在薄膜濺鍍的過程當中，系統操作者所關心的乃是濺鍍率、靶材的使用率以及基材塗佈的均勻度，而這些皆會受到環境中的電磁場、腔體溫度以及壓力等諸多變數的影響。其中靶材為製作薄膜時最重要的原料，在薄膜製作的過程中，靶材會受到離子的撞擊進而使靶材原子濺射至基材形成薄膜。因此當靶材的某一區域被離子長時間的撞擊後，靶材原料會逐漸變薄，而一旦被擊穿後，便無法再使用。當整塊靶材被擊穿時，其原料的使用率一般來說只使用了大概3-5成左右，造成相當地浪費，及相對的成本增加。所以本論文是希望在既有的磁控濺鍍機架構下，透過適當的結構調整，以達到提升靶材的使用率以及濺鍍率的目標。經由論文中的探討分析以及三維系統運動方程式模擬電子活動軌跡的結果得知，透過額外地加入鐵環以及補償永磁，並利用田口法在結構上做一個完整的設計與規劃，即可適當地改變磁控濺鍍機架構中腔體內磁場的分布。如此即可使得靶材表面附近的電子運動軌跡受到控制，即能間接調控靶材蝕刻軌跡以及轟擊靶材的離子數量，不但能使靶材達到更有效的利用也能使濺鍍率提升，如期地達到本研究的目的。

In the process of sputtering, what a system operator concerns are the sputtering rate, target utilization, and substrates uniformity. All of them are influenced by variables such as electromagnetic environment, chamber temperature, and pressure. In thin film manufacturing, targets bombarded by ions will sputter atoms to the substrates in order to make thin films; therefore, when a certain target zone is extensively bombarded by ions, target surface will become thinner. In general, when certain part of the target is penetrated, it is no longer usable while utilization rate only from 30 to 50 percent. It causes considerable waste and relatively higher costs. As a result, the objective of this study is to enhance target utilization and the sputtering rate through appropriate adjustment in the structure of the existing DC Magnetron Sputtering System (MSS). Since, the magnetic field distribution in the chamber will be appropriately adjusted inside the DC MSS with extra iron annulus and active compensation magnetizations being added. However, in order to get the better structural refinement of DC MSS it needs a thorough design and management based on Taguchi Method. Then, based on such structural adjustment, electron trajectories on top surface of targets can be conveniently controlled, and target erosion patterns and the number of ions bombarding the target will be indirectly controlled. It will, as a result, achieve the objective of this study by enhancing not only the target utilization efficiency but the sputtering rate.
