    摘要: A method of making a rim-type phase shift mask comprising the steps of: providing a substrate having opposing first and second surfaces, the first surface being at least partially covered with a first layer of material that substantially blocks the transmission therethrough of electromagnetic radiation of the predetermined range of wavelengths; forming a plurality of openings extending through the first layer so as to expose underlying portions of the first surface of the substrate; depositing a layer of hybrid photoresist on the first layer; exposing the second surface of the substrate to electromagnetic radiation to activate the desired portions of the hybrid photoresist; developing the photoresist, thereby exposing portions underlying the resist; and etching the exposed portions of the substrate is disclosed. The hybrid photoresist material may be exposed at varying doses to alter the placement of the area that is soluble in developer solution so that the phase shifter may be placed in various areas, but is always aligned in a fixed relationship with the edge of the blocking material.

    摘要: A mask structure and method of quantitatively measuring pellicle degradation in production photomasks by measuring overlay in test structures on the mask. A structure is located in a high transmission region close to a transition region between a low transmission and a high transmission region of the mask such that pellicle degradation impacts the printing of the object. A second structure is located in low transmission region such that the printing of the second structure overlaps the first and provides a measure of pellicle degradation.

    摘要: The invention relates to the evaluation of the pupil illumination profile in a projection lithography system using an imaging reticle featuring a plurality of holes of few microns in diameter. The imaging reticle is placed at the lens object plane and a photoresist coated substrate is exposed in a defocused position from the lithographic image plane. The image reticle has a plurality of identical holes that are regularly spaced at predetermined distances for a more detailed evaluation of the effective pupil illumination across the entire exposure field.
