摘要： In designing a semiconductor integrated circuit, circuit information used for circuit simulation is extracted from measurement values of electric characteristics of a device included in TEG and parameters included in a netlist are modified using the measurement values and simulation values. Circuit simulation is carried out using the thus modified netlist to lead to a decrease in error in the circuit simulation which is caused due to difference between design dimension and actual finished dimension, thereby preventing an increase in design margin and a yield lowering by malfunction.

摘要： In a cell comprising an N well and a P well, a distance SP04 from a center line of a contact N-type region to an N well end of the N well is set to be a distance which causes a transistor not to be affected by resist. A distance from a well boundary to the center line of the contact N-type region is equal to SP04. A design on the P well is similar to that on the N well. Thereby, modeling of the transistor in the cell can be performed, taking into consideration an influence from resist in one direction. Also, by fabricating a cell array which satisfies the above-described conditions, design accuracy can be improved.
摘要翻译：在包括N阱和P阱的单元中，从接触N型区域的中心线到N阱的N阱端的距离SP04被设定为使晶体管不受影响的距离抗。从阱边界到接触N型区域的中心线的距离等于SP04。 P井的设计与N井相似。因此，考虑到在一个方向上的抗蚀剂的影响，可以对单元中的晶体管进行建模。此外，通过制造满足上述条件的单元阵列，可以提高设计精度。
