Inexpensive, lightweight, flexible heating and cooling panels with highly distributed thermoelectric elements are provided. A thermoelectric “string” is described that may be woven or assembled into a variety of insulating panels such as seat cushions, mattresses, pillows, blankets, ceiling tiles, office partitions, under-desk panels, electronic enclosures, building walls, refrigerator walls, and heat conversion panels. The string contains spaced thermoelectric elements which are thermally and electrically connected to lengths of braided, meshed, stranded, foamed, or otherwise expandable and compressible conductor. The elements and a portion of compacted conductor are mounted within the insulating panel. On the outsides of the panel, the conductor is expanded to provide a very large surface area of contact with air or other medium for heat absorption on the cold side and for heat dissipation on the hot side.

An electroplating tool for providing a metal or metal film on a semiconductor wafer during processing thereof has a wafer chucking mechanism with a conductor or conductors associated therewith. The conductor(s) are electrically connected to a controller that applies a voltage or current applied thereto for altering the position of and/or varying the intensity of electromagnetic field lines originating from a source anode of the electroplating tool. The electromagnetic field lines originating from the source anode direct the deposition of metal from the electroplating solution to the semiconductor wafer. The conductor(s) of the wafer chucking mechanism improve and/or modulate the electromagnetic field lines of the electroplating process. This provides greater control of metal deposition during the electroplating process such that uniformity of the metal (e.g. copper) is provided across the semiconductor wafer.

The present invention advantageously provides a method for filling a recess with a slurry that exhibits electrical properties similar to those of the structure which has the recess. The topological surface that includes the recess may be placed adjacent to a pad on which the slurry is disposed. The pad may be rotated to force the slurry into the recess. After the slurry is densely packed into the recess, the slurry may be cleaned from the topological surface exclusive of the recess. The slurry may be heated in order to remove the liquid portion of the slurry. The resulting topological surface is planar since a recess no longer exists therein. The technique hereof may be especially usefull for filling a recess that forms in the surface of a plug or in the surface of a fill dielectric disposed within a trench. Such recesses may form as a result of CMP or etchback.

A preconditioning mechanism for preconditioning a polishing pad is described. The preconditioning mechanism includes an arm capable of being disposed over the polishing pad and a head section located on a distal end of the arm and rotatable about a central axis. Furthermore, the head section includes at least two heads oriented about the central axis and have surfaces for either conditioning or preconditioning the polishing pad, whereby rotation of the head section about the central axis by defined amounts presents at least two heads to the polishing pad so that different of the two heads can engage the polishing pad for conditioning or preconditioning depending upon how far rotation has proceeded.

A method for producing cosmetic samplers that incorporates the genuine cosmetic through the use of bulk thin film application techniques such as extrusion or spray technology. The method comprises first applying a cosmetic slurry to a base substrate and then attaching a cover sheet by means of an adhesive on either wide-web offset or label equipment.
摘要:
A polishing pad having an upper layer with a first visual characteristic. The upper layer is adapted to erode against a pad conditioner at a uniform rate during a pad conditioning process. At least one lower layer with at least a second visual characteristic is disposed beneath the upper layer. The first visual characteristic is visually distinguishable from the second visual characteristic. The at least one lower layer is adapted to polish a substrate, where the visual distinguishability between the upper layer and the at least one lower layer provides a visual indication of whether the pad conditioning process has been accomplished in a uniform manner.

According to one embodiment, a method of forming a low-k dielectric composite film is provided. A low-k interconnect dielectric layer is strengthened by forming whiskers in the low-k film. The whiskers are formed simultaneously with the low-k layer. In one embodiment, the low-k structure is removed by heating a volatile matrix film, leaving a whisker residue.
摘要:
A modification to a chemical mechanical polishing conditioner of a type having a member with a conditioning surface adapted to apply a force to and condition a polishing pad. The conditioner includes at least one sensor disposed within the member, where the at least one sensor is adapted to sense at least one of an amount of the force applied to the polishing pad and a uniformity across the member of the force applied to the polishing pad. In this manner, the force applied by the conditioner to the pad, and the uniformity of the force applied by the conditioner to the pad, can be sensed. These sensed forces can be monitored, reported, and controlled, thus providing a better controlled chemical mechanical polishing process.
