摘要: A static resistant reticle comprises a substrate and a patterning layer and is covered by an antistatic conductive film of quaternary amine (R4N)+Cl−. A pellicle structure comprising an optically transparent membrane tightly stretched on a frame is also coated by an antistatic electro conductive film of a similar material. The reticle with the pellicle form a shielded structure isolating the reticle from ESD.

摘要: A pod for transporting reticles is made with a reticle support that has a Π-shape and is provided with pins, whose arrangement matches the location of chrome-free areas on a reticle base. Due to that, the pins, when supporting the reticle, come into contact with the reticle in chrome-free areas thereof. Thus, scratching the metallic areas and releasing metallic particles is prevented from occurring.

摘要: An electrostatic discharge-free container equipped with a metal shield for holding an insulating article therein is described. In the container, an electrically conductive layer substantially covers a bottom lid made of a non-conductive material so as to sufficiently shield the insulating article from electrostatic discharge damages. The present invention novel ESD-free container may further be provided with a metal knob situated in a top lid of the container, or be provided with a metal enclosure positioned inside the container between the top lid and the insulating article. The metal layer that substantially overlaps the bottom lid may be injection molded as an insert in the bottom lid, or may be coated or plated on the bottom lid. The present invention novel ESD-free container eliminates any electrostatic discharge from occurring on a reticle plate and thus avoiding any potential damages. The present invention ESD-free reticle pod may be easily modified from existing reticle pod and therefore provides a low cost retrofit method for providing ESD-free containers.

摘要: A method of photomask reticle design provides for greatly increased tolerance to adjacent exposure field alignment and/or stepper magnification errors, thus eliminating gaps between adjacent exposure fields in the fabrication of semiconductor integrated circuit devices.The resulting insurance of complete exposure of photoresist eliminates the formation of non-exposed unwanted photoresist residues or stringers, which constitute defects in the manufacture of such devices.

摘要: The present disclosure provides for methods of reducing cycle time in data preparation. In one embodiment, a method includes receiving an initial integrated circuit (IC) design layout and an optical proximity correction (OPC)-processed initial IC design layout, and receiving a revised IC design layout. The method further includes comparing the revised IC design layout to the initial IC design layout to identify a difference region of the revised IC design layout from the initial IC design layout, performing an OPC on the difference region of the revised IC design layout, and merging the OPC-processed difference region of the revised IC design layout with the OPC-processed initial IC design layout.
