    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 of patterning an integrated circuit including generating a thermal profile of a reticle is provided. The thermal profile of the reticle may illustrate heat accumulation (e.g., a temperature) in a EUV reticle due an incident EUV radiation beam. The thermal profile may be determined using the pattern density of the reticle. The reticle is irradiated with a radiation beam having an extreme ultraviolet (EUV) wavelength. A thermal control profile may be generated using the thermal profile, which may define a parameter of the lithography process such as, a temperature gradient of a thermal control chuck. The thermal control profile may be downloaded to the EUV lithography tool (e.g., scanner or stepper) for use in a process. A separate thermal control profile may be provided for different reticles.
