Abstract: A method of forming a conductive via plug or an interconnect line, or both, of ductile metal within an integrated circuit using mechanical smearing. The process begins with a wafer having a dielectric layer (16), the upper surface of which has been planarized. If both conductive via plugs and interconnect lines are both required within the circuit, a first photomask (17) defines the interconnect lines. A first etch creates channels (18) in the interconnect line locations. A second photomask (19) defines the vias. A second etch creates the vias (20) which pass through the dielectric layer to conductive regions (14) below where contact is to be made. A ductile metal layer (21) is then deposited on top of the dielectric layer (16). The ductile metal layer (21) is then mechanically smeared or deformed in order to force metal from that layer more deeply into the channels (18) and vias (20). The wafer is then slurry polished until all excess metal is removed and the via and channel topography is coplanar with the dielectric layer surface. At this point conductive via plugs (22) and interconnect lines (23) are fully formed.

Abstract: Reaction injection molding apparatus for forming a fiber-reinforced molded article comprises a male die plunger (22) and a female die part (18) relatively movable between open and closed mold positions. The female part has an upwardly opening die cavity, a surface around the cavity for supporting a batt (10) of fibrous reinforcing material overlying the cavity (33) and a shearing edge (17a) defining the periphery of the cavity opening. A clamp (26) operates to clamp peripheral portions of the batt to the supporting surface, whereupon the die plunger is moved into the die cavity to press the overlying portions of the batt thereinto and into a mold formed between the male plunger and sidewalls of the cavity. A cutter (21), also movable into the opening of the die cavity, has a shearing edge that cooperates with the first named shearing edge to shear excess portions of the batt at said periphery from the portions within the cavity and also to seal the mold for the subsequent injection of reactive chemicals into the mold, whereby the batt therein is impregnated with the chemicals to form a fiber-reinforced article upon hardening of the reactive chemicals.

Abstract: In a semiconductor memory device comprising a plurality of groups of memory cell blocks, a plurality of groups of predecoder input signal lines respectively connected to predecoders in the memory cell block groups, and a predecoder input signal generator. The predecoder input signal generator sets the predecoder input signal lines of the selected group to either the high level or the low level in accordance with the external address information. A clamping circuit is provided to clamp substantially half the predecoder input signal lines of the unselected group to the high level, and the remaining half to the low level. Because one half of the predecoder input signal lines of the unselected group is clamped to the high level and the remaining half of the unselected group is clamped to the low level, their line loads serve as decoupling capacitors both at the charging and discharging of the predecoder input signal lines of the selected group, so that the power supply noise is reduced in both occasions.

Abstract: Ionization of air is accomplished by use of a laser beam focussed to a small focal volume (20) of intense electric field adjacent an object to be discharged, e.g. a semiconductor chip or wafer (26). The electric field is sufficiently intense to ionize air. In the manufacture of a semiconductor circuit chip (26), during those steps which are conducted in an air environment, opportunity exists to remove from a surface (28) of a chip, or wafer, charge acquired during the manufacturing process. The ionized air is passed along the chip surface. Ions (24) in the air discharge local regions of the chip surface which have become charged by steps of a manufacturing process. By way of further embodiment of the invention, the ionization may be produced by injection of molecules of water into the air, which molecules are subsequently ionized by a laser beam and directed toward the chip via a light shield with the aid of a magnetic field.
