  • Patent number: 6514591
    Abstract: An optical information recording medium comprises a substrate and a multilayered film formed on the substrate, the multilayered film comprising a first information layer, a separating layer, and a second information layer in this order from the side of the substrate. Each of the first information layer and the second information layer comprises a recording layer in which an optical change is caused by irradiation of laser light, and in the first and second information layers, signals can be recorded/reproduced on/from the recording layer by irradiating the recording layer with laser light through the substrate. The first information layer comprises a first protective layer, the recording layer, and a second protective layer in this order from the side of the substrate, and at least one of the first protective layer and the second protective layer comprises at least two layers. The at least two layers comprise a first layer and a second layer in this order from the side near the recording layer.

  • Patent number: 6063660
    Abstract: A fabricating method and a structure of a stacked-type capacitor is provided comprising forming a first dielectric layer having a first via on a semiconductor substrate. A first conductive layer is filled into the first via. Then, insulating layers and dielectric layers are formed. A photolithography step is used to form a second dendriform via in the insulating layers and the dielectric layers. A second conductive layer is filled in the second dendriform via. The insulating layers and conductive layers are removed to form a dendriform lower electrode. The dendriform electrode provides a larger surface area to increase capacitance. Further, a polysilicon layer of hemispherical grains is formed to increase the surface area of the lower electrode.
