    Abstract: A wafer for manufacturing image sensors is disclosed. The wafer includes an image sensor and a test key. The image sensor includes a plurality of micro-lenses; the test key includes a plurality of micro-lens samples for defects inspection. The arrangement of the micro-lens samples on the test key is substantially different from the arrangement of the micro-lenses on the image sensor. The arrangement of the micro-lens samples on the test key allows defects inspection to become less complicated.

    Abstract: A method for fabricating an image sensor is disclosed. First, a semiconductor substrate is provided, in which a photosensitive region is defined on the semiconductor substrate. At least one photosensitive material is then formed on the semiconductor substrate, and a first exposure process is performed to form a tapered pattern in the photosensitive material. A second exposure process is performed to form a straight foot pattern in the photosensitive material, and a developing process is performed to remove the tapered pattern and straight foot pattern to form the photosensitive material into a plurality of photosensitive blocks. A reflow process is conducted thereafter to form the photosensitive blocks into a plurality of microlenses.
