Abstract: A camera module and a fabrication method thereof are provided. The camera module includes a lens structure and an image sensor device chip disposed under the lens structure. The lens structure includes a transparent substrate and a lens disposed on the transparent substrate. A spacer is disposed on the transparent substrate to surround the lens, wherein the spacer contains a base pattern and a dry film photoresist. The method includes forming a base pattern on a carrier and attaching a dry film photoresist on the carrier. The dry film photoresist is planarized by a lamination process and then patterned to form a spacer. A transparent substrate having a plurality of lenses is provided. The spacer is stripped from the carrier, attaching on the transparent substrate to surround each of the lenses, and then bonded with image sensor device chips.
