    摘要: The present disclosure relates to the technical field of semiconductors, and provides a method of processing a photoresist layer, and a photoresist layer. The method of processing a photoresist layer includes: forming a photoresist layer on a target layer, where the photoresist layer includes a first part close to the target layer and a second part away from the target layer; performing first exposure processing on the photoresist layer, and forming an exposure image in the first part of the photoresist layer; processing the second part of the photoresist layer by using a first process, such that the second part forms a third part, where a photosensitivity of the third part is higher than that of the first part; and stripping the third part.

    摘要: Provided is a method and system for stripping an ion implanted resist or performing a post-ash clean using a single substrate tool. Cleaning objectives and cleaning operating variables are selected for optimization. The first step immerses the substrate in a first treatment chemical, while concurrently irradiating the substrate with UV light, the process completed in a first process time, a first flow rate, and a first rotation speed of the substrate. The second step dispenses onto the substrate a second treatment chemical at a second temperature and a second composition, the second treatment chemical dispensed at a dispense temperature, and completed in a second process time and a second rotation speed. The two or more selected cleaning operating variables comprise UV wavelength, UV power, first concentration, first rotation speed, first flow rate, second process time, second rotation speed, percentage of residue removal, and dispense temperature.

    摘要: Among other things, one or more systems and techniques for removing a photoresist from a semiconductor wafer are provided. The photoresist is formed over the semiconductor wafer for patterning or material deposition. Once completed, the photoresist is removed in a manner that mitigates damage to the semiconductor wafer or structures formed thereon. In an embodiment, trioxygen liquid is supplied to the photoresist. The trioxygen liquid is activated using an activator, such as an ultraviolet activator or a hydrogen peroxide activator, to create activated trioxygen liquid used to remove the photoresist. In an embodiment, the activation of the trioxygen liquid results in free radicals that aid in removing the photoresist. In an embodiment, an initial photoresist strip, such as using a sulfuric acid hydrogen peroxide mixture, is performed to remove a first portion of the photoresist, and the activated trioxygen liquid is used to remove a second portion of the photoresist.

    摘要: A light irradiation device includes a workpiece support onto which a workpiece (object to be processed) is placed, an ultraviolet lamp for emitting a vacuum ultraviolet beam to a target surface (surface to be processed) of the workpiece, and a light transmitting window member disposed between the workpiece and the ultraviolet lamp and configured to pass the vacuum ultraviolet beam from the ultraviolet lamp therethrough. A gap defined between the target surface of the workpiece and the light transmitting window member is no greater than 1 mm. A gas supply unit is provided for supplying a processing gas into the gap such that the gas travels along the target surface in one direction. A gas blocking member is provided on the workpiece support in a region where the workpiece is not present. The region extends along a supply direction of the processing gas.

    摘要: The embodiments disclosed herein pertain to novel methods and apparatus for removing material from a substrate. In certain embodiments, the method and apparatus are used to remove negative photoresist, though the disclosed techniques may be implemented to remove a variety of materials. In practicing the disclosed embodiments, a stripping solution may be introduced from an inlet to an internal manifold, sometimes referred to as a cross flow manifold. The solution flows laterally through a relatively narrow cavity between the substrate and the base plate. Fluid exits the narrow cavity at an outlet, which is positioned on the other side of the substrate, opposite the inlet and internal manifold. The substrate spins while in contact with the stripping solution to achieve a more uniform flow over the face of the substrate. In some embodiments, the base plate includes protuberances which operate to increase the flow rate (and thereby increase the local Re) near the face of the substrate.
