Abstract :
The widths of refractory metal, gold, and Permalloy lines were measured as a function of design width Wi and design spacing Sj using an electrical test structure, the cross-quad-bridge resistor. The data were characterised by the following: a constant linewidth aberration ΔW; a characteristic size effect width Wc; and a characteristic proximity effect spacing Sc . With both characteristic dimensions around |c|≈|S c|≈0.4 μm, the effects on a design with W1≈S1≈1.2 μm are about (Wc/W 1)2≈10% each
