Abstract:
A method and apparatus for coating a surface of a substrate using combustion chemical vapor deposition is disclosed. A chemical vapor deposition stream, composed of a coating precursor and a combustible medium, is directed toward a substrate and combusted to provide a reacted coating precursor in a gaseous plume. The plume is modified by exposing it to a shield prior to the plume contacting the surface of the substrate and depositing a coating thereon. The shield serves to control the coating thickness and material characteristics of the deposited material.
Abstract:
Methods of preparing Group IVA and Group VIA organometallic compounds, particularly Group IVA organometallic compounds, are provided. Such manufacturing methods employ an amine and/or phosphine catalyst in a transalkylation step and may be performed in a batch, semi-continuous or continuous manner.
Abstract:
Disclosed are electrolyte compositions for depositing a tin alloy on a substrate. The electrolyte compositions include tin ions, ions of one or more alloying metals, an acid, a thiourea derivative, and an additive selected from alkanol amines, polyethylene imines, alkoxylated aromatic alcohols, and combinations thereof. Also disclosed are methods of depositing a tin alloy on a substrate and methods of forming an interconnect bump on a semiconductor device.
Abstract:
Compositions useful for the removal of polymeric material from substrates, such as magnetoresistive sensors, are provided. Methods of removing such polymeric material from magnetoresistive sensors and methods of manufacturing magnetoresistive sensors are also provided.
Abstract:
Germanium compounds suitable for use as vapor phase deposition precursors for germanium films are provided. Methods of depositing films containing germanium using such compounds are also provided. Such germanium films are particularly useful in the manufacture of electronic devices.
Abstract:
Provided are coaxial waveguide microstructures. The microstructures include a substrate and a coaxial waveguide disposed above the substrate. The coaxial waveguide includes: a center conductor; an outer conductor including one or more walls, spaced apart from and disposed around the center conductor; one or more dielectric support members for supporting the center conductor in contact with the center conductor and enclosed within the outer conductor; and a core volume between the center conductor and the outer conductor, wherein the core volume is under vacuum or in a gas state. Also provided are methods of forming coaxial waveguide microstructures by a sequential build process and hermetic packages which include a coaxial waveguide microstructure.
