Morphology
photolithography = lithography (opaque) = photo + litho + graph + y
The word is formed by adding photo- to lithography, but the resulting technical meaning is not recoverable for an average B1 learner from the parts alone.
Etymology
Photolithography breaks into photo- 'light', litho- 'stone', and -graphy 'writing or drawing'. It originally meant 'printing from a stone using light', so today photolithography means using light and photographic images or masks to draw or print very small patterns, for example on microchips.
