Barrier first method for single damascene trench applications

Methods for forming a diffusion barrier on low aspect features of an integrated circuit include at least three operations. The first operation deposits a barrier material and simultaneously etches a portion of an underlying metal at the bottoms of recessed features of the integrated circuit. The second operation deposits barrier material to provide some minimal coverage over the bottoms of the recessed features. The third operation deposits a metal conductive layer. Controlled etching is used to selectively remove barrier material from the bottom of the recessed features, either completely or partially, thus reducing the resistance of subsequently formed metal interconnects.

Apparatus and process for regenerating catalyst

Disclosed is an apparatus and process for prolonging the residence time of catalyst in a chamber for regenerating catalyst. Spent catalyst, perhaps from an FCC reactor, is introduced into a chamber of a regeneration vessel between lower and higher combustion gas distributors. The velocity of gas from the lower distributor is insufficient to entrain catalyst from the bed, and gas from the higher distributor when combined with gas rising from the lower distributor is sufficient to generate a fast fluidized flow condition. The second distributor elevates the location of the transition from turbulent bed to fast fluidized conditions.

User selection method in a zero-forcing beamforming algorithm

In a method for selecting a transmission target terminal in a zero-forcing beamforming algorithm, information about a channel capacity of each terminal is received from all K terminals. A terminal with a largest channel capacity is selected as an initial transmission target terminal. A determination is made as to whether the number of currently selected terminals, i, is equal to the predefined number N. If the number of currently selected terminals, i, is different from the predefined number N, information about channel capacities of remaining terminals except previously selected transmission target terminals is received until i is equal to N and a terminal with a largest channel capacity is selected as a transmission target terminal.
