A method for making a semiconductor device with at least two gate regions. A target layer where user data is to be recorded is specified from the first and second layers. Adjacent fibers of the first layer pass light to distinct photo-multiplication devices. Specifically, a generic frontal face model is aligned with the frontal image and a generic profile face model is aligned with the profile image. The partition wall includes a partition membrane, and dividing projections that are protruded from the partition membrane. Other implementations are contemplated.
