Abstract:
A method and apparatus is provided for determining an acceptable reticle tolerance for a reticle used to produce an integrated circuit layout. The method begins by specifying a wafer target CD and a wafer CD tolerance for the integrated circuit layout. A reticle target CD is provided for the reticle that is producing the wafer target CD. A critical reticle pattern pitch is selected for the reticle target CD. The critical pattern pitch defines a relationship between the wafer CD and illumination dose exposing the reticle for producing the wafer CD which exhibits a maximum gradient. For the critical reticle pattern pitch, a relationship is established between wafer CD and a deviation from the reticle target CD that arises from use of different illumination doses. From the relationship between wafer CD and the deviation from the reticle target CD, a reticle target CD deviation interval is identified that gives rise to the wafer CD tolerance that is provided. Finally, the reticle target CD deviation interval is selected as the acceptable reticle tolerance.
Abstract:
[Problem] To provide an oxygen absorbent that has excellent oxygen absorbability at room temperature, has a low content of metals and is less odorous after oxygen absorption and an oxygen-absorbing multi-layer body comprising an oxygen absorbent layer comprising this oxygen absorbent.[Means for Dissolution] The oxygen absorbent comprises a cyclized product (A) of a conjugated diene polymer and a cyclized product (B) of a conjugated diene polymer, wherein a rate of reduction of unsaturated bonds (%) of the cyclized product (B) of a conjugated diene polymer is at least 5 points smaller than a rate of reduction of unsaturated bonds (%) of the cyclized product (A) of a conjugated diene polymer. It is preferable that the rate of reduction of unsaturated bonds of the cyclized product (A) of a conjugated diene polymer is 60% or more and that the rate of reduction of unsaturated bonds of the cyclized product (B) of a conjugated diene polymer is less than 60%. The oxygen-absorbing multi-layer body comprises a gas barrier material layer, an oxygen absorbent layer comprising the foregoing oxygen absorbent and a sealing material layer laminated in this order.
