ABSTRACT:
A planar silicon head with a structure protected from an overcurrent/overvoltage and a method for fabricating the same. The planar silicon head includes a yoke formed on a silicon substrate, the yoke having a gap for reading and writing data; a hole formed in the silicon substrate, the hole having a conductive layer deposited therein; an internal connector formed at one end of the hole; and a bump formed at the other end of the hole, for forming an electrode including a conductive polymer layer which changes into an insulator with respect to an overcurrent or an overvoltage.
