摘要:
A distributor with controlled switching elements (CSE) which simplifies hardware construction by distributing the function of a running adder into a reverse banyan network. The distributor comprises a CSE-based network using switching stages, each switching stage having control switching elements. A control signal input stage switches two packet input signal switching channels, each stage receiving each control signal from an output stage having switching elements. An active packet counter counts and generates an output signal which represents the number of active packets inputted to the CSE network. A tail-of-queue register is used for storing output vectors.

A round heating plate for a heating chamber used in semiconductor device manufacturing provides uniform heating of the wafer from its center to its outside edges. The round heating plate includes a small-diameter round heating element and multiple ring-shaped elements arranged concentrically therewith. The round heating plate has the same shape as the wafer, and in the heating chamber, a pair of round heating plates is arranged so as to be concentric with a pair of wafers to be heated. During heating, the wafers are installed in a space formed between the heating plates.

A developing solution feed system for a semiconductor photolithography process feeds the developing solution while removing any gas contained in the solution at a high solution feed pressure. The developing solution feed system has a plurality of feed tanks and a developing solution feed line having a plurality of first connecting pipes, each connected to the feed tanks, a second connecting pipe connected to the first connecting pipe to be converged into one passage, and a plurality of third connecting pipes branching out from the second connecting pipe. The system also contains nozzles connected to the third connecting pipes to thereby sputter the developing solution onto wafers each located in process chambers, a gas removal device installed in the one passage of the second connecting pipe to thereby remove gas contained in the developing solution, and shut off valves, each installed in the third connecting pipes to thereby open and close passages, so that the developing solution can selectively be fed into only one process chamber at a time through the third connecting pipes.

A method of forming an integrated circuit capacitor includes the steps of forming an insulating layer on an integrated circuit substrate, and forming a conductive layer on the insulating layer opposite the integrated circuit substrate. A patterned ozone tetraethylorthosilicate undoped silicate layer is formed on the conductive layer, and conductive spacers are formed along sidewalls of the ozone tetraethylorthosilicate undoped silicate layer. A dielectric layer is formed on the conductive spacers and on the first conductive layer, and a second conductive layer is formed on the dielectric layer opposite the first conductive layer in the conductive spacers.

of A method of forming a dielectric layer includes the steps of forming an electrode on a microelectronic substrate, and forming depressions and protrusions on exposed portions of the electrode thereby increasing a surface area thereof. An exposed portion of the electrode including the depressions and protrusions is nitrified, and the electrode is not exposed to oxygen during and between the steps of forming the depressions and protrusions and nitrifying the exposed portion of the electrode. A nitride layer is then formed on a nitrified electrode. Related structures are also discussed.

A dry etching method and apparatus improves the uniformity of etching a wafer in the manufacture of a semiconductor device. The dry etching apparatus has a susceptor supporting the wafer, a cooling system installed in the susceptor, an upper RF (radio frequency) electrode which may incorporate a gas diffuser for spraying reactive gas toward the wafer, and an RF power source for producing an electric field used to react the gas and generate plasma. The gap between the upper RF electrode and the susceptor is configured to accommodate for distortions in the wafer or other processing requirements. In addition, the nozzles of the gas diffuser can be configured to spray different amounts of gas to also enhance the etching uniformity. Finally, one of the electrodes may be divided into concentric sections. In this case, the RF power source can generate electric fields of different intensities at the sections. When the divided electrode is the susceptor, the cooling system cools the sections to different temperatures to in turn temperature-condition the wafer in a manner determined in advance to enhance the uniformity of the etching process.
