Abstract
An optical device package includes a semiconductor substrate, and an optical device. The semiconductor substrate has a first surface, a second surface different in elevation from the first surface, and a profile connecting the first surface to the second surface. A surface roughness of the profile is greater than a surface roughness of the second surface. The optical device is disposed on the second surface and surrounded by the profile.
