Abstract:
A method for fabricating a solid state image sensor comprising the steps of:(1) attaching a UV tape on a wafer after forming first microlens layers opposite to photodiode regions respectively and second microlens layers on an entire surface inclusive of the first microlens layers;(2) subjecting the wafer to die sawing along a scribe line on the wafer for individualization of devices;(3) directing a UV ray onto an entire surface of the wafer directly, to harden an adhesive composition on the UV tape for the first time, and to harden the adhesive composition again by the UV ray reflected at the second microlens layer; and,(4) attaching a remove tape on the UV tape passed through the step (3) and removing the UV tape and foreign residual matters using the remove tape.
