Abstract
The present disclosure, in some embodiments, relates to an image sensor integrated chip. The image sensor integrated chip includes a semiconductor substrate. One or more isolation structures are arranged within one or more trenches in the semiconductor substrate. The one or more trenches are disposed along opposing sides of a photo diode region within the semiconductor substrate. The semiconductor substrate includes an undulating exterior having rounded corners arranged laterally between neighboring ones of a plurality of flat surfaces. The rounded corners and the plurality of flat surfaces forming a plurality of triangular shaped protrusions arranged between the one or more isolation structures, as viewed along a cross-sectional view.
