A hologram reticle and method of patterning a target. A layout pattern for an image to be transferred to a target is converted into a holographic representation of the image. A hologram reticle is manufactured that includes the holographic representation. The hologram reticle is then used to pattern the target. Three-dimensional patterns may be formed in a photoresist layer of the target in a single patterning step. These three-dimensional patterns may be filled to form three-dimensional structures. The holographic representation of the image may also be transferred to a top photoresist layer of a top surface imaging (TSI) semiconductor device, either directly or using the hologram reticle. The top photoresist layer may then be used to pattern an underlying photoresist layer with the image. The lower photoresist layer is used to pattern a material layer of the device.

Combined e-beam and optical exposure lithography for semiconductor fabrication is disclosed. E-beam direct writing to is employed to create critical dimension (CD) areas of a semiconductor design on a semiconductor wafer. Optical exposure lithography is employed to create non-CD areas of the semiconductor design on the semiconductor CD's of the semiconductor design can also be separated from non-CD's of the semiconductor design prior to employing e-beam direct writing and optical exposure lithography.

摘要:
The present invention is related to methods of processing a semiconductor device. A plasma vapor deposition process is used to fill a trench with an oxide layer, wherein sharp corners are formed by the oxide layer. A pre-planarization sputtering process is performed to reduce the oxide layer corner sharpness. A planarization process is performed using polishing.
摘要:
A method for producing a pattern on a substrate includes providing at least one exposure of the pattern onto a layer of the substrate by a higher-precision lithography mechanism and providing at least one exposure of the pattern onto a layer of the substrate by a lower-precision lithography mechanism. The exposures can be done in either order, and additional exposures can be included. The higher-precision lithography mechanism can be immersion lithography and the lower-precision lithography mechanism can be dry lithography.
摘要:
A method for forming an etch-resistant photoresist pattern on a semiconductor substrate is provided. In one embodiment, a photoresist layer is formed on the substrate. The photoresist layer is exposed and developed to form a photoresist pattern. A polymer-containing layer is formed over the photoresist pattern. The photoresist pattern and the polymer-containing layer are thermally treated so that polymer is substantially diffused into the photoresist pattern thereby enhancing the etch resistance of the photoresist pattern. The polymer-containing layer is thereafter removed.

A progressive self-learning (PSL) method is provided for enhancing wafer or mask defect inspection review and classification by identifying a plurality of wafer or mask defects, and by classifying each of the plurality of defects according to an extent of resemblance of each defect. The method having the steps of: performing image processing on a scanned defect image; aligning the scanned defect image with a just-stored digitized defect image; matching the scanned defect image with a just-stored digitized defect image; and classifying the scanned defect image.
