Patent ID: 7500208

Claim:
A method of line evaluation, comprising the steps of: (a) providing a line evaluation structure comprising N electrically conductive lines, wherein N is a positive integer, wherein, for i=1,2, . . . ,N, the i th line of the N electrically conductive lines comprises M i line sections, M i being a positive integer, such that the N electrically conductive lines comprise in total S line sections, wherein S=ΣM i (i=1,2, . . . ,N), wherein each line section of the S line sections is of the same length, and (b) measuring electrical resistance of each line section of the S line sections; and (c) determining a line geometry adjustment for the line evaluation structure based on the electrical resistances of the S line sections obtained in step (b), wherein the line geometry adjustment represents an effective reduction of cross-section size of the N electrically conductive lines as a result of grain boundary electrical resistance.
