摘要:
A semiconductor manufacturing method comprises forming a leveling guard ring defining an interior area into which are fabricated one or more devices. In certain embodiments two or more matched devices, such as in a common centroid layout, are fabricated in the interior area. The guard ring is formed on at least one particular layer for a particular processing step. By the guard ring overwhelming the effect of local features' elevation differences, photoresist thereafter applied consequently has a more uniform height across the interior area, resulting in more uniform devices. In some embodiments, a plurality of guard rings enclosing respective arrays of matched devices are arranged over the surface of a semiconductor wafer, spaced apart so as to be not local to one another. Based on the equalizing effect by each of the guard rings, the respective devices arranged in the interior areas are more evenly matched to equivalent devices in far-spaced guard rings. Thus, both local and global matching are achieved.

In a method of producing isotopes in a light water power reactor, one or more targets within the reactor may be irradiated under a neutron flux to produce one or more isotopes. The targets may be assembled into one or more fuel bundles that are to be loaded in a core of the reactor at a given outage. Power operations in the reactor irradiate the fuel bundles so as to generate desired isotopes, such as one or more radioisotopes at a desired specific activity or stable isotopes at a desired concentration.

摘要:
A resistor formed on a material layer of a semiconductor integrated circuit and a method for forming the resistor. The resistor comprises a region of resistive material with a plurality of conductive contacts or plugs in electrical contact with and extending away from the resistive material. A first and a second interconnect line are formed overlying the plugs and in conductive contact with one or more of the plurality of plugs, such that a portion of the resistive material between the first and the second interconnect lines provides a desired resistance. According to a method of the present invention, the plurality of conductive contacts are formed using a first photolithographic mask and the first and the second interconnect lines are formed using a second photolithographic mask. The desired resistance is changed by modifying the first or the second mask such that one or more dimensions of a region of the resistive material between the first and the second interconnect lines is altered.
摘要:
A thermally conductive structure for a semiconductor integrated circuit and a method for making the structure. The structure comprises one or more vertical and/or horizontal thermally conductive elements disposed proximate a device for improving thermal conductivity from the device to a substrate of the integrated circuit. In one embodiment a heat sink is affixed to the integrated circuit for heat flow from the integrated circuit. The method comprises forming openings in material layers overlying the semiconductor substrate, wherein the openings are disposed proximate the device and extend to the substrate. A thermally conductive material is formed in the openings to provide a thermal path from the device to the substrate.

The present invention relates to a presentation folder that may be provided in a unique arrangement such as with a shipping package configuration thereby eliminating the need to provide a separate envelope and business communication piece. The construction is created from a relatively planar paperboard material that can be handled efficiently by courier or delivery companies in a folded or assembled state and which includes at least one and preferably two pockets that are adhered to separate faces of the paperboard blank. The assembly may include other arrangements such as a pocket on one face and a removable printed advertising piece on the other face. The pocketed faces of the paperboard blank are brought into contact with one another and through use of a closure portion, which may include foldable flaps or adhesive coated tabs, the closure portion is used to seal the construction into a parcel delivery configuration.

The present invention is directed to a continuous system for creating high quality pressure sensitive products that can be provided in both a linered and liner free arrangement. The process provides the ability to variably image individual portions of a sheet that is then cut into separate segments which form the intermediate label portions. A release material is applied over one surface of the segment and directly over the printed areas and a pattern of pressure sensitive adhesive is applied to a second surface opposite that of the first surface. The label segments may be die cut and are then may be placed on a temporary carrier web or alternatively can be positioned in a slightly overlapping arrangement to create a temporary web to transport the label segments to a collection or use location.

The invention is directed to a combination of a conditioner bath and a calcium modified zinc phosphating solution optionally containing hydroxylamine which provide an improved phosphate coating on the surface of ferrous metal articles. In a preferred embodiment, the treatment process further comprises coating the workpiece with a second lubricant. The three treatments work together to provide finer grained phosphate coatings, longer life of the second lubricant bath and improved adherence of the second lubricant, as compared to a similar phosphating bath that is used alone or with a similar second lubricant.
