A semiconductor structure in which the contact resistance in the contact opening is reduced as well as a method of forming the same are provided. This is achieved in the present invention by replacing conventional contact metallurgy, such as tungsten, or a metal silicide, such as Ni silicide or Cu silicide, with a metal germanide-containing contact material. The term “metal germanide-containing” is used in the present application to denote a pure metal germanide (i.e., MGe alloy) or a metal germanide that includes Si (i.e., MSiGe alloy).

A proton exchange membrane (PEM) fuel cell end plate assembly provides an axial direction electric lead on an end plate of the assembly, and minimizes the contact resistance between an end fluid separator plate of a fuel cell stack and a current collector of the assembly. The current collector comprises an electrically conductive flat plate and a solid member connected together. The member goes through an opening on the end plate and provides an axial direction electric lead from the fuel cell stack. Means are provided to firmly contact the current collector and the fluid separator plate to maintain good contact across the entire area between the two components. The means of firmly contacting include moulding or bonding the separator plate and current collector together, or applying pressure to the separator plate and current collector such that firm contact is maintained between the two components.

Methods of forming integrated circuit devices (e.g., memory devices) include the use of preferred self-aligned contact hole fabrication steps. These steps improve process reliability by reducing the likelihood that contact holes will become misaligned to underlying integrated circuit device structures and thereby potentially expose the structures in an adverse manner. Typical methods include the steps of forming a plurality of interconnection patterns on a substrate and then covering a surface of the interconnection patterns and a portion of the substrate with a capping insulating layer such as silicon nitride layer. The capping insulating layer is then covered with an upper interlayer insulating layer different from the capping insulating layer. The upper interlayer insulating layer and the capping insulating layer are then dry-etched in sequence to form a first narrow contact hole that exposes the substrate, but preferably does not expose the interconnection patterns. The first contact hole is then widened in a self-aligned manner using the capping insulating layer as an etch-stop layer. This widening step is performed by wet etching sidewalls of the first contact hole using an etchant that etches the upper interlayer insulating layer faster than the capping insulating layer. In this manner, the first contact hole may be formed to initially compensate for potential misalignment errors and then a self-aligned wet etching step may be performed to widen the first contact hole into a second contact hole so that low resistance contacts (e.g., contact plugs) can be provided therein.

The invention relates to a re-settable, single-phase, thermo/electric circuit breaker utilizing a U-shape bimetallic element of substantial resistance properties in the circuit, so that when a predetermined overload current occurs the bimetallic element self heats and moves to trip a mechanism that opens the breaker circuit. The invention replaces the double-contact break configuration normally associated with a breaker of this type, with a single contact break configuration designed to produce a sliding action between contacts during the normal reset operation, providing a more reliable continuity at the moveable and stationary contact interface that is also less expensive to produce.

The present invention discloses a process for manufacturing a fuel cell and an associated fuel cell array that includes novel pre-shaped current collectors and conforming compression plates. The current collectors are pre-shaped to counteract any deflection of the fuel cell after compression is released during manufacture. The pre-shaped current collectors may bend outwards by the same amount as previously, however, the overall compression relaxation may be much lower because the pre-shaped current collectors are bending back into the flat position, as opposed to away from it. Also provided with the present invention are associated mold plates that induce the desired pre-shaping to the current collectors.
