    摘要: The present invention includes a first semiconductor element forming member formed in a first layer, a first measurement mark formed by the same manufacturing step as the first semiconductor element forming member, a second semiconductor element forming member formed in a second layer above the first layer, and a second measurement mark formed in the same manufacturing step as the second semiconductor element forming member for measuring registration accuracy between the first and second semiconductor element forming members. The first measurement mark has a pattern which receives same influence of aberration as the first semiconductor element forming member when irradiated with light, and the second measurement mark has a pattern which receives same influence of aberration as the second semiconductor element forming member when irradiated with light. Thus, a registration accuracy measurement mark taking into consideration the influence of aberration can be provided.

    摘要: In an exposure process forming a predetermined circuit pattern of a semiconductor device on a wafer, a resist dimension of the resist pattern formed on a wafer and a focus position in the exposure process at a past time are measured. A resist dimension and a focus position of a wafer to which the exposure process is secondly performed are estimated by using measurement results of the measured resist dimension and focus position, and a focus offset value is calculated by using estimated values of the estimated resist dimension and focus position. Then, an exposure dose is calculated with considering this focus offset value, and a resist pattern is formed on the wafer to which the exposure process is performed by using the calculated exposure dose and focus offset value.

    摘要: The present invention provides a photomask, a semiconductor device, and a method for exposing through the photomask. The photomask comprises a photomask substrate, and an on-mask circuit area including an on-mask circuit pattern and an on-mask test mark area including an on-mask test pattern, both formed on the surface of the substrate, wherein the photomask substrate further includes an on-mask photolithography screening mark area including an on-mask comparison pattern and an on-mask screening pattern, the on-mask comparison pattern has substantially the same configuration as at least a part of the on-mask circuit pattern, and the on-mask screening pattern has substantially the same configuration as at least a part of the on-mask test pattern. The present invention allows it to measure the actual displacement generated from an overlaying (i.e. alignment) process for the purpose of eliminating of an the overlay displacement which can take place in a photolithography process.
