摘要:
A ferroelectric memory device manufacturing method capable of improving topology between a ferroelectric memory device and a logic device. The method for manufacturing the ferroelectric memory device includes steps of: a) forming an insulating layer on a semiconductor substrate; b) opening a capacitor region by selectively patterning the insulating layer; c) forming a bottom electrode in the opened capacitor region by using a chemical vapor deposition (CVD) method; d) forming a ferroelectric layer on a subsequent insulating layer including the bottom electrode; e) filling the ferroelectric layer on the capacitor region to a same height as that of the subsequent insulating layer surface; and f) forming a top electrode on the ferroelectric layer.

The present invention relates to an apparatus for collecting soluble component-removed powder that collects soluble component-removed and poorly soluble component-containing powder to recycle by removing the soluble component from the powder through filtering using a vacuum pump after mixing soluble component- and poorly soluble component-containing powder and a solvent dissolving the soluble component, and a method of the same. According to the invention, it can be easily achieved to collect and utilize soluble component-removed powder, after the soluble component is dissolved in a solvent, by vacuum pumping the solvent through a filter and then discharging a solution containing only the soluble component, further effectively prevent overload by removing the soluble component-removed powder stuck on the surface of the filter in the vacuum pumping through backwashing.

Disclosed herein are an optical shutter for a plasma display panel and driving method thereof. According to the present invention, an optical shutter, which employs a black organic solution that moves according to the electrowetting phenomenon and a pair of electrodes for providing voltages, is disposed on a display surface of the plasma display panel. In this state, during the non-display period, voltages are not applied to the optical shutter so that light emitted from the panel cannot transmit the optical shutter. During the display period, voltages having a different polarity are applied to the electrodes of the optical shutter so that light emitted from the panel can transmit the optical shutter. It is thus possible to completely prevent weak emission generating during the non-display period where cells are initialized and selected. Accordingly, there are effects in that contrast can be improved and the picture quality can be thus enhanced.

A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, comprising a ZnO—B2O3 group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.
摘要:
A plasma display panel (PDP) and its fabrication method are disclosed. The PDP includes a dielectric transfer film containing a ceramic pigment instead of a conventional upper dielectric layer, so that a color purity and a contrast ratio can be increased, the thickness of the dielectric thin film can be uniform, and a voltage margin and discharging can be uniform.
