Recesses in a semiconductor structure are selectively plated by providing electrical insulating layer over the semiconductor substrate and in the recesses followed by forming a conductive barrier over the insulating layer; providing a plating seed layer over the barrier layer; depositing and patterning a photoresist layer over the plating seed layer; planarizing the insulated horizontal portions by removing the horizontal portions of the seed layer between the recesses; removing the photoresist remaining in the recesses; and then electroplating the patterned seed layer with a conductive metal using the barrier layer to carry the current during the electroplating to thereby only plate on the seed layer. In an alternative process, a barrier film is deposited over recesses in an insulator. Then, relatively thick resists are lithographically defined on the field regions, on top of the barrier film over the recesses. A plating base or seedlayer is deposited, so as to be continuous on the horizontal regions of the recesses in the insulator, but discontinuous on their surround wall. The recesses are then plated using the barrier film without seedlayers at the periphery of the substrate wafers for electrical contact. After electroplating, the resist is removed by lift-off process and exposed barrier film is etched by RIE method or by CMP. Also provided is a semiconductor structure obtained by the above processes.

Front end of line (FEOL) plasma mediated ashing processes for removing organic material from a substrate generally includes exposing the substrate to the plasma to selectively remove photoresist, implanted photoresist, polymers and/or residues from the substrate, wherein the plasma contains a ratio of active nitrogen and active oxygen that is larger than a ratio of active nitrogen and active oxygen obtainable from plasmas of gas mixtures comprising oxygen gas and nitrogen gas. The plasma exhibits high throughput while minimizing and/or preventing substrate oxidation and dopant bleaching. Plasma apparatuses are also described.

Method and apparatus for etching a metal layer disposed on a substrate, such as a photolithographic reticle, are provided. In one aspect, a method is provided for processing a photolithographic reticle including positioning the reticle in a first orientation on a reticle support in a processing chamber, wherein the reticle comprises a metal photomask layer formed on an optically transparent substrate, and a patterned resist material deposited on the metal photomask layer, etching the metal photomask layer in the first orientation, positioning the reticle in at least a second orientation, and etching the metal photomask layer in the at least second orientation.

A resist pattern is formed on a to-be-processed film. Ions are implanted in the upper surface of the resist pattern. After ion implantation, an organic film is formed to cover the resist pattern and heated. A crosslinked resin film made of the organic film which has crosslinked is formed on the sidewall of the resist pattern by developing the organic film after heating. After formation of the crosslinked resin film, the resist pattern is removed. The to-be-processed film is processed using the crosslinked resin film as a mask.

Methods and apparatuses to improve the temperature uniformity of a workpiece being processed on a heated platen of a thermal processing station. A heated platen is enclosed in a housing incorporating an additional heat source that uniformly outputs thermal energy into the process chamber in which the heated platen is positioned. In preferred embodiments, this heat source is positioned in the lid of the housing. It is additionally preferred that the heated lid includes features that provide a gas flow path to introduce to and/or purge gas from the process chamber. In terms of photoresist performance, the improved thermal uniformity provided by using such an additional heat source in the housing, e.g., in the lid, offers improved line width control and line uniformity across a wafer.

In a mask pattern forming method, a resist film is formed over a thin film, the resist film is processed into resist patterns having a predetermined pitch by photolithography, slimming of the resist patterns is performed, and an oxide film is formed on the thin film and the resist patterns after an end of the slimming step in a film deposition apparatus by supplying a source gas and an oxygen radical or an oxygen-containing gas. In the mask pattern forming method, the slimming and the oxide film forming are continuously performed in the film deposition apparatus.

A method is provided for forming an improved interconnect structure on a semiconductor body. A first metal layer is deposited on the semiconductor body. A sacrificial layer having a height is deposited on the first metal layer. The sacrificial layer and the metal layer are patterned to form separate metal lines with the sacrificial layer remaining on said metal lines. A low-k material is then deposited to fill the gaps between metal lines and to cover the sacrificial layer. The low-k material is then removed to a level within the height of the sacrificial layer. The sacrificial layer is then removed. A protective layer is deposited on top of the metal lines and the low-k material. A dielectric layer is deposited over the protective layer. The protective layer protects the low-k material from attack by chemicals utilized by subsequent process steps to etch vias in the dielectric layer, to strip photo-resist, and to clean the vias. The protective layer is then selectively etched away to make contact between a via plug and the metal lines.

The invention provides a display device in which parasitic capacitance associated with data lines and driving circuits is prevented using a bank layer whose primary purpose is to define areas on a substrate in which an organic semiconductor film is formed. When the organic semiconductor film for forming a luminescent element such as an electroluminescent element or an LED is formed is formed in pixel regions (7), the organic semiconductor film is formed in the areas surrounded by the bank layer (bank) formed of a black resist. The bank layer (bank) is also formed between an opposite electrode (op) and data lines (sig) for supplying an image signal to first TFTs (20) and holding capacitors (cap) in the pixel regions (7) thereby preventing parasitic capacitance associated with the data lines (sig).

There is provided a semiconductor device manufacturing method for forming a step-shaped structure in a substrate by etching the substrate having thereon a multilayer film and a photoresist film on the multilayer film and serving as an etching mask. The multilayer film is formed by alternately layering a first film having a first permittivity and a second film having a second permittivity different from the first permittivity. The method includes a first process for plasma-etching the first film by using the photoresist film as a mask; a second process for exposing the photoresist film to hydrogen-containing plasma; a third process for trimming the photoresist film; and a fourth process for etching the second film by using the trimmed photoresist film and the plasma-etched first film as a mask. The step-shaped structure is formed in the multilayer film by repeatedly performing the first process to the fourth process in this sequence.
