A capacitor comprising a polysilicon layer doped with impurities to be conductive, a first dielectric layer formed on the polysilicon layer, a first conductive layer formed on the first dielectric layer, a second dielectric layer formed on the first conductive layer, and a second conductive layer formed on the first dielectric layer. The method preparing an aqueous suspension of germanium dioxide, adding an amino acid and a carboxylic acid to the aqueous suspension of germanium oxide produced, heating the mixture produced with agitation at a temperature of 40-100\xb0 C. The multi-up book is disposed on the label web and held in place by an overlaminate. Since one swap bay device can be set to a master or slave mode, it can be applied to both the portable computers supporting one and two IDE interface channels.
