    摘要: 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 or else used in a multi-surface imaging composition. 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.

    摘要: A method of fabricating a photomask having improved critical dimension (CD) uniformity that meets or exceeds 90 nanometer technology requirements. The method includes the steps of: providing a transparent substrate covered with a layer of opaque material and a layer of photoresist; patterning the layer of photoresist to expose an area of the layer of opaque material that has a shape that follows a contour of a main pattern area to be defined by the layer of opaque material; removing the exposed area to define the layer of opaque material into the main pattern area and an area that surrounds the main pattern area; removing the patterned layer of photoresist; and removing the surrounding area of the layer of opaque material.
