    摘要: A method of making a photolithography mask for use in creating an electrical fuse on a semiconductor structure comprises initially determining a pattern for a desired electrical fuse, with the pattern including a fuse portion of substantially constant width except for a localized narrowed region of the fuse portion at which the electrical fuse is designed to blow. The method then includes providing a photolithography mask substrate and creating on the photolithography mask substrate a fuse mask element adapted to absorb transmission of an energy beam. The fuse mask element has a first mask portion of substantially constant width corresponding to the desired electrical fuse pattern portion of substantially constant width, and a second mask portion corresponding to the localized narrowed region of the fuse portion. The second mask portion comprises either an additional mask element spaced from the first mask portion, a narrowed width portion, or a gap in the first mask portion. The second mask portion is of a configuration sufficient to create a latent image of the electrical fuse pattern, including the localized narrowed region of the fuse portion at which the electrical fuse is designed to blow, upon passing the energy beam through the photolithography mask and onto a resist layer. Preferably, the fuse portion of substantially constant width on the determined fuse pattern has a design width less than about 0.25 &mgr;m, and wherein the localized narrowed region of the fuse portion has a design width less than the design width of the fuse portion.

    摘要: A method for forming a mask layout is described. A plurality of phase shapes are formed on either side of a critical feature of a design layout of an intergrated circuit chip having a plurality of critical features. A plurality of transition edges are identified from the edges of each phase shape. Each transition edge is parallel to critical feature. A transition space is identified as defined by one of the group including two transition edges and one transition edge. A transition polygon is formed by closing each transition space with at least one closing edge. Each transition polygon is transformed into a printing assist feature. A mask layout is formed from the printing assist features and critical features.

    摘要: Embodiments of the present invention provide a method of placing printing assist features in a mask layout. The method includes providing a design layout having one or more designed features; generating a set of parameters, the set of parameters being associated with one or more printing assist features (PrAFs); adding the one or more PrAFs of the set of parameters to the design layout to produce a modified design layout; performing simulation of the one or more PrAFs and the one or more designed features on the modified design layout; verifying whether the one or more PrAFs are removable based on results of the simulation; and creating a set of PrAF placement rules based on the set of parameters, if the one or more PrAFs are verified as removable. The set of PrAF placement rules may be used in creating a final set of PrAF features to be used for creating the mask layout.
