  • Publication number: 20130269780
    Abstract: The present invention relates to a method for fabricating a thin layer made of a alloy and having photovoltaic properties. The method according to the invention comprises first steps of: a) depositing an adaptation layer (MO) on a substrate (SUB), b) depositing at least one layer (SEED) comprising at least elements I and/or III, on said adaptation layer. The adaptation layer is deposited under near vacuum conditions and step b) comprises a first operation of depositing a first layer of I and/or III elements, under same conditions as the deposition of the adaptation layer, without exposing to air the adaptation layer.

  • Publication number: 20070105241
    Abstract: A method of forming a ferromagnetic liner on conductive lines of magnetic memory devices and a structure thereof. The ferromagnetic liner increases the flux concentration of current run through the conductive lines, reducing the amount of write current needed to switch magnetic memory cells. The conductive lines are formed in a plate-up method, and the ferromagnetic liner is selectively formed on the plated conductive lines. The ferromagnetic liner may also be formed over conductive lines and a top portion of vias in a peripheral region of the workpiece.

  • Publication number: 20060222871
    Abstract: The present invention provides an electrodeposition/plating method for metal films and alloys in a bath which contain ferric ions and which usually deposit with high stress, but which when electrodeposited under pulse plating conditions in the presence of low valence vanadium or other ions capable of existing in multiple valence states produce low stress films and alloys and furthermore when plated through a mask creep laterally through walls and creep laterally along the surface of the mask to permit formation of overhangers, bridges, heat exchangers, and other complex three dimensional micro structures of low stress.
