Abstract: A method of fabricating a phase shift mask (PSM) is described. A patterned photoresist layer is formed on an opaque layer over a transparent plate. A thin mask layer is formed on the sidewalls of the patterned photoresist layer. The exposed opaque layer and transparent plate thereunder are then removed while using the patterned photoresist layer and mask layer as a mask. A phase shift opening is formed in the transparent plate, and thereby a phase shift layer is formed at the place where the phase shift opening is located. The patterned photoresist layer and the opaque layer thereunder are then removed to expose the transparent plate. The opaque layer under the mask layer can precisely self-align the phase shift layer to prevent alignment deviation caused by multiple lithography processes. The precision of the phase shift mask can be increased, and mask manufacture cost can be lowered.

Abstract: A manufacturing method for a photomask includes a step of performing a writing operation at a predetermined scanning unit in a direction in which a head of a writing system is to be scanned (Y direction) and at a predetermined overrun unit in a direction perpendicular to the scanning direction (X direction). A pattern of the photomask includes a cyclic pattern. The writing step includes a step of writing pattern units (e.g., pixel units 20) under identical overrun conditions (e.g., a grid head 17a is aligned with the left end of each pixel unit 20 such that writing is commenced from the left end of each pixel unit 20), the pattern units including identical cyclic patterns.
Abstract: A semiconductor device manufacturing method and a semiconductor device manufacturing mask both of which make it possible to suppress a semiconductor-device global step and simply manufacture a highly-reliable semiconductor device. Square dummy patterns each having one side of, for example, 0.25 ?m or less are inserted into an area other than an actual pattern lying within a semiconductor device manufacturing mask to thereby uniformize a pattern density, enable etching processing without changing conditions set for every semiconductor device manufacturing mask and prevent an increase in global step of a post-CMP interlayer insulating film.

Abstract: A bi-layer attenuating phase shifting film and method of forming the film are described. The bi-layer film has a first layer of AlSix1Oy1 and a second layer of AlSix2Oy2. The first layer of AlSix1Oy1 and the second layer of AlSix2Oy2 are both deposited by sputtering using a sputtering system an aluminum target, a silicon target, a source of oxygen gas, and a source of argon gas. The index of refraction, n, and the extinction coefficient, k, of the deposited films are controlled by controlling the direct current, DC, power to the aluminum target and by controlling the oxygen flow rate. The values of n and k are selected to produce a bi-layer film having a transmittance of between about 15% and 45% and good chemical stability. The phase shift of the bi-layer film is determined by the index of refraction, extinction coefficient, and thickness of each of the films.
