    • A plasma etching apparatus (100) has a central processing chamber (101), an upper exhaust chamber (103) thereabove, and a lower exhaust chamber (105) therebelow. The processing chamber (101), the upper exhaust chamber (103), and the lower exhaust chamber (105) are airtightly formed by a central casing part (CC), an upper casing part (UC), and a lower casing part (LC) which are separably combined. The upper and lower exhaust chambers (103, 105) are respectively connected to upper and lower exhaust pumps (124, 132). A susceptor (114) having a support surface (114a) for supporting a target object (W), and an upper electrode or shower head (102) opposing it are arranged in the processing chamber (101). A processing gas spouted through the shower head (102) flows upward and downward toward the upper and lower exhaust chambers (103, 105) via the processing chamber (101).
    • 等离子体蚀刻设备(100)具有中央处理室(101),其上的上排气室(103)和位于其下方的下排气室(105)。 处理室101,上排气室103和下排气室105由中央壳体部分CC,上壳体部分UC和下壳体部分LC气密地形成。 ),它们可分开组合。 上部和下部排气室(103,105)分别连接到上部和下部排气泵(124,132)。 在处理室(101)内配置有具有用于支撑被处理体(W)的支撑面(114a)的基座(114)和与其相对的上部电极或喷头(102)。 通过喷淋头102喷出的处理气体经由处理室101向上下方向上下排气室103,105流动。 <图像>
