A method of forming a silicon oxide layer on a substrate. The method includes providing a substrate and forming a first silicon oxide layer overlying at least a portion of the substrate, the first silicon oxide layer including residual water, hydroxyl groups, and carbon species. The method further includes exposing the first silicon oxide layer to a plurality of silicon-containing species to form a plurality of amorphous silicon components being partially intermixed with the first silicon oxide layer. Additionally, the method includes annealing the first silicon oxide layer partially intermixed with the plurality of amorphous silicon components in an oxidative environment to form a second silicon oxide layer on the substrate. At least a portion of amorphous silicon components are oxidized to become part of the second silicon oxide layer and unreacted residual hydroxyl groups and carbon species in the second silicon oxide layer are substantially removed.

Modular fluidic microchips, systems integrating such microchips, and associated preparative and analytical methods are presented.

A method for forming a conductive thin film includes depositing a metal oxide thin film on a substrate by an atomic layer deposition (ALD) process. The method further includes at least partially reducing the metal oxide thin film by exposing the metal oxide thin film to a gaseous inorganic reducing agent, thereby forming a metal layer. In preferred arrangements, the reducing agent comprises of thermal hydrogen (H2), hydrogen radicals (H*) and / or carbon monoxide (CO).

This invention relates to an electrophoretic display comprising cells of well-defined shape, size and aspect ratio, which cells are filled with charged pigment particles dispersed in a solvent, and novel processes for its manufacture.

The formation of through silicon vias (TSVs) in an integrated circuit (IC) die or wafer is described in which the TSV is formed in the integration process prior to metallization processing. TSVs may be fabricated with increased aspect ratio, extending deeper in a wafer substrate. The method generally reduces the risk of overly-thinning a wafer substrate in a wafer back-side grinding process typically used to expose and make electrical contacts to the TSVs. By providing deeper TSVs and bonding pads, individual wafers and dies may be bonded directly between the TSVs and bonding pads on an additional wafer.

A method for forming a conductive thin film includes depositing a metal oxide thin film on a substrate by an atomic layer deposition (ALD) process. The method further includes at least partially reducing the metal oxide thin film by exposing the metal oxide thin film to a reducing agent, thereby forming a seed layer. In one arrangement, the reducing agent comprises one or more organic compounds that contain at least one functional group selected from the group consisting of —OH, —CHO, and —COOH. In another arrangement, the reducing agent comprises an electric current.
