摘要:
A dry etching apparatus used for manufacture of a semiconductor device includes a plasma confinement ring secured by screws to a cathode, an anode, and a metal focusing ring extending around the anode for enhancing the uniformity of the plasma. The screws are located a maximum distance away from the focusing ring. Thus, micro-arcing is prevented from occurring between the focusing ring and the screws. The confinement ring is also designed to distribute the plasma stream only onto the wafer, so that the generation of contamination particles is suppressed during etching.

There is provided an electronic paper display device and a manufacturing method thereof. The electronic paper display device includes a first electrode formed of a transparent material; at least one or more second electrodes disposed to face the first electrode with differing gaps therebetween; and at least one or more display units disposed between the first and second electrodes and having optical properties varied according to voltage applied to the first and second electrodes. The display units are disposed between the first electrode and the second electrodes disposed to face the first electrode with differing gaps, so respective rotation amounts or rotation angles of the display units become different when the same magnitude of voltage is applied. Accordingly, a wide range of contrast levels is displayed.
