Abstract

The authors describe a practical methodology that can be applied to optimize the process yield of IC fabrication lines. The yield maximization problem is first reformulated into a deterministic design centering problem. Macromodeling and problem decomposition are then applied to solve the design centering problem efficiently. The effectiveness of this methodology is illustrate through a simulation example involving a CMOS process adopted from an industrial line.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
