| 20120026102 | ELECTRONIC APPARATUS AND METHOD OF FABRICATING THE SAME - A method of fabricating an electronic apparatus having an active region and a peripheral region surrounding the active region is described. A first main device and a second main device are provided. An optical clear liquid adhesive (OCLA) is applied between the first main device and the second main device and within the active region. A photo-mask having a transparent region and an opaque region is provided above the second main device, and the transparent region corresponds to the peripheral region. An OCLA diffusion process is performed such that the OCLA diffuses from the active region to the peripheral region. During the OCLA diffusion process, a first irradiating process with the photo-mask is performed, such that the OCLA diffusing to the peripheral region is partially cured. After removing the photo-mask, a second irradiating process is performed, such that the OCLA is completely cured. | 02-02-2012 |
