晶圓代工機台採購類型及採購決策要素分析

Abstract

晶圓代工機台採購類型及採購決策要素分析 研究生：黃塗生 指導教授：洪志洋教授 國立交通大學科技管理研究所 碩士在職專班 摘要 在晶圓代工產業中，固定資產支出佔總支出之大宗。而機台採購支出又為資本支出中最為重要，且會影響產出之關鍵要素。本研究主要是分析關於台灣晶圓代工產業（foundry）台積電及聯電之機台採購，研究機台採購類型、機台採購決策要素、及機台採購與營收之關係，利用專家訪談，層別分析法（AHP），敘述統計，迴歸分析，得出影響機台採購之決策要素主要為景氣循環、客戶及訂單需求及機台能力，在財務需求及人力資源上並非重要之考量。本論文以此結果，論述台灣在未來晶圓代工產業的發展上，所需投注之資源及考量之要素。 關鍵字：晶圓代工、機台採購、專家訪談、層別分析法（AHP）、迴歸分析

Types and decisions of Equipment Purchasing of Taiwan’s IC Foundries Student: Tu-Sheng Huang Advisor: Dr. Chih-Young Hung Institute of Management of Technology National Chiao Tung University Abstract For firms in the IC foundry industry, expenditures on fixed assets are almost always the largest part in their annual budgets. In turn, equipment purchasing constitutes the major element in the expenditure on fixed assets. Despites of its adverse effect on the cash flows of an IC foundry firm, the purchasing of equipment is important to the firm’s capability in terms of wafers ship-out. The focus of this thesis is on the equipment purchasing of Taiwan’s IC foundries. Specifically, three issues are addressed. First, an analysis is made to classify the types of equipments purchased. We found that the types of equipments purchased can be classified by the following six factors: process capability, materials, product requirements, product mix, product types, and purpose. Second, a decision model of equipment purchasing is proposed. Lastly, we investigate the relationship between the revenue and the expenditure for IC foundries. Data of two of the largest foundries in Taiwan are collected and analyzed. Research methods include expert interviews, AHP, descriptive statistical analysis, and lagged regression analysis. The results of our statistical analysis suggest that people in charge of equipment-purchasing decisions of the IC foundries in Taiwan seem to be able to anticipate and act accordingly to the business cycle of IC industry.
