Abstract

An image sensor module comprises an image sensor having a light sensing area, a cover glass for covering the light sensing area, a dam between the image sensor and the cover glass, which surrounds the light sensing area, and has an outer wall and an inner wall, where a cross-section of the inner wall parallel to the surface of the light sensing area of the image sensor forms a sawtooth pattern and/or, where a cross-section of the inner wall orthogonal to the surface of the light sensing area of the image sensor forms an inclined surface.
