After a hole is formed in a polishing pad, a transparent window plate is inserted into the hole. Here, a gap is left between the upper surface of the transparent window plate and the outermost surface constituting the working surface of the polishing pad. During polishing, the polishing head holding the wafer applies a load to the polishing pad by means of a load-applying mechanism, so that the polishing pad and transparent window plate are compressed. In this case, the system is arranged so that the gap remains constant, and so that a dimension equal to or greater than a standard value is maintained. Since the upper surface of the transparent window plate is recessed from the upper surface of the polishing pad, there is no scratching of the surface of the transparent window plate during dressing. Accordingly, the polishing pad has a long useful life.

The present invention provides a permanent protective hardmask which protects the dielectric properties of a main dielectric layer having a desirably low dielectric constant in a semiconductor device from undesirable increases in the dielectric constant, undesirable increases in current leakage, and low device yield from surface scratching during subsequent processing steps. The protective hardmask further includes a single layer or dual layer sacrificial hardmask particularly useful when interconnect structures such as via openings and / or lines are formed in the low dielectric material during the course of making the final product. The sacrificial hardmask layers and the permanent hardmask layer may be formed in a single step from a same precursor wherein process conditions are altered to provide films of differing dielectric constants. Most preferably, a dual damascene structure has a tri-layer hardmask comprising silicon carbide BLoK(TM), PECVD silicon nitride, and PECVD silicon dioxide, respectively, formed over a bulk low dielectric constant interlevel dielectric prior to forming the interconnect structures in the interlevel dielectric.

A metal card or a hybrid metal-plastic includes an acrylic resin protective clear coat layer and / or a “hard” nano-particle top-coat layer overlying any exposed metal surface in order to insulate the metal and reduce the likelihood of an electrostatic discharge (ESD) or a short circuit condition. In a particular embodiment the “hard” nano-particle top-coat layer overlies the clear coat layer. The dual stage protective layers which include a clear-coat layer and a top-coat ensure that the problem associated with an ESD and / or a short circuit condition is minimized. In addition, the dual stage protection imparted to a card by forming a clear-coat layer and a top-coat layer ensures that any card surface treatment or card decoration is protected over time from excessive wear or scratching due to use in conjunction with a POS device and / or handling.

A tool-carrying assembly to be secured by a waist-encircling belt, and, additionally, by straps encircling the legs of a workman using the belt assembly. The assembly is thus stabilized, and enhanced weight distribution is achieved. Elements of the belt assembly include a waist-encircling band supporting a pair of laterally spaced, depending panels each carrying tool-accepting pockets. The pockets preferably carry visual markings and coding as well as other indicia identifying clearly the specific tools to be "housed" or carried in and to be returned to each pocket after use. Inventory control of the tools is thereby significantly enhanced. Pivotal flaps depending from the band-carried panels serve to cover the tools when not in use, and to prevent the tools from scratching or otherwise marring any article, or fixture, or "workpiece" requiring the workman's attention. The panels and the tools carried thereby are disposed in lateral, spaced zones at the wearer's sides (and not directly in the front of one's body) thus further to reduce any likelihood of the tools coming into damaging physical contact with an article being worked upon. That is, both frontal and rearwardly located zones about the wearer of the tool belt assembly are rendered essentially free and clear of all tools and other mechanical impediments. While wearing the tool assembly of the invention, a worker can, without any discomfort, lie upon and use a "creeper". Significantly, a frontal sector of the belt itself is covered with a relatively soft, non-marring protective pad, composition, or surface material effective to prevent possible damage from a workman's belt buckle. An additional feature of the invention is that the panels may be structured to constitute a core sandwiched between a pair of encasing sheet-like webs. The resulting composite is readily formable to provide selectable visual patterns, designs or indicia, for example, to identify product name or sources and / or to constitute decorations.
