    摘要: The disclosure is related to photomasks used in photolithography and methods of making photomasks. The method involves providing a transparent substrate with one or more reflective films disposed over a surface of the substrate, applying a photoresist to the solution-contacted reflective film and forming a pattern in the photoresist that is transferred to the substrate, and developing the pattern on the substrate by removing the remaining portions of the photoresist. The substrate carrying the patterned reflective film is then contacted with a solution comprising oxyanions. The disclosure is also related to photomasks made using the disclosed method.

    摘要: This disclosure includes a SRAF layout that minimizes the number of SRAFs required to reliably print contact shapes. A method is provided that reduces the number of necessary SRAF features on a mask, placing at least two elongated SRAF shapes on the mask such that the elongated SRAF shapes extend past at least one edge of a mask shape in at least one direction.
