企業要有良好競爭力面臨全球化市場之挑戰，必須仰賴製造技術不斷地改進及產品品質提升；因此，如何找出問題的癥結所在，是企業欲提升競爭力的首要課題。在企業資源有限的情形下，本研究之研究目的，乃以最少的實驗次數(較低的實驗成本)尋求一穩健的製程參數組合，達到最佳的品質水準表現。
太陽能產業的競爭力，主要在於產品差異化及整體總成本最低。由於目前矽原料大多為日、德、美等國少數供應商所掌控，使得台灣的廠商在矽原料取得之價格協商空間有限。在此限制下，太陽能廠商是否該著眼於找出太陽能生產製程中可以改善的利基點，並透過其它方法來降低整體生產成本，是本研究想探究之議題。
本研究以太陽能矽晶片(Solar Wafer)產品為研究案例，並以“線鋸切割製程”為主要之研究範圍，經由與研發/製程人員透過專家經驗法則及篩選實驗，分析出影響太陽能矽晶片良率的主要因子，找出影響製程之關鍵因子。再運用田口博士的參數設計方法從中獲得最佳化的製程參數，求得最佳的因子水準組合之改善成效，做為本研究的佐證依據，提出未來的研究方向與建議，以提供後續之研究指引。

Enterprises require powerful competitiveness to face challenges from global markets. It relies on continuous improvement of manufacture techniques and product qualities. How to find out the bottleneck of problems and to strengthen the competitiveness is the first lesson that enterprises need to learn.
The purpose of this research is to find a combined steady process recipe by a minimum number of experiments (lower experimental cost) to achieve an optimum quality under finite resources of an enterprise.
The major competitiveness in solar industry is the product differentiation and the lowest cost. As a result of the silicon materials are manipulated by a few suppliers from Japan, Germany, USA…etc. , And leads to a limited negotiation range during Taiwan vendees’ purchasing. According to this limitation, Whether the solar cell manufacturers should focus on the producing processes that can be improved, or reduce the production cost through other methods, Is the subject that this research investigates.
This research is taking “Solar wafer products” as a research case, Which majoring on “Wire Saw Process”. Try to find out the main factor of process yield and the key factor of process itself by cooperating with RD/Process experts through experts’ rule of thumb and screening experiment. Then calculate with Taguchi methodology to get an optimum recipe and best factor composition, Make them as an evidence and verification of this research. At the end, Provide a research direction and suggestion as a guidance in the future.
