DETECTION DEVICE AND METHOD FOR PRODUCING DETECTION DEVICE

WIPO Patent Application WO/2022/168523

A1

This detection device (1) comprises: a first substrate (21); a plurality of photodiodes (30) which are provided on the first substrate (21); and a light filter layer (75) which comprises a plurality of translucent regions (78) that are respectively superposed on the plurality of photodiodes (30), a light-blocking region (76) that is provided between the plurality of translucent regions (78), and a projection part (77) that protrudes from a surface of the light-blocking region (76), the surface facing the first substrate (21). This method for producing a detection device (1) comprises: a step for forming a plurality of photodiodes (30) on a first substrate (21); a step for forming a light filter layer (75) on a second substrate (71), the light filter layer (75) comprising a plurality of translucent regions (78), a light-blocking region (76) that is provided between the plurality of translucent regions (78), and a projection part (77) that protrudes upward from the light-blocking region (76); and a step for bonding the first substrate (21) and the second substrate (71) to each other in such a manner that the projection part (77) is positioned between adjacent photodiodes (30).
