Abstract: Provided are a CMOS image sensor and a fabricating method thereof. The CMOS image sensor includes a device isolation layer, a plurality of photodiode regions, an interlayer insulating layer, a refracting layer, a planarizing layer, a color filter layer, and a plurality of microlenses. The refracting layer, with a higher refractive index than that of the interlayer insulating layer, is formed through the interlayer insulating layer on portions of the device isolation layer, to divide the interlayer insulating layer and give the divided portions thereof the characteristics of a waveguide.

Abstract: An image sensor including a diffractive lens simplifies a fabrication process and minimizes loss. The image sensor includes a diffractive lens as an inner lens between a color filter portion and a photodiode for compensating sensitivity to a light received. A method for fabricating the image sensor includes forming a diffractive lens as an inner lens between a color filter portion and a photodiode for compensating a sensitivity to a light received.

Abstract: A CMOS image sensor includes a passivation layer including an etch stop layer, the passivation layer having a color filter array pattern formed to a depth determined by the etch stop layer, the color filter array pattern including separately defined color filter regions; and a color filter array including a plurality of color filters for respectively filtering light according to color, the color filters being formed according to the color filter array pattern, each color filter formed of a material filling only a corresponding color filter region.

Abstract: Provided is a secondary battery of an assemble-type structure, comprising: a cell body including an electrode assembly of cathode/separator/anode sealed therein; and a cap assembly including a protection circuit electrically connected to the cell body so as to control overcharge, overdischarge and overcurrent of the battery and a cap housing covering an upper part of the battery, and being detachably coupled to the cell body. In accordance with the present invention, since the cap assembly including the protection circuit, cap housing and the like is assembled detachably from the cell body and electrically connected to and also can be physically firmly fixed to one another, provided are effects capable of greatly reducing the manufacturing process steps of the battery, and solving all the problems associated with use of battery cases and insert injection molding.
