    摘要: A method for forming a patterned target layer from a blanket target layer while employing a blanket photoresist layer in conjunction with an exposure method which is susceptible to a proximity effect employs when exposing the blanket photoresist layer to form an exposed blanket photoresist layer a main latent pattern and a second latent pattern adjacent the main latent pattern. Each patterned photoresist layer formed upon developing the main latent pattern is formed of a first linewidth such that not all of a first portion of the blanket target layer formed therebeneath is etched within an isotropic etchant which is employed for etching the blanket target layer to form the patterned target layer. In contrast, each patterned photoresist layer formed upon developing the second latent pattern is formed of a second linewidth such that all of a second portion of the blanket target layer formed therebeneath is etched within the isotropic etchant which is employed for etching the blanket target layer to form the patterned target layer. The method is particularly useful for efficiently forming a photomask while attenuating a proximity effect.

    摘要: A method is provided for improving layer to layer overlay of a second layer pattern on a first layer pattern formed in a substrate. A plurality of first reference marks is placed inside a pattern area on a first layer mask which is used to form the first layer pattern. A plurality of second reference marks is placed on a second layer mask which is used to form the second layer pattern and in which one second reference mark is matched with a first reference mark having the same (x,y) coordinates. Reference mark placement in the resulting first and second layer patterns is determined by metrology to determine an x-deviation and a y-deviation for each matched pair of reference marks. A correction algorithm is then used to calculate adjustments in exposure tool settings for improved overlay of the second layer pattern on the first layer pattern in subsequent exposures.

    摘要: The invention calculates an optimum etch recipe for etching a product pattern in an opaque material of a photolithographic exposure mask with the objective of achieving optimum CD performance of the product pattern. If, for this optimum etch recipe, the optimum CD performance cannot be achieved, dummy patterns are added to the mask that is used to etch the opaque material. If this latter approach still cannot achieve optimum CD performance, the product pattern to which the dummy pattern has been added is separated into two patterns such that one of these two patterns provides a Cr loading that assures optimum CD performance of the product pattern.

    摘要: This invention provides a method of using an electron beam exposure system having an electron beam with a variable shape to form patterns in a layer of resist on a substrate, a mask substrate or an integrated circuit wafer, while maintaining adequate critical dimension control and beam stability. This is accomplished by setting the electron beam to a fixed square beam with a width set to provide optimum XY critical dimension control for exposing a frame pattern surrounding the original pattern. The frame pattern has a width of a first distance and surrounds the outer perimeter of the original pattern. This provides optimum XY critical dimension control at the outer perimeter of the original pattern. The remainder of the exposure field, which is the exposure field with the original pattern and the frame pattern subtracted away is exposed using an electron beam having a variable size and shape. In one embodiment the exposure of the frame pattern is completed before the exposure of the remainder pattern is carried out. Alternatively, the exposure of the remainder pattern can be completed before the exposure of the frame pattern is carried out. The digital design data for the frame pattern and the remainder of the exposure field is formed using a computer processor and the original design data.
