Abstract: PURPOSE: A field emission display device adopting a triple junction electron discharge mechanism is provided to simplify a fabrication method by eliminating an etching process. CONSTITUTION: A field emission display device consists of an emitter film(52), a gate film(50), a cathode(54), and an anode(60). The gate film served to provide an electric field to the emitter film for facilitating discharge of an electron. The cathode(54) which is patterned on the emitter film served to provide the electron to the emitter film. The electron inflows into the emitter film when a voltage is applied between the gate film and the cathode. At this time, since an energy level of the triple junction area in which the cathode and the emitter film contact with a vacuum area lowers than an energy level of an area in which the emitter film directly contact with a vacuum area, the electron is discharged via a triple junction area(58). Therefore, it is possible to eliminate an etching process of the emitter film.

Abstract: PURPOSE: A method for forming a plug of a semiconductor device is provided to improve the planarity of metallization layers on the plug by eliminating an undesirable key hole in the plug. CONSTITUTION: An interlayer dielectric(22) is formed on a semiconductor substrate(20) having an impurity region(21) therein, and then patterned to make a contact hole exposing the impurity region(21). Next, the top of the interlayer dielectric(22) and an inner wall of the contact hole are coated with a diffusion barrier(23). A plug layer(24) is then formed on the diffusion barrier(23) by the deposition of tungsten. At this time, if a void(V2) exists in the plug layer(24) within the contact hole, a key hole appears undesirably on the plug layer(24) due to the void(V2). To remove the key hole, a supplementary planarizing layer is coated on the plug layer(24) and then leaves a supplementary planarizing part(250) in the key hole by an etchback process. The plug layer(24) is subjected to the following etchback process. Therefore, the plug layer(24) is removed together with the supplementary planarizing part(250) except a planar plug(240) in the contact hole.
