Patent number: 7923176Abstract: A mask includes a transparent substrate, a light-blocking layer and a halftone layer. The light-blocking layer includes a source electrode pattern portion including a first electrode portion, a second electrode portion and a third electrode portion, and a drain electrode pattern portion disposed between the second electrode portion and the third electrode portion. The halftone layer includes a halftone portion corresponding to a spaced-apart portion between the source electrode pattern portion and the drain electrode pattern portion, and a dummy halftone portion more protrusive than ends of the second electrode portion and the third electrode portion. Thus, a photoresist pattern corresponding to a channel portion of a thin film transistor (TFT) may be formed with a uniform thickness, to thereby prevent an excessive etching of the channel portion.Type: GrantFiled: February 21, 2008Date of Patent: April 12, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Chong-Chul Chai, Mee-Hye Jung, Woo-Geun Lee, Woo-Seok Jeon, Young-Wook Lee, Jung-In Park, Jun-Hyung Souk, Won-Kie Chang, Shi-Yul Kim

Patent number: 7393159Abstract: An inline transfer system and method are provided for the secure transport and efficient processing of substrates such as glass substrates or semiconductor devices. A rotary conveyor is provided that includes a plurality of air nozzles which inject air to move a substrate above the plurality of air nozzles without the plurality of air nozzles making contact with the substrate. At least two independent processing units are operably coupled to the rotary conveyor. Advantageously, because a plurality of substrates may be processed in parallel, greater efficiency and flexibility are provided. Because the substrate can be moved without physical contact between the structure of the air nozzles and the substrate, the transfer is secure, clean, and efficient.Type: GrantFiled: June 7, 2004Date of Patent: July 1, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Won-Kie Chang, Gi-Cheon Yoon, Geun-Soo An
