Abstract: A dual damascene conductor structure is formed on a substrate with an exposed conductor on top covered by a buried cap, a dielectric layer (DL) and an organic layer (OL). Form a lower via hard mask layers over the OL and form a top trench patterning hard mask over the lower, via hard mask. Form a trench pattern hole through the trench hard mask layer; and form a via pattern hole through the via hard mask layer in a region exposed below the trench pattern hole. Etch a via pattern hole into the OL and then etch a via pattern hole down into the DL. Etch away the trench pattern layer and the OL layer below the trench pattern hole. Etch the via hole through the DL exposing the cap while simultaneously partially etching the DL to a final trench depth to form a trench in the DL below the trench pattern hole, with the trench having a bottom above the cap and sidewalls in the DL.

Abstract: A method for implementing dual damascene processing includes forming a first hardmask layer over an interlevel dielectric layer, and forming a second hardmask layer over the first hardmask layer. A trench pattern is opened within a third hardmask layer formed over the second hardmask. A first etch process is implemented so as to define a via pattern completely through the second hardmask layer and partially through the first hardmask layer, and a second etch process is implemented to transfer the trench pattern and the via pattern into the interlevel dielectric layer.

Abstract: A method for forming an interconnect structure in a semiconductor device includes defining a first insulator layer on a substrate and defining a via in the first insulator layer, thereby exposing a portion of the substrate. A sacrificial material is deposited over the first insulator layer and within the via, the sacrificial material being deposited at a thickness so as to also form a second insulator layer. A metallization line trench is defined in the second insulator layer, the trench being aligned over the via. Then, the sacrificial material is removed from the via opening, thereby allowing the via and the trench to be filled with a conductive material by dual damascene processing, wherein the formation of the trench and the removal of the sacrificial material from the via is implemented through a single etching operation.

The aqueous slurry according to the invention includes abrasive particles and an organic compound having both a carboxylic acid functional group and a second functional group selected from amines and halides. The present invention also relates to a method of removing silicon dioxide in preference to silicon nitride from a surface of an article by chemical-mechanical polishing. The method includes polishing the surface using a polishing pad, water, abrasive particles, and an organic compound having both a carboxylic acid functional group and a second functional group selected from amines and halides. The abrasive particles can be dispersed in the aqueous medium or they can be bonded to the polishing pad.

Abstract: A method and apparatus of forming adjacent, non-overlapping CCD electrodes within an image sensing device such the electrodes are U-shaped. The device provided by the disclosed method employs a substrate with a gate dielectric layer formed on a surface of the substrate with a plurality of phases created within the CCD. A deposited silicon layer is placed on the surface of the CCD and a mask is used to cover areas other than the first set of electrodes. Etching takes places leaving the mask areas to the deposited silicon and a set of side walls to the remaining deposited silicon are then oxidized. A first set of electrodes by forming an electrode layer placed over the CCD. CMP is employed to remove remaining deposited silicon layer as well as portions of the electrode layer such that the side walls remain vertical portions to electrode layer remaining in the side walls. The process is then repeated by placing another electrode material layer and another CMP process leaving two sets of adjacent U-shaped gates.

Abstract: A laminated structure includes a wafer member with a membrane attached thereto, the membrane being formed of substantially hydrogen-free boron nitride having a nominal composition B.sub.3 N. The structure may be a component in a mechanical device for effecting a mechanical function, or the membrane may form a masking layer on the wafer. The structure includes a body formed of at least two wafer members laminated together with a cavity formed therebetween, with the boron nitride membrane extending into the cavity so as to provide the structural component such as a support for a heating element or a membrane in a gas valve. In another aspect borom is selectively diffused from the boron nitride into a <100> surface of a silicon wafer. The surface is then exposed to EDP etchant to which the diffusion layer is resistant, thereby forming a channel the wafer member with smooth walls for fluid flow.

Abstract: A microdevice assembly includes a miniature fluid processing device of silicon with a fluid orifice therein. A high-silica glass attachment member sealed to the device has an aperture with a narrow portion aligned with the orifice and a conical portion with a conical wall diverging from the narrow portion. A tube with a soft graphite ferrule thereon is inserted into the conical portion. A rigid package member includes a base supporting the device, a cover disposed proximate the attachment member, and side walls connecting the base and the cover. A threaded opening through the cover is aligned with the aperture. An externally threaded nut with a hole therethrough is fitted slidingly over the tube, and is tightened into the threaded opening so as to sealingly compress the ferrule between the wall and the tube.
