Analyzing Flexibility vs. Cost for Simulated Release Profiles of a Multiple Product Waferfab
Abstract
In the course of the Smart Fabrication Flexible Fab project a risk assessment model was developed to analyze different wafer start profiles of different process flows in regard to cost and flexibility. The simulation analysis of various order release scenarios was performed with AutoSimulations' ASAP software. Simulation results generated with different wafer release profiles were evaluated in regard to t he required flexibility fulfillment through an especially developed evaluation instrument. Important key parameters such as cycle time distribution, on time delivery performance and line utilization were taken into account. Within a Philips SMST cost tool the manufacturing costs of each scenario were determined and compared to the congruent flexibility account. This approach was created to analyze beforehand various manufacturing scenarios, which could be medium- or long-term manufactured in a multiple product wafer fab. This method can be applied to optimize an already existing multi ple product manufacturing or to evaluate different manufacturing scenarios in a fab planning process.
