Publication number: 20060108911Abstract: A surface light source device includes a light source body having a plurality of discharge spaces that are divided into a light-emitting region and a non-light-emitting region. The light-emitting region has a first cross sectional area. The non-light-emitting region has a second cross sectional area larger than the first cross sectional area. An electrode for applying a voltage to a discharge gas, which is injected into the discharge spaces, is provided to a portion of the light source body corresponding to the non-light-emitting region. Thus, a larger amount of the discharge gas may be distributed in the non-light-emitting region than in the light-emitting region. As a result, the electrode may not serve as a dark field. Further, the surface light source device may have a long life span.Type: ApplicationFiled: November 14, 2005Publication date: May 25, 2006Inventors: Hyun-Sook Kim, Jae-Seok Park, Kil-Ho Kim, Seog-Hyun Cho

Patent number: 6831007Abstract: A method for forming a metal line of an Al/Cu structure is disclosed. In a state where a first Ti/TiN layer, an Al layer, and a second Ti/TiN layer are layered, the grooves are formed by etching the upper half the Al layer using a photoresist film, which is formed on the second Ti/TiN layer by a negative patterning process, as a mask. After a third Ti/TiN layer and a Cu layer are formed in the grooves, the third Ti/TiN (buffer) layer, the second Ti/TiN layer, the Al layer, and the first Ti/TiN layer are etched using the Cu layer as a mask. Thus, the metal line having a layered structure of the first Ti/TiN layer, the Al layer, the third Ti/TiN layer, and the Cu layer is formed. In such case, since thickness of the photoresist film has decreased by half the thickness of the Al layer, the photoresist film can finely be patterned.Type: GrantFiled: March 14, 2002Date of Patent: December 14, 2004Assignee: Hynix Semiconductor Inc.Inventor: Kil Ho Kim
