  • Image sensor device and method to form image sensor device
    Patent number: 7061028
    Abstract: A new method to form an image sensor device is achieved. The method comprises forming an image sensing array in a substrate comprising a plurality of light detecting diodes with spaces between the diodes. A first dielectric layer is formed overlying the diodes but not the spaces. The first dielectric layer has a first refractive index. A second dielectric layer is formed overlying the spaces but not the diodes. The second dielectric layer has a second refractive index that is larger than the first refractive index. A new image sensor device is disclosed.
    Type: Grant
    Filed: March 12, 2003
    Date of Patent: June 13, 2006
    Assignee: Taiwan Semiconductor Manufacturing, Co., Ltd.
    Inventors: Dun-Nian Yaung, Shou-Gwo Wuu, Ho-Ching Chien, Chein-Hsien Tseng
