The present invention provides a horizontal linear vibrator which can reduce the thickness but increase the strength of vibrations while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The casing defines an internal space therein. A first magnet is attached to an upper plate of the casing. The bracket is coupled to the lower end of the casing. The second magnet is attached to the bracket such that different poles of the first and second magnets face each other. The vibration unit has a weight, and a cylindrical coil which is provided in or under the weight. The springs are coupled to the sidewall plates of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.

A method of fabricating a T-gate is provided. The method includes the steps of: forming a photoresist layer on a substrate; patterning the photoresist layer formed on the substrate and forming a first opening; forming a first insulating layer on the photoresist layer and the substrate; removing the first insulating layer and forming a second opening to expose the substrate; forming a second insulating layer on the first insulating layer; removing the second insulating layer and forming a third opening to expose the substrate; forming a metal layer on the second insulating layer on which the photoresist layer and the third opening are formed; and removing the metal layer formed on the photoresist layer. Accordingly, a uniform and elaborate opening defining the length of a gate may be formed by deposition of the insulating layer and a blanket dry etching process, and thus a more elaborate micro T-gate electrode may be fabricated.
