An image sensor and fabricating method thereof are provided. The image sensor can include differently microlenses formed on a pixel array substrate. The differently shaped microlenses are formed using a phase mask where the light blocking region for each microlens pattern is positioned according to the relative angle of the microlens to a main lens. The phase shift mask results in a dome shaped microlens at a region of the pixel array substrate receiving incident light from the same axis as light incident the main lens and in asymmetrical shaped microlenses with a thicker region in a portion of the microlens farthest from the dome shaped microlens.
