluxgate sensor integrated in the printed circuit board can be mass-produced at a cheap manufacturing cost. The fluxgate sensor also can be made compact-sized, and at the same time, is capable of forming a closed-magnetic path. As a result, flux leakage is minimized, and the fluxgate sensor has a high sensitivity as it detects the magnetic field through a variable driving.

    摘要: A method for manufacturing a metal structure using a trench includes etching a semiconductor substrate to form a trench, depositing a seed layer over the semiconductor substrate including in the trench, stacking an insulating layer over the seed layer, removing a portion of the insulating layer to expose a portion of the seed layer at a bottom of the trench, filling the trench with a metal material, and removing the seed layer and the insulating layer on the semiconductor substrate. As a result, a subsequent process in forming a multi-layered structure may be easily carried out, thereby simplifying a manufacturing process.

    摘要: Disclosed is a magnetic field sensor of high sensitivity, and which is power-saving and can be manufactured with low cost in a very small size. The magnetic field sensor includes a soft magnetic core formed to construct a closed-magnetic circuit on a semiconductor substrate, a magnetic field sensing coil formed by a metal film in a shape that winds the soft magnetic core, and a drive line for exciting the soft magnetic core by directly applying an electric current thereto. The drive line is formed in a rectangular angle to the magnetic field sensing coil, and connected to the both ends of the soft magnetic core in a length direction.
