Abstract:
1. A method of producing a semiconductor optical sensor element, comprising the steps of: bonding a semiconductor wafer to a transparent optical wafer through an adhesive portion to form a bonded member, said semiconductor wafer including a sensor portion including a light reception portion of an optical-electric conversion element on a surface thereof, said transparent optical wafer including a light scattering portion on a surface thereof; cutting the bonded member at the adhesive portion to form the semiconductor optical sensor element formed of a sensor chip and a light scattering chip; forming a groove in the transparent optical wafer to expose the adhesive portion; and disposing a light blocking resin in the groove so that the light blocking resin remains on a side surface of the transparent optical wafer when the bonded member is cut with a dicing blade having a thickness smaller than a width of the groove.
