在半導體生產過程中,中後段的蝕刻製程扮演著重要的角色,連接上游的黃光製程並為下游的成品檢驗作好前置準備。然而,由於資源有限,新建的工廠往往無法投入昂貴的中央供酸系統以供應蝕刻機台,取而代之的是透過人工進行換酸整備以保持機台運作。在此情況下,整備時間的策略規劃成為了確保蝕刻機台能加工運作的關鍵。在高變異性的需求環境中,如何確立有效的整備時間觸發策略以最大化達交率這一生產績效指標,是半導體工廠每日面臨的挑戰。
本研究主要針對蝕刻加工站的生產策略進行探討,該策略分為兩部分,即蝕刻整備換酸和蝕刻派工。在整備策略方面,除了考量蝕刻液的壽命限制和批量設計,同時也兼顧等候區批次的延遲確認,從而提出前瞻性的批量與批次延遲確認以觸發整備,而派工策略則是在考量下一次觸發的優先性前提下,採用最短加工時間優先的方式。這兩階段的策略結合應用於蝕刻加工站,並考量了生產系統中的各種特性與限制,如整備時間與批量控管、產品重入流、急件批和重工批的優先加工等。由於生產系統中機台的加工時間具有隨機性,我們利用系統模擬軟體(Flexsim)建立了一個模擬模式進行重複模擬,以估計在不同在製品水準下的生產績效。
透過模擬分析的結果,本研究提出的蝕刻延遲優先派工法則(Etching Delay First Dispatching, EDFD)在應用於蝕刻加工站時,能在高來到率組合的背景下,提高系統達交率8%,整備次數減少6%。
In semiconductor production, the etching process is crucial, linking upstream photolithography and preparing for downstream inspections. Given resource limitations, new factories often resort to manual acid replacement for etching machine setup times. Thus, the strategic planning of setup times is essential for enabling operation. Formulating an effective setup times triggering strategy to maximize the delivery rate is a daily challenge.
This research investigates the production strategy at the etching station, focusing on etching setup times acid replacement and dispatching. The strategy considers the life limit of etching liquid, batch design, and batch delay confirmation, thereby proposing a forward-looking batch and batch delay confirmation for setup times triggering. Priority is given to the shortest processing time in dispatching. The approach integrates these elements, considering characteristics and constraints of the production system, such as batch control and priority processing of re-entered or urgent batches. The system's randomness is addressed by using the Flexsim software for simulation and production performance CLIP% estimation.
The results suggest that the proposed Etching Delay First Dispatching (EDFD) can improve the delivery rate by 8% and reduce setup times by 6% when applied to the etching station under high arrival rate conditions.
