International Classification:

B01D 15/08

US Classification:

2101982, 2105021, 210635, 210656, 502404

Abstract:

The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.

International Classification:

C25D 3/38

US Classification:

205157

Abstract:

A method for metallizing a through silicon via feature in a semiconductor integrated circuit device substrate. The method comprises immersing the semiconductor integrated circuit device substrate into an electrolytic copper deposition composition, wherein the through silicon via feature has an entry dimension between 1 micrometers and 100 micrometers, a depth dimension between 20 micrometers and 750 micrometers, and an aspect ratio greater than about 2:1; and supplying electrical current to the electrolytic deposition composition to deposit copper metal onto the bottom and sidewall for bottom-up filling to thereby yield a copper filled via feature. The deposition composition comprises (a) a source of copper ions; (b) an acid selected from among an inorganic acid, organic sulfonic acid, and mixtures thereof; (c) an organic disulfide compound; (d) a compound selected from the group consisting of a reaction product of benzyl chloride and hydroxyethyl polyethyleneimine, a quaternized dipyridyl compound, and a combination thereof; and (d) chloride ions.
