Abstract: An image sensor may include a dielectric, a metal interconnection, an align key, a first substrate, a photodiode, and a transparent electrode. The first substrate may include a pixel region, a peripheral circuitry region and a scribe lane. The dielectric may include a metal interconnection and an align key over the first substrate. The photodiode may be formed over the pixel region and the scribe lane. The transparent electrode may be formed over the photodiode. The align key may have a protrusion formed in a center thereof.

Abstract: A pattern mask for forming a microlens includes mask pattern parts alternately arranged and corresponding to pixel regions in a matrix, wherein neighboring corners of the mask pattern parts overlap with each other.

Abstract: A method for manufacturing a semiconductor device including coating a photo-resist layer on a semiconductor substrate having a lower layer; performing a soft-bake process on the photo-resist layer; performing an exposure process on the photo-resist layer having passed through the soft-bake process; performing a post exposure-bake (PEB) process on photo-resist pattern holes formed by the exposure process; performing a developing process on the photo-resist pattern holes having passed through the PEB process; and performing a hard-bake process on the photo-resist pattern holes having passed through the developing process. The method improves the circularity of PR pattern holes to improve the profile of contacts in an etching process after a photography process, resulting in an enhancement in the operation reliability of the device.

Abstract: A color video apparatus for displaying on-screen a hue control state of a color video signal. The apparatus includes a key input portion for inputting a hue control command of the color video signal displayed on the screen, and an on-screen-display (OSD) signal generator for generating an OSD signal for visually representing a reference color and for displaying an occupancy which indicates the degree to which the reference color contributes to the expression of a hue control state with respect to a plurality of reference colors used for expression of the hue control state, in response to the hue control command of the key input portion.
