  • Patent number: 6376874
    Abstract: An improved capacitor for a semiconductor memory device for preventing a bridge between storage electrodes and enlarging a surface area of a capacitor can be manufactured by forming a second insulating layer on a first insulating layer including a plug, etching the second insulating layer to form a storage electrode opening by using a storage electrode formation mask until the plug and a part of the first insulating layer are exposed, forming a conductive spacer on the sidewalls of the storage electrode opening to connect electrically to the plug, and forming an HSG (hemispherical grain) layer on the surfaces of the conductive spacers and the plug. A capacitor according to the present invention enables the HSG layer to grow on an internal wall of a storage electrode, thereby preventing a micro-bridge between storage electrodes resulting from abnormal growth or over-growth of the HSG layer.

  • Patent number: 6372556
    Abstract: A semiconductor device having a fuse includes a first insulating layer that has a predetermined metal wire, a second insulating layer that has a heat blocking layer being positioned over the predetermined metal wire, and an upper layer. The upper layer includes a deposition structure having a fuse metal layer and a wiring metal layer. The fuse metal layer has a fuse pattern that is used as a fuse and is exposed via a fuse window in the upper layer. The fuse pattern is electrically connected to the wiring metal layer. The semiconductor device is designed so that the heat blocking layer is larger than the fuse window and is positioned under the fuse metal layer. The semiconductor device is further constructed with the fuse metal layer being formed on the metal wire, thereby preventing limitations in the layout arrangement or in the fabrication process in order to achieve a high degree of integration. A method of manufacturing the above semiconductor device is also described.

  • Patent number: 6319824
    Abstract: A method of forming a contact hole for a semiconductor device, and a method of forming a capacitor for a semiconductor device using the same. An interlayer dielectric layer, a contact mask material layer including of a material having a high etching selectivity with respect to the interlayer dielectric layer, an anti-reflection layer, and a photoresist layer, are formed on a semiconductor substrate. A photoresist pattern is formed from the photoresist layer to expose part of the anti-reflection layer, and a flow process is performed on the photoresist pattern to expose even a smaller amount of the anti-reflection layer. The anti-reflection layer and the contact mask material layer are then etched to expose part of the interlayer dielectric layer, and the interlayer dielectric layer is etched to form a contact hole.

  • Patent number: 6310482
    Abstract: A capacitance gauge tracking apparatus used for an exposure system for manufacturing a semiconductor device, a method for tracking a surface of the semiconductor device, a leveling apparatus and a leveling method are provided. The capacitance gauge tracking apparatus includes a ground unit, a probe unit and a gauge unit. The ground unit is connected to a semiconductor substrate. The probe unit is spaced apart from the surface of the semiconductor substrate to be tracked and a constant current of at least two frequency bands is applied to the probe unit. A constant current of a low frequency is applied to the probe unit to thereby perform global leveling by global tracking of the entire surface of the semiconductor substrate and a constant current of a high frequency is applied to the probe unit to thereby perform local leveling by local tracking on the semiconductor substrate.

A photoresist pattern defining the opening can be formed using a photoresist composition that includes either polymer mixture I containing a polymer A in which an acid-labile di-alkyl malonate group is pendant to the polymer backbone, and a polymer B in which a group that thermally decomposes at a temperature lower than the glass transition temperature of the polymer B itself is pendant to the polymer backbone, or polymer mixture II containing the polymer B and a polymer C including a (meth)acrylate as a monomer, as a main component. The size of the opening then can be reduced by thermal flowing the photoresist pattern.
