    摘要: The process for the fabrication of an electronic device has the steps of forming a layer to be etched on top of a substrate in a wafer of semiconductor material; depositing a masking layer; and carrying out a plasma etch to define the geometry of the layer to be etched. The masking layer is made so as to be conductive, at least during one part of the etching step; in this way, the electrons implanted on the top part of the masking layer during plasma etching can recombine with the positive charges which have reached the layer to be etched. The recombination of the charges makes it possible to prevent damage from plasma resulting from the formation of parasitic electric currents which are detrimental to the electronic device itself.

    摘要: The current invention provides methods for performing a cleaning process that provides greater cleaning efficiency with less damage to device structures. After etching and photoresist stripping, a first plasma clean is performed. The first plasma clean may comprise one or more steps. Following the first plasma clean, a first HO based clean is performed. The first HO based clean may be a de-ionized water rinse, a water vapor clean, or a plasma clean, where the plasma includes hydrogen and oxygen. Following the first HO based clean, a second plasma clean is performed, which may comprise one or more steps. A second HO based clean follows the second plasma clean, and may be a de-ionized water rinse, a water vapor clean, or a plasma clean, where the plasma includes hydrogen and oxygen. For plasma processes, an RF generated plasma, a microwave generated plasma, an inductively coupled plasma, or combination may be used. Embodiments of the invention are performed after an etch, such as a metal etch, via etch, contact etch, polysilicon etch, nitride etch or shallow trench isolation etch has been performed. Photoresist may be removed either prior to, during, or after cleaning processes according to embodiments of the invention, using an oxygen-containing plasma. Photoresist removal may be performed at low temperatures.

    摘要: A method enhances selectivity between a film of a light-sensitive material and a layer to be subjected to etching in the course of fabrication processes of an electronic semiconductor device starting from a semiconductor material wafer. The method includes radiating the wafer with an ion beam subsequently to depositing the layer to be etched and defining a circuit pattern on the film of light-sensitive material. An alternative method exposes the wafer to a non-reactive gas medium under plasma rather than radiating the wafer with an ion beam.
