  • Publication number: 20040118840
    Abstract: The invention relates to a device (1) for producing high frequency microwaves comprising a cathode arrangement with heatable cathodes (15) for emitting electrons, two grid arrangements for controlling and focusing fluxes of electrons and an anode (3) for receiving the electrons flowing through the grid arrangements. The cathode arrangement and the first grid arrangement, in addition to a locking element or a throttle element (16), define an input cavity (12) forming a resonant cavity. The anode (3) and the second grid arrangement define an output cavity also forming a resonant cavity. Said cathode arrangement comprises a mounting for the cathode (15) such that a deformation of the cathode (15) is avoided by reducing the distance between the heatable cathode and the grids (18).

  • Publication number: 20040082162
    Abstract: The present invention is related to a method for fabricating a semiconductor device capable of preventing occurrences of void and seam phenomena caused by a negative slope of an insulation layer or a bowing profile phenomenon in a cross-sectioned etch profile of a contact hole. To achieve this effect, the attack barrier layer or the capping layer is additionally deposited on the profile containing self-aligned contact holes in order to prevent an undercut of the inter-layer insulation layer, which is a main cause of the seam generations. Also, the attack barrier layer has a function of preventing the inter-layer insulation layer from being attacked during the wet cleaning/etching process. Ultimately, it is possible to improve device characteristics with the prevention of the seam generations.

  • Patent number: 6703314
    Abstract: Provided is a method for forming a self aligned contact (SAC) of a semiconductor device that can minimize the loss of gate electrodes and hard mask. The method includes the steps of: providing a semiconductor substrate on which a plurality of conductive patterns are formed; forming a first insulation layer along the profile of the conductive patterns on the substrate; forming a second insulation layer on the substrate and simultaneously forming voids between the conductive patterns; forming a third insulation layer on the first insulation layer; and forming contact holes that expose the surface of the substrate between the conductive patterns by etching the third insulation layer and the second insulation layer covering the voids.

  • Publication number: 20040009656
    Abstract: A method for fabricating a semiconductor device includes forming a plurality of first plugs contacted to a substrate by passing through a first inter-layer insulation layer; forming a second inter-layer insulation layer on the first plugs; forming a conductive pattern contacted to a group of the first plugs by etching selectively the second inter-layer insulation layer; and forming a contact hole exposing a surface of the first plug that is not contacted to the conductive pattern by etching selectively the second insulation layer with use of a dry-type and wet-type etch process, wherein an attack barrier layer is formed on between the first inter-layer insulation layer and the second inter-layer insulation layer to thereby prevent an incidence of attack to the first interlayer insulation layer contacted to the first plug during the wet-type etch process for forming the contact hole.

  • Publication number: 20030124465
    Abstract: The present invention relates to a method for fabricating a semiconductor device capable of improving an overlap margin that occurs when forming a conductive pattern, such as a bit line or a bit line contact. In order to achieve this effect, the method for fabricating a semiconductor device includes the steps of: forming a plug passing through an insulation layer to be contacted with a substrate board; forming a planarization insulation layer on an entire surface including the plug so as to cover defects appeared at a surface of the plug; forming a protective insulation layer on the planarization insulation layer for preventing losses of the planarization insulation layer resulted from a subsequent cleaning process; performing a process with an etchant; and forming a conductive layer contacted to the plug by passing through the protective insulation layer and the planarization insulation layer.
