摘要:
A semiconductor integrated circuit package, a printed circuit board, a semiconductor apparatus, and a power supply wiring structure that allow attainment of stable power source and ground wiring without causing resonance even in a high-frequency bandwidth are provided. In an interior portion of the package, a power source wiring and a ground wiring constitute a pair wiring structure in which the power source wiring and the ground wiring are juxtaposed at a predetermined interval so as to establish electromagnetic coupling therebetween. A plurality of pair wiring structures are combined in such a manner that, when viewed in a section perpendicular to a wiring extending direction, the pair wiring assembly assumes a staggered (checkered) configuration. It is preferable that, each of the silicon chip and the printed circuit board, like the package, has pair wiring structures disposed inside.

To achieve higher packaging density and one wafer level for a full-sized wafer memory, or wafer-scale integration memory system, the wafers are vertically stacked with each other at a predetermined interval. A packaging technique is improved in such a way that a memory system layout can be precisely realized and a precise through hole can be formed. Moreover, other chips are fixed on the wafer so as to achieve furthermore the high packaging density.

摘要:
In a process for producing an alcohol by hydroformylation comprises reacting a straight chained, branched or alicyclic mono-olefin having from 3 to 20 carbon atoms with carbon monoxide and hydrogen to form an alcohol having carbon atoms greater in number by one than the carbon atoms of the mono-olefin, the improvement comprises(a) a fist step in which the mono-olefin is hydroformylated with use of a cobalt catalyst in the presence of a gas mixture of carbon monoxide and hydrogen at a high temperature under high pressure to selectively form an aldehyde at a conversion of the mono-olefin being from 50 to 95 mol % while suppressing the formation of an alcohol, and the cobalt catalyst is then removed from the unreacted olefin and the formed aldehyde by decomposition or extraction, and(b) a second step in which the mixture of the unreacted mono-olefin and the formed aldehyde freed from the cobalt catalyst in the first step is reacted with a gas mixture of carbon monoxide and hydrogen with use of a cobalt organophophine complex catalyst at a high temperature under high pressure thereby simultaneously hydroformylating the unreacted mono-olefin and hydrogenating the aldehyde to form the alcohol.
