Publication number: 20040087050Abstract: A reflective layer 10 is formed on a back surface 11b of a sapphire substrate 11. The reflective layer 10 includes an extension portion 10a which extends so as to cover almost all the sidewalls 21a of a light-emitting device in the vicinity of the sapphire substrate.

Publication number: 20040087067Abstract: A first contact hole (6) is formed penetrating a gate insulating film (5), on which a gate electrode (7g) is formed and simultaneously a first contact (7s, 7d) is formed in the first contact hole. A second contact hole (9) penetrating an interlayer insulating film (8) is formed, and a second contact (10) is formed in the second contact hole (9). A third contact hole (11) is formed penetrating a planarization film (26), and an electrode (40) is formed in the third contact hole (11). By using a plurality of contact holes for electrically connecting the electrode (40) and a semiconductor film (3), the aspect ratio of each contact hole can be reduced, thereby achieving improvement in yield, high-level integration due to a reduction in difference in area between upper and bottom surfaces of the contact, and other advantageous improvements.Type: ApplicationFiled: January 16, 2003Publication date: May 6, 2004Inventors: Kiyoshi Yoneda, Tsutomu Yamada, Shinji Yuda, Koji Suzuki

Publication number: 20040087072Abstract: A method of forming an active device is provided. The method includes performing a first patterning operation on a first plurality of layers. This first patterning operation defines a first feature of the active device. Then, a second patterning operation can be performed on at least one layer of the first plurality of layers. This second patterning operation defines a second feature of the active device. Of importance, the first and second patterning operations are performed substantially back-to-back, thereby ensuring that the active device can accurately function.Type: ApplicationFiled: October 7, 2003Publication date: May 6, 2004Inventors: Michael A.
