However, due to the different characteristics of semiconductor manufacturing technologies at various stages of a technology life cycle (TLC) of some specific generation of process technology (e.g. 90nm, 65nm, etc.), satisfying different needs at each stage of a TLC under the premise that firms’ profitability can keep growing, choosing appropriate foundries has become daily critical for a fabless IC design house’s final success of innovation. In different stages of a TLC, firms have various advantages to maintain the maximum profit while assuring quality as well as on time delivery of foundry products. Albeit important, very few researches discussed how appropriate foundries can be determined. Most studies focused on the TLC only or focused on how profitable partnerships can be established. To define appropriate foundry strategies of fabless IC design houses’ to resolve the above mentioned problem which is usually faced by fabless IC design houses, this research aims to develop a fuzzy integral based fuzzy multiple criteria decision making (FMCDM) framework. Considering the characteristic of inter-dependences between criteria, a non-additive fuzzy integral based FMCDM model with ISM will be proposed for assisting decisions' makers in evaluating the most appropriate foundry strategies. Criteria for evaluating the foundry strategies at various stages of a TLC will first be summarized by literature and then be derived by using the modified Delphi process. Then, the ISM will be leveraged for deriving the decision problem structure. The Fuzzy Analytic Hierarchical Process will be leveraged for deriving weights versus each criterion. And the non-additive fuzzy integral will be leveraged to aggregate the performance value versus each alternative. Finally, foundry strategy portfolios clarify by cluster analysis method from the performance derived from fuzzy integral. An empirical study based on evaluating Taiwanese semiconductor experts will be leveraged to demonstrate the feasibility of the proposed MCDM framework. Criteria for evaluating and selecting foundries over a TLC will be derived. Further, the empirical study results can be leveraged by fabless design houses.半導體晶圓代工廠模糊積分無晶圓廠積體電路設計公司模糊多準則決策Semiconductor foundryFuzzy IntegralFabless IC design houseFuzzy Multi-criteria Decision-making (FMCDM)以基於模糊積分之模糊多準則決策架構擬定積體電路 設計公司不同技術生命週期階段之晶圓代工策略A Fuzzy Integral Based FMCDM Framework for Semiconductor Foundry Strategy Definitions at Various Stages of a Technology Life Cycle
