The gap between VLSI technology and fabrication technology leads to strong refractive effects in lithography. Consequently, it is a huge challenge to reliably print layout features...
When VLSI technology scales toward 45nm, the lithography wavelength stays at 193nm. This large gap results in strong refractive effects in lithography. Consequently, it is a huge...
The continual shrinkage of minimum feature size in integrated circuit (IC) fabrication incurs more and more serious distortion in the optical lithography process, generating circu...
Double patterning technology (DPT) has emerged as the most hopeful candidate for the next technology node of the ITRS roadmap [1]. The goal of a DPT decomposer is to decompose the...
