A method and structure for a programmable circuit that includes a magnetic device having a reluctance which is alterable. The magnetic device can be programmed into one of three magnetic field orentations or states. Conventional VLSI fabrication steps are used for compatability with low-k dielectric Back-End-Of-Line (BEOL) processing.

An article including a microelectronic substrate is provided as an article usable during the processing of the microelectronic substrate. Such article includes a microelectronic substrate having a front surface, a rear surface opposite the front surface and a peripheral edge at boundaries of the front and rear surfaces. The front surface is a major surface of the article. A removable annular edge extension element having a front surface, a rear surface and an inner edge extending between the front and rear surfaces has the inner edge joined to the peripheral edge of the microelectronic substrate. In such way, a continuous surface is formed which includes the front surface of the edge extension element and the front surface of the microelectronic substrate, the continuous surface being substantially co-planar and flat where the peripheral edge is joined to the inner edge.

An X-ray mask pellicle is capable of protecting the X-ray mask from contaminants and the wafer from contact with the X-ray absorber material of the mask. The X-ray mask pellicle is sufficiently thin to allow X-ray exposure at the required mask to wafer gaps yet is sufficiently durable, replaceable, tough and X-ray resistant to be used in X-ray lithography. A thin (organic or inorganic) X-ray mask pellicle to be placed covering the X-ray mask pattern area is fabricated as a thin film and attached to a support ring. A selected area of the pellicle film, tailored to cover the absorber pattern in the X-ray mask, is etched to decrease its thickness to below 2 .mu.m. If the thin film of the pellicle is not itself conductive, a thin conductive film may be coated on both sides. In an alternative embodiment, the separation between the pellicle and the X-ray mask can be achieved by forming the mask with a stepped profile.

A structure and method for removing and recovering an anodically bonded glass device from a substrate using a metal interlayer interposed between the glass and the substrate is provided. As used in semiconductor mask fabrication, the structure comprises a silicon wafer substrate coated with a membrane on which a metal interlayer is disposed. The metal interlayer and a glass device are anodically bonded together. Recovery of the glass device is accomplished by chemically and mechanically removing the wafer and its membrane from the metal interlayer. The membrane is preferably removed using reactive ion etching to which the metal interlayer is resistant. The metal interlayer is then removed from the glass device using a highly corrosive chemical solution. The recovered glass device may then be reused.

An X-ray mask substrate includes a silicon wafer having a square, central region etched to a thin, tensile membrane and a highly tensile film deposited on the bottom surface of the substrate to reduce substrate warpage. The square, central region of the substrate is adapted to support X-ray absorbing material during the lithography process. A layer of highly tensile film such as tungsten is deposited on the lower side of the substrate to induce a bending moment on the substrate opposite that induced during the substrate fabrication process. The thickness of the film layer is directly proportional to the amount of warpage induced in the substrate during the fabrication process. A support ring is bonded to the peripheral region of the substrate to provide integrity and support.
