Patent ID: 7598118

Claim:
A method of manufacturing a semiconductor sensor, the method comprising: forming a plurality of cap portions by using a resin on a single separable agent formed on a supporting substrate, the cap portions being formed on the single separable agent to be separated from each other; forming a cavity in each of the cap portions, wherein: the forming of a cavity in each of the cap portions includes forming a cap layer on the single separable agent; forming a first mask on the cap layer to have apertures at positions corresponding to the cavity in each of the cap portions; etching the cap layer using the first mask, so as to form the cavity in each of the cap portions; removing the first mask; forming a second mask to have apertures at positions corresponding to dividing positions of the cap portions on the cap layer after the removing of the first mask; dividing the cap layer into the cap portions by etching using the second mask; and removing the second mask; preparing a semiconductor wafer, on which a plurality of sensor elements are formed; fixing the cap portions, which have been formed on the supporting substrate via the single separable agent, to the semiconductor wafer such that the cavity in each of the cap portions corresponds to each of the sensor elements; and separating the single separable agent together with the supporting substrate from the cap portions so as to leave the cap portions on the semiconductor wafer.
