    摘要: A semiconductor memory device includes a channel region, a gate electrode adjacent the channel region, and a charge-trapping layer between the channel region and the gate electrode. A voltage is applied between the gate electrode and the channel region to cause a first current of a first kind of charge carriers from the channel region to move into the charge-trapping layer and to cause a second current of a second kind of charge carriers from the gate electrode to move into the charge-trapping layer, until the value of the second current is at least half the amount of the first current value.

A charge-trapping layer and a conductive layer are deposited on the surface of the semiconductor wafer. Using a mask layer on top of the conductive layer, contact holes are formed wherein an insulating layer is formed. An etch stop layer is deposited on the surface of the semiconductor wafer. Above the etch stop layer, a dielectric layer is deposited and is patterned so as to form contact holes. Subsequently, the contact holes are enlarged through the etch stop layer and the insulating layer to the buried bit lines.

    摘要: A three-dimensional, one transistor cell arrangement for dynamic semiconductor memories utilizing a trench capacitor in the substrate, and provided with a switching field effect transistor including an insulated gate electrode connected to the source/drain zone, the bit line contact for the connection of the switching transistor being arranged to be self-adjusted on the drain region in the semiconductor substrate, and overlapping the gate electrode with insulating layers on all sides. It also overlaps the neighboring field oxide region. The insulation layer laying beneath the bit line and over the gate level is a triple layer composed of silicon oxide/silicon nitride/silicon oxide, and in the through hole etching which is carried out by specific etching steps, there exists a self-adjusted overlapping contact. By eliminating the imprecision caused by the lithography, the space requirement of a memory cell can be reduced by about 20%. The invention is particularly utilized in the manufacture of 4 megabit DRAMs.

    摘要: In a roll having a hollow roll through which a stationary cross piece extends, a bearing housing is provided for a bearing which engages an axial extension of the hollow roll. The extension has a smaller outer diameter than the outer diameter of the hollow roll. The bearing is located in the bearing housing between the outside circumference of the extension and the inside circumference of the bearing housing. The bearing housing has lubricant feed and discharge passages separate from means for hydraulically supporting the hollow roll. The bearing housing has a bore which fits over the end of the cross piece without play thereby forming a support distance.
