Patent number: 7622778Abstract: In one embodiment, a semiconductor device has an active region defined by an isolation layer formed inside an STI trench that includes an upper trench and a lower trench having a substantially curved cross-sectional profile under the upper trench so that the lower trench is in communication with the upper trench. Since the upper trench has a sidewall tapered with a positive slope, a good gap filling property can be obtained when filling the upper trench with an insulating layer. By forming a void in the lower trench, a dielectric constant at the bottom of the isolation layer is lower than a dielectric constant at an oxide layer, thereby improving the isolation property. The isolation layer includes a first insulating layer formed inside only the upper trench and covering an inner wall of the upper trench in the form of a spacer.Type: GrantFiled: May 12, 2006Date of Patent: November 24, 2009Assignee: Samsung Electronic Co., Ltd.Inventors: Sung-Sam Lee, Gyo-Young Jin, Yun-Gi Kim

Patent number: 7521866Abstract: A plasma display panel is provided that has an inter-electrode distance in a structure where a black layer and an electrode are separated from each other. The plasma display apparatus may have the effect that reactive current is reduced by lowering capacitance. Further, the plasma display panel may have the effect that emission of light by discharge is smoothly performed by controlling a width of an upper and lower portion of a second barrier rib and a width of the first barrier rib according to the width of the upper portion of the second barrier rib such that a luminance can be increased and interference of adjacent cells can be minimized. This may have an effect that a sustain period where an image is displayed can be secured relatively longer since an address time during which the scan pulse is applied is reduced.Type: GrantFiled: March 19, 2007Date of Patent: April 21, 2009Assignee: LG Electronics Inc.Inventors: Youn Jin Jung, Yun Gi Kim
