    摘要: Provided is a lithography system that includes a source for providing energy, an imaging system configured to direct the energy onto a substrate to form an image thereon, and a diffractive optical element (DOE) incorporated with the imaging system, the DOE having a first dipole located in a first direction and a second dipole located in the first direction or a second direction perpendicular the first direction. The first dipole includes a first energy-transmitting region spaced a first distance from a center of the DOE. The second dipole includes a second energy-transmitting region spaced a second distance from the center of the DOE. The first distance is greater than the second distance.

    摘要: The overlay mark and method for making the same are described. In one embodiment, a semiconductor overlay structure includes gate stack structures formed on the semiconductor substrate and configured as an overlay mark, and a doped semiconductor substrate disposed on both sides of the gate stack structure that includes at least as much dopant as the semiconductor substrate adjacent to the gate stack structure in a device region. The doped semiconductor substrate is formed by at least three ion implantation steps.

    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: Apparatus and methods are disclosed herein for fabricating semiconductor device features with a half-pitch node of 22 nm and beyond using single exposure and single etch (1P1E) photolithography techniques. The method includes exposing in a single exposure a photoresist layer to the exposure source through a photolithography mask where the photolithography mask has on it an island pattern of a material having high percentage transmission. The photoresist layer is developed using a negative tone developer to form a hole pattern in the photoresist layer. The 1P1E does not require the second photo exposure of the double patterning method. Furthermore, the method circumvents the island pattern collapsing issues and the need for strong illumination associated with exiting single 1P1E processes.
