InactiveUS20080157157A1High operation speedLow power consumptionTransistorSolid-state devicesPhysicsSulfur dioxide
A DRAM capacitor uses ruthenium or ruthenium oxide as an upper electrode and hafnium dioxide or zirconium oxide as an insulation layer. The DRAM capacitor is intended to suppress diffusion of ruthenium, etc. into hafnium dioxide. Tantalum pentoxide or niobium oxide having a higher permittivity than that of the insulation layer is inserted as a cap insulation layer to the boundary between the upper electrode of ruthenium or ruthenium oxide and the insulation layer of hafnium dioxide or zirconium oxide to thereby suppress diffusion of ruthenium, etc. into hafnium dioxide, etc.

The present invention provides an improved process for the preparation of MgO of high purity >99% from salt bitterns via intermediate formation of Mg(OH)2 obtained from the reaction of MgCl2 and lime, albeit indirectly, i.e., MgCl2 is first reacted with NH3 in aqueous medium and the slurry is then filtered with ease. The resultant NH4Cl-containing filtrate is then treated with any lime, to regenerate NH3 while the lime itself gets transformed into CaCl2 that is used for desulphatation of bittern so as to recover carnallite and thereafter MgCl2 of desired quality required in the present invention. The crude Mg(OH)2 is dried and calcined directly to produce pure MgO, taking advantage of the fact that adhering impurities in the Mg(OH)2 either volatilize away or get transformed into the desired product, i.e., MgO.
