    摘要: A novel composite layer structure method which is suitable for reducing post-exposure delay (PED) effects associated with fabricating a photolithography reticle or mask and eliminating or at least minimizing variations between intended and realized critical dimension values for a circuit pattern fabricated on the reticle or mask. The method includes providing a mask blank having a metal layer, providing a photoresist layer on the metal layer of the mask blank, providing a protective layer on the photoresist layer and photo-cracking the photoresist layer in the desired circuit pattern typically by electron beam exposure. During subsequent post-exposure delay periods, the protective layer prevents or minimizes Q-time narrowing of the photo-cracked photoresist, and consequently, prevents or minimizes narrowing of the critical dimension of a circuit pattern etched in the metal layer according to the width of the photo-cracked photoresist.

    摘要: Structure of mask blanks and masks, and methods of making masks are disclosed. The new mask blank and mask comprise a tripe etching stop layer to prevent damages to the quartz substrate when the process goes through etching steps three times. The triple etching stop layer may comprise a first sub-layer of tantalum containing nitrogen (TaN), a second sub-layer of tantalum containing oxygen (TaO), and a third sub-layer of TaN. Alternatively, the triple etching stop layer may comprise a first sub-layer of SiON material, a second sub-layer of TaO material, and a third sub-layer of SiON material. Another alternative may be one layer of low etching rate MoxSiyONz material which can prevent damages to the quartz substrate when the process goes through etching steps three times. The island mask is defined on the mask blank by using various optical proximity correction rules.
