Patent number: 7792006Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.Type: GrantFiled: May 29, 2007Date of Patent: September 7, 2010Assignee: Industrial Technology Research InstituteInventors: Chih King Lee, Liang Bin Yu, Jiunn Woei Liaw, Ding Zheng Lin, Jyi Tyan Yeh, Yu Tsung Chiu, Chun Ti Chen, Chyan Chi Wu, Chau Shioung Yeh, You Chia Chang, Kuo Tung Huang, Yi Chun Chen, Yeong Feng Wang

Patent number: 7646021Abstract: A TFT array substrate includes a substrate, a patterned first metallic layer, a patterned stack layer, a patterned dielectric layer, a patterned transparent conductive layer, and a patterned third metallic layer. Elements of each TFT in the TFT array substrate are arranged vertically, so that the TFT array substrate has relatively small fabrication area and is operable with a high conducting current. Further, the storage capacitance can be enhanced by enclosing or sandwiching the second metallic layer with the common lines and the transparent electrodes. In such a way, pixel flashing caused by those coupled signals can be reduced, thus promoting displaying quality thereof.Type: GrantFiled: March 11, 2009Date of Patent: January 12, 2010Assignee: Au Optronics CorporationInventors: Yeong-Feng Wang, Chih-Jui Pan, Liang-Bin Yu
