A method of manufacturing a semiconductor device includes forming a first tone resist layer over an underlayer. The first tone resist layer is pattern to form a first pattern exposing a portion of the underlayer. The first pattern is extended into the underlayer, and the first tone resist layer is removed. A second tone resist layer is formed over the underlayer, wherein the second tone is opposite the first tone. The second tone resist layer is patterned to form a second pattern exposing another portion of the underlayer. The second pattern is extended into underlayer, and the second tone resist layer is removed.

The present disclosure, in some embodiments, relates to a method of developing a photosensitive material. The method includes forming a photosensitive material over a substrate. The photosensitive material is exposed to electromagnetic radiation focused at a plurality of different heights over the substrate. The plurality of different heights are vertically separated from one another and are disposed within the photosensitive material along a vertical path that extends in a direction perpendicular to an upper surface of the photosensitive material. The photosensitive material is developed to remove a soluble region.

A method includes: depositing a mask layer over a substrate; directing first radiation reflected from a central collector section of a sectional collector of a lithography system toward the mask layer according to a pattern; directing second radiation reflected from a peripheral collector section of the sectional collector toward the mask layer according to the pattern, wherein the peripheral collector section is vertically separated from the central collector section by a gap; forming openings in the mask layer by removing first regions of the mask layer exposed to the first radiation and second regions of the mask layer exposed to the second radiation; and removing material of a layer underlying the mask layer exposed by the openings.

Systems and methods for custom photolithography masking via a precision dispense apparatus and process are disclosed. Methods include creating a toolpath instruction for depositing opaque onto a substrate, programming a precision dispense apparatus to execute the created toolpath instruction, and causing the precision dispense tool to deposit opaque material onto the substrate to form the photomask. The substrate may be an optically transparent plate or film or may be an electronic substrate where the opaque material is deposited directly onto a photoresist coating. Capabilities of the systems and methods disclosed herein extend to 3D substrates and custom photolithography masking, among others.

A substrate treating apparatus and a substrate treating method are provided. The substrate treating apparatus comprises: a process chamber; a support member positioned in an inner space of the process chamber to support the substrate; an exhaust line provided to communicate with the interior of the process chamber; an exhaust member for providing a suction pressure to the exhaust line; and a controller for controlling the exhaust member when dividing the substrate treating step in which the treating for the substrate is performed into the first treating step and the second treating step, a difference is generated between the pressure that the exhaust member provides to the exhaust line in the first treating step and the pressure that the exhaust member provides to the exhaust line in the second treating step.

A method of manufacturing a semiconductor device structure is provided. The method includes: providing a substrate; forming a photoresist layer on the substrate; patterning the photoresist layer to form a patterned photoresist layer; forming a pitch adjustment layer on the patterned photoresist layer to define a mask pattern; and determining whether the mask pattern meets a specification of semiconductor fabrication processes; when it is determined that the mask does not meet the specification of semiconductor fabrication processes, performing a rework operation to remove the pitch adjustment layer.

A method for preparing a semiconductor device structure is provided. The method includes forming a target layer over a semiconductor substrate, and forming an energy-sensitive layer over the target layer. The method also includes performing an energy treating process on the energy-sensitive layer to transform a portion of the energy-sensitive layer into a treated portion. An untreated portion of the energy-sensitive layer is surrounded by the treated portion. The method further includes removing the treated portion, and transferring a pattern of the untreated portion of the energy-sensitive layer to the target layer such that the semiconductor substrate is exposed.

In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.

This manufacturing method of a metal component enables precision processing of a corner portion, and the radius of curvature of a cog tip of a gear and the like can be made smaller than before. The manufacturing method of a metal component includes: (a) forming a mask film having, in plan view, a first side, a second side, and an extension portion that extends from a region between the first side and the second side on a metal film; and (b) forming a corner portion having, in plan view, a third side and a fourth side by etching the metal film.
