International Classification:

H01L 2348

US Classification:

257773, 257775, 257765

Abstract:

A process for producing a multi-level semiconductor device having metal interconnections with insulating passivation layers and the product produced thereby. The product and process improve the resistance of the metallization interconnections to extrusion-short electromigration failures by preventing the insulating passivation layers from cracking. The product and process also reduce the level of resistance saturation or the maximum resistance shift caused by electromigration. By replacing wide-line metallization interconnection conducting lines surrounded by insulating passivation layers with two or more narrow, parallel conducting lines having aspect ratios less than or equal to unity with passivation layers located in between, the incidence of passivation cracking and extrusion-short failures is reduced. The process is especially suited for use in multi-level wiring structures in which the wiring levels have diffusion barriers between the wiring levels caused by redundant metallization layers, interlevel connections, or both.

International Classification:

C03B 3708

US Classification:

65495, 65499

Abstract:

A bushing including a terminal ear and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body which can include side plates, end plates, a bottom plate, and terminal ears coupled to the bushing body. Clamps are attached to the terminal ears to supply electrical current to the bushing to maintain the glass inside in a liquid state. Each terminal ear includes an upper portion and a lower portion. The upper portion is coupled to a side plate of the bushing. A clamp is attached to the lower portion of the terminal ear. The upper and lower portions are oriented at an angle with respect to each other. Support portions are provided along the side edges of the upper portions of the terminal ears. Support portions stiffen the terminal ear, thereby increasing its resistance to bending and fatigue stresses. Support portions do not contact the bushing and therefore do not directly conduct current to the bushing.

International Classification:

C03B 3709

US Classification:

65495, 65499

Abstract:

A screen comprises an electrically conductive elongate inner screen plate. The inner screen plate has at least one elongate fold therein and at least two elongate divergent surfaces on opposing sides of the fold. Each divergent surface has an upper end and opposing edges tapering downward from the upper end. The upper ends of the divergent surfaces diverge from one another. Each of the divergent surfaces has a plurality of holes therein. The screen further comprises at least two electrically conductive outer screen plates. The outer screen plates are attached to the edges of the divergent surfaces and extend between the divergent surfaces. Each of the outer screen plates has a plurality of holes therein. Another embodiment of the invention is directed toward a glass fiber bushing system comprising a bushing body and a screen within the bushing body. The bushing body has opposing end plates.

International Classification:

C03B 3708

US Classification:

65495, 65492, 373 28

Abstract:

A bushing assembly/support structure arrangement is provided. The arrangement comprises a bushing assembly and a support structure. The bushing arrangement includes a bushing main body comprising at least first and second side walls and a tip plate extending between the side walls. The tip plate contains a plurality of orifices through which molten mineral material flows prior to being attenuated into fibers. The bushing assembly further comprises a first support rail coupled to the main body first side wall, and at least one first bracket having an intermediate member coupled to the main body first side wall. The support structure comprises a bushing frame, and at least one first support strap. The support strap has a first end fixedly coupled to the bushing frame and second end extending toward a first location on the support rail adjacent the first bracket for supporting the bushing assembly.

Abstract:

A plurality of different structural members for reinforcing a plate-like structure, such as a bushing tip plate for intended use in forming fibers from a fluid material supplied to a bushing assembly, are disclosed. Each reinforcing member includes a body having a first portion for attachment to the structure and a second portion having a profile with a variable height including at least one apex. The body may be integrally formed of a single piece of material, or two or formed from more separate pieces of material bonded or secured together. The body may be T-shaped, L-shaped, or F-shaped in cross-section. The second portion of the body may have an inverted V-shaped profile, an inverted W-shaped profile, or an arcuate profile. The at least one apex may be located at the midpoint or elsewhere along the length of the body.
